NOAA's latest generation of geostationary weather satellites
The Geostationary Operational Environmental Satellite (GOES) – R Series is the nation’s most advanced fleet of geostationary weather satellites. The GOES-R Series significantly improves the detection and observation of environmental phenomena that directly affect public safety, protection of property and our nation’s economic health and prosperity.
The satellites provide advanced imaging with increased spatial resolution and faster coverage for more accurate forecasts, real-time mapping of lightning activity, and improved monitoring of solar activity and space weather.
The GOES-R Series is a four-satellite program (GOES-R/S/T/U) that will extend the availability of the operational GOES satellite system through 2036.
Remote environmental sensing is only part of the GOES-R Series mission. The satellites also provide unique capabilities to relay data directly to users to meet critical needs
DCS is a satellite relay system used to collect information from Earth-based data collection platforms that transmit in-situ environmental sensor data from more than 20,000 platforms across the hemisphere.
GOES Rebroadcast provides the primary relay of full resolution, calibrated, near-real-time direct broadcast space relay of Level 1b data from each instrument and Level 2 data from the Geostationary Lightning Mapper (GLM). GRB replaces the GOES VARiable (GVAR) service
The Emergency Managers Weather Information Network (EMWIN) is a direct service that provides users with weather forecasts, warnings, graphics and other information directly from the National Weather Service (NWS) in near real-time. The HRIT service is a new high data rate (400 Kpbs) version of the previous LRIT (Low Rate Information Transmission), broadcasting GOES-R Series satellite imagery and selected products to remotely-located user terminals.
The SARSAT system detects and locates mariners, aviators and other recreational users in distress. The GOES-R Series continues the legacy function of the SARSAT system on board NOAA’s GOES satellites. This system uses a network of satellites to quickly detect and locate signals from emergency beacons onboard aircraft, vessels and from handheld personal locator beacons. The GOES-R Series SARSAT transponder operates with a lower uplink power than the current system (32 bBm), enabling GOES-R Series satellites to detect weaker beacon signals.
The GOES-R series spacecraft bus is three-axis stabilized and designed for 10 years of on-orbit operation preceded by up to five years of on-orbit storage. The spacecraft carries three classifications of instruments: nadir-pointing, solar-pointing, and in-situ. Visit the Spacecraft page of this site for more information.

The most recent images of Earth's western hemisphere from the GOES constellation.
Environmental satellites provide data in several different formats. The most commonly used channels on weather satellites are the visible, infrared, and water vapor.
Visible satellite images, which look like black and white photographs, are derived from the satellite’s signals. Clouds usually appear white, while land and water surfaces appear in shades of gray or black. The visible channel reflects solar radiation. Clouds, the Earth's atmosphere, and the Earth's surface all absorb and reflect incoming solar radiation. Since visible imagery is produced by reflected sunlight (radiation), it is only available during daylight.
In the infrared (IR) channel, the satellite senses energy as heat. The Earth’s surface absorbs about half of the incoming solar energy. Clouds and the atmosphere absorb a much smaller amount. The Earth’s surface, clouds, and the atmosphere then re-emit part of this absorbed solar energy as heat. The infrared channel senses this re-emitted radiation. Infrared imagery is useful for determining cloud features both at day and night.
Water vapor imagery is used to analyze the presence and movement of water vapor moisture in the upper and middle levels of the atmosphere. The wavelength spectrum used to detect water vapor is in the 6.7 to 7.3 micrometer wavelength range. The darker regions in water vapor imagery are areas where very little water vapor exists in the middle and upper troposphere, and the lighter regions are very moist. Water vapor imagery is a very valuable tool for weather analysis and prediction because water vapor imagery shows moisture in the atmosphere, not just cloud patterns. This allows meteorologists to observe large-scale circulation patterns even when clouds are not present.
The National Oceanic and Atmospheric Administration (NOAA) maintains two primary constellations of environmental satellites: geostationary and polar-orbiting. These satellites are part of NOAA's integrated observing system, which includes satellites, radar, surface automated weather stations, weather balloons, sounders, buoys, instrumented aircraft and other sensors, along with the data management infrastructure needed for this system.
Geostationary satellites orbit 35,800 km (22,300 miles) above Earth's equator at speeds equal to Earth's rotation, which means they maintain their positions and provide continuous coverage. Information from geostationary satellites is used for short-term (1 day) weather forecasting and severe storm warning and tracking.
Polar-orbiting satellites make regular orbits around the Earth’s poles from about 833 km (517 miles) above the Earth’s surface. The Earth constantly rotates counterclockwise underneath the path of the satellite, making for a different view with each orbit. Information from polar-orbiting satellites is used for mid-range (3-7 day) forecasts and advanced warnings of severe weather.
GOES satellites continually view the continental United States, Pacific and Atlantic Oceans, Central and South America, and Southern Canada. To fully cover Alaska, Hawaii, the entire continental United States and the Pacific and Atlantic Oceans (for tropical storms), NOAA operates two GOES satellites simultaneously: GOES East and GOES West. GOES East is located at 75.2° W and provides most of the U.S. weather information. GOES West is located at 137.2°W over the Pacific Ocean. In addition to two operational satellites, NOAA also maintains an on-orbit spare.
Since 1975, GOES have provided continuous imagery and data on atmospheric conditions and solar activity (space weather). They have even aided in search and rescue of people in distress. GOES data products have led to more accurate and timely weather forecasts and better understanding of long-term climate conditions. NASA builds and launches the satellites and NOAA operates them.
GOES-R launched on November 19, 2016, and was followed by GOES-S on March 1, 2018. GOES-T launched on March 1, 2022, and GOES-U is planned for launch in 2024.
GOES-T, the third satellite in the GOES-R Series, launched on March 1, 2022. GOES-T lifted off from Space Launch Complex 41 at Cape Canaveral Space Force Station, Florida, aboard an Atlas V 541 rocket. GOES-T reached geostationary orbit on March 14, 2022, and was renamed GOES-18. GOES-18 replaced GOES-17 as the operational GOES West satellite at 137.0 degrees west longitude on January 4, 2023.
GOES-S launched on March 1, 2018 and was renamed GOES-17 when it reached geostationary orbit on March 12, 2018. GOES-17 joined its sister satellite, GOES-16, in orbit. The first satellite in the series, GOES-R, launched on November 19, 2016, and became GOES-16 when it reached geostationary orbit. GOES-16 replaced GOES-13 as NOAA’s operational GOES East satellite at 75.2 degrees west longitude on December 18, 2017. GOES-17 served as GOES West from February 12, 2019 until it was replaced by GOES-18 on January 4, 2023. GOES-17 is now the on-orbit standby for the operational constellation.
GOES-U is planned for launch in April 2024.
GOES satellites are placed into a geosynchronous orbit that keeps them over a specific location on the earth. By maintaining a position hovering over a fixed point on Earth's surface, GOES are able to constantly monitor atmospheric conditions in a particular portion of the Earth's atmosphere. Note that non-geosynchronous orbits (for example polar orbits) move over an ever-rotating earth underneath them, therefore seeing a constantly changing view, which has advantages for other types of missions.
GOES-16 became operational as NOAA’s GOES East on December 18, 2017, replacing GOES-13. From its operational location of 75.2 degrees west longitude, GOES-16 is keeping watch over most of North America, including the continental United States and Mexico, as well as Central and South America, the Caribbean, and the Atlantic Ocean to the west coast of Africa.

Since May 15, 2023, NOAA satellites have been watching Mexico’s Popocatépetl Volcano exhibit activity ranging from tremors to spewing ash. Popocatépetl, Aztec for smoking mountain, is located 45 miles southeast of Mexico City. With about 25 million people living within 60 miles of Popocatépetl, it is considered one of the most dangerous volcanoes in the world. Geostationary satellites, like GOES-16 and GOES-18, are the primary tool for monitoring volcanic clouds. GOES-16 observed Popocatépetl’s ash plumes in near real-time and monitored hazardous sulfur dioxide from the volcano. JPSS satellites measured smoke, ash and dust from the volcano. Together, NOAA satellites help monitor volcanoes and the risks they pose.
In early May 2023, fires ignited across western Canada due to unusually hot and dry weather. NOAA satellites watched as the fires raged, burning about one million acres. GOES-18 monitored the spread of the fires and smoke across the region. The ABI instrument on GOES-18 observed the formation of pyrocumulonimbus clouds from intense fires in Alberta. The data collected by NOAA satellites help responders forecast what areas will be impacted and manage the wildfires. As the Northern Hemisphere heats up, NOAA satellites will keep watch for wildfires.
Today, NOAA awarded the Geostationary Ground Sustainment Services (GGSS) contract to L3Harris Technologies Inc. of Palm Bay, Florida. The five-year Indefinite Delivery/Indefinite Quantity (IDIQ) contract will provide sustainment services to extend the functions of the ground system that supports NOAA’s GOES-R Series. This contract provides for an indefinite quantity of supplies and services during the contract ordering period from May 11, 2023, through May 10, 2028. Individual supplies and service requirements will be defined at the task order level. The maximum value of this IDIQ contract is $275,169,157. The work will be performed at NOAA facilities located in Suitland, Maryland; College Park, Maryland; Wallops Island, Virginia; and Fairmont, West Virginia; and at the L3Harris facility in Melbourne, Florida.
As spring heads toward summer, NOAA satellites are ready for this year’s upcoming hurricane season. NOAA satellites monitor the conditions that spawn hurricanes and provide early warning that a storm is forming. GOES East and West monitor hurricanes as they develop and track their movements in near real-time. GOES satellites measure the temperature of cloud tops and the amount of water vapor present within a system, and also provide wind estimates. They also monitor lightning within a storm. NOAA satellites also aid emergency response to landfalling hurricanes by mapping the extent, damage and duration of flood events. Together, NOAA satellites are prepared to provide vital information to forecasters and help protect life and property throughout the 2023 hurricane season and beyond.
GOES-U, the fourth and final satellite in NOAA’s GOES-R Series, recently completed a successful test deployment of its solar array to ensure it will function properly in space. This critical test verified that the satellite's large, five-panel solar array — which is folded up when the satellite is launched — will properly deploy when GOES-U reaches geostationary orbit. GOES-U’s solar array will convert energy from the sun into electricity to power the entire satellite, including the instruments, computers, data processors, sensors, and telecommunications equipment. GOES-U is scheduled to launch in 2024.
On April 21, 2023, NOAA satellites detected a coronal mass ejection erupting from the sun, which hurled plasma at two million miles per hour toward Earth. This eruption produced a geomagnetic storm on Earth. GOES-16’s Solar Ultraviolet Imager (SUVI) instrument observed the event as it occurred, while the DSCOVR satellite measured the solar winds the storm produced. This allowed NOAA to issue warnings for possible impacts from the storm. Geomagnetic storms can affect electrical grids, spacecraft, radio frequencies, GPS signals, and astronauts in space. On April 23, the particles reached Earth’s upper atmosphere and caused an aurora in both the Northern and Southern Hemispheres. This is the third severe geomagnetic storm since Solar Cycle 25 began in 2019. As the sun’s activity continues to ramp up, NOAA satellites will be watching for hazardous space weather.
Since 1970, NOAA satellites have been monitoring Earth’s weather, environment, oceans, and climate. This Earth Day, we have a lot to celebrate. Over the past year, NOAA has added two new satellites to its Earth-observing fleet and contributed an instrument to a mission that will help us have a better understanding of Earth’s physical and biological environment. On Earth Day, we celebrate the critical information NOAA satellites provide to help us stay safe and the beautiful imagery they share of our planet. They see it all: hurricanes, severe thunderstorms, lightning, fires, dust storms, smoke, fog, volcanic eruptions, vegetation, snow and ice cover, flooding, sea and land surface temperature, ocean health and more. They can even track ship traffic and power outages. At NOAA, each day is Earth Day.
The GOES-R/GeoXO quarterly newsletter for January – March 2023 is now available. 2023 is off to an exciting start! We are just a little over a year away from the GOES-U launch, the final launch for the GOES-R Series. GOES-U completed mechanical environments testing and will next undergo electromagnetic interference/electromagnetic compatibility testing. We held our first GOES-R summit since 2019 and had the opportunity to collaborate in person with our colleagues from across the country. The newly operational GOES-18 satellite monitored a deluge of atmospheric rivers affecting the West Coast and an increasingly active sun. On GeoXO, we took our first step into implementation, with the award of the development contract for the imager, the primary instrument on our next-generation satellite system.
Beginning on March 24, 2023, NOAA satellites monitored severe storms that caused widespread damage from Texas to the Mid-Atlantic. The storms produced high winds, hail, flooding, and tornadoes. High winds and 38 tornadoes were reported when the storms moved through Mississippi, Alabama and Tennessee. The town of Rolling Fork, Mississippi was struck by an EF-4 tornado that killed 26 people in total, injured dozens more, and damaged buildings and utilities. GOES-16 (GOES East) monitored the storm in near real-time as it barreled across the Southeast.
After tracking a series of atmospheric rivers that have drenched California this year, NOAA satellites monitored the latest storm to begin impact the state on Mar. 19, 2023. Rain and snow triggered flash flooding, caused numerous evacuations and left over 350,000 without power. The atmospheric river fueled a mid-latitude cyclone that led to the formation of a hurricane-like eye when two low pressure areas converged over San Francisco. NOAA satellites provided vital information about airborne moisture for more accurate weather forecasts and to predict flood risks and manage water resources.
Since mid-February 2023, winter weather has impacted the continental U.S. from California to Maine. In Southern California, the storm brought blizzard conditions to the San Bernardino and San Gabriel mountains as well as heavy rainfall to lower elevations. As the storm system continued eastward, snow and driving winds caused road closures and drifting snow across the Plains. Further south in Kansas and Oklahoma, tornadoes downed power lines, damaged property, and caused injuries. Additional tornadoes were reported in central and northeastern Illinois. The storm also brought heavy snow to the Northeast. NOAA satellites provided complementary measurements for a complete picture of this monumental storm and played a crucial role in tracking the storms across the U.S., alerting those in harm’s way.
On Feb. 21, 2023, Tropical Cyclone Freddy made landfall on Madagascar. Freddy formed on Feb. 5 near Indonesia and trekked more than 4,000 miles before hitting Madagascar. Freddy is one of only four storms on record to cross the Indian Ocean from east to west. It is also the first in the Southern Hemisphere to undergo four separate rounds of rapid intensification. At its strongest, Freddy had maximum sustained winds of more than 160 miles per hour, equivalent to a Category 5 hurricane. NOAA satellites and those from our international partners monitored the storm as it traversed the Indian Ocean and made landfall in Madagascar.
At least 231 wildfires have been blazing through south-central Chile since Feb. 3, 2023. The region is experiencing a “mega drought” with a decade-long period of dry weather. NOAA satellites are monitoring the fires as hot and dry weather persists. As of Feb. 8, 231 fires have burned more than 741,315 acres of land, making it the second worst year for acreage burned in Chile. GOES-16 and GOES-18 observed the movement of smoke from the fires in near-real time, while identifying new fires. The satellites also help determine a fire’s size and temperature. NOAA-20 and Suomi NPP provide detailed information on fire conditions. The satellites can detect smaller and lower-temperature fires and track wildfires in remote regions. Together, NOAA satellites provide critical and timely information used by fire crews, first responders and air traffic controllers.

On Jan. 25, 2023, NOAA satellites captured an unusually long and long-lived rope cloud produced by a cold front over the Gulf of Mexico. A rope cloud is a very long, narrow, rope-like band of cumulus cloud formations. Generally associated with a cold front or a land-sea breeze front, rope clouds tend to form at the dividing line between cooler and warmer air. In this case, the rush of cool, dense air from the cold front pushed the warm, maritime air from the Gulf of Mexico upward, allowing water vapor to condense and the cloud to form. Satellite imagery can capture rope clouds, indicating a potentially changing weather pattern.
From late Dec. 2022 into Jan. 2023, a series of nine “atmospheric rivers” dumped a record amount of rain and mountain snow across the western U.S. and Canada, hitting California particularly hard. More than 32 trillion gallons of water rained down across the state, and the moisture also pushed into much of the Intermountain West. The San Francisco Bay area experienced its wettest three-week period in 161 years. Atmospheric rivers are long, narrow belts of moisture that move through the atmosphere. They can deliver tremendous amounts of rain, and high-elevation snow. This deluge of rain can provide relief for drought-stricken areas but also trigger flash flooding and mudslides. NOAA satellites help forecast these rivers in the sky and monitor the weather conditions they bring.
NOAA satellites, which are crucial in weather and climate forecasts, helped rescue 397 people from potentially life-threatening situations throughout the U.S. and its surrounding waters in 2022. NOAA’s polar-orbiting and geostationary satellites are part of the global Search and Rescue Satellite Aided Tracking system, or COSPAS-SARSAT, which uses a network of U.S. and international spacecraft to detect and locate distress signals sent from emergency beacons from aircraft, boats and handheld Personal Locator Beacons (PLBs) anywhere in the world. Of the 397 U.S. rescues last year, 275 were water rescues, 42 were from downed aircraft and 80 were on land involving PLBs. Florida had the most SARSAT rescues with 106, followed by Alaska with 56 and Utah with 20.
The GOES-R/GeoXO quarterly newsletter for October – December 2022 is now available. The GOES-R and GeoXO programs achieved new heights in 2022. We launched GOES-T, now known as GOES-18, completed on-orbit checkout, executed two GOES-17 and GOES-18 data interleave periods, and handed the satellite over to NOAA’s Office of Satellite and Product Operations. GOES-18 became NOAA’s operational GOES West satellite on Jan. 4, 2023. GOES-U is progressing toward its planned launch next spring, completing thermal vacuum testing and preparing for mechanical testing. And the future of NOAA’s geostationary satellite observations is assured, with the approval of the GeoXO Program.
NOAA’s operational satellite fleet has a new member. GOES-18 entered service as GOES West on Jan. 4, 2023. The milestone comes after a Mar. 1, 2022, launch and post-launch testing of the satellite’s instruments, systems, and data. GOES-18 replaces GOES-17 as GOES West, located 22,236 miles above the equator over the Pacific Ocean. GOES-17 will become an on-orbit standby. In its new role, GOES-18 will serve as NOAA's primary geostationary satellite for detecting and monitoring Pacific hurricanes, atmospheric rivers, coastal fog, wildfires, volcanic eruptions, and other environmental phenomena that affect the western contiguous United States, Alaska, Hawaii, Mexico, and Central America. GOES-18 joins GOES-16 (GOES East) in operational service. Together the two satellites watch over more than half the globe, from the west coast of Africa to New Zealand and from near the Arctic Circle to the Antarctic Circle.
NOAA satellites see our planet from a unique and captivating perspective. Every year, our satellites see the beauty and wrath of Mother Nature unfold beneath them—devastating hurricanes, raging wildfires, erupting volcanoes—as well as the changing seasons, ocean color and nighttime lights. And their scope isn’t just limited to Earth; NOAA satellites can also capture images of our Moon and the Sun as we all spin our way through our place in space. View NOAA’s list of most compelling images from 2022 as seen from orbit by NOAA’s satellites.
On Nov. 28, 2022, the Mauna Loa volcano, located on Hawaii’s Big Island, began erupting for the first time since 1984. The volcano began spewing ash and debris from its summit after a series of earthquakes and lava was ejected to heights of up to 148 feet on Nov. 29. As of Dec. 6, The Northeast Rift Zone eruption continued, with an active fissure feeding lava flow downslope. NOAA satellites monitored the ongoing eruption, lava flow, ash plume, and sulfur dioxide emissions. Mauna Loa has erupted 33 times since 1893, making it the world’s most active volcano. NOAA satellites are critical for detecting volcanic activity, alerting those in harm’s way of an eruption, and monitoring the hazards associated with volcanic eruptions.
The 2022 Atlantic hurricane season officially came to a close on Nov. 30. This season produced 14 named storms, of which eight became hurricanes and two intensified to major hurricanes. This season was also defined by a rare mid-season pause in storms that scientists believe was preliminarily caused by increased wind shear and suppressed atmospheric moisture high over the Atlantic Ocean. After a quiet period in August, activity ramped up in September with seven named storms, including the two major hurricanes — Fiona and Ian — seen this season. The season also included a rare late-season storm with Hurricane Nicole making landfall on November 10 along the east coast of Florida. NOAA satellites constantly monitor the Atlantic hurricane basin and provided valuable data and imagery to forecasters for tracking the development, movement, and intensity of tropical cyclones this season.
NOAA’s GOES-U, the final satellite in the GOES-R Series of advanced geostationary environmental satellites, recently completed thermal vacuum (TVAC) testing as part of a rigorous assessment program to ensure the satellite can withstand the harsh conditions of launch and orbiting 22,236 miles above Earth’s equator. The testing is taking place at Lockheed Martin Space’s Littleton, Colorado, facility, where GOES-U was built. GOES-U will undergo additional testing in the coming months to prepare for a planned April 2024 launch. Learn more about the testing and a new instrument that will fly on GOES-U, the Compact Coronagraph.

As cooler temperatures descend across parts of North America, NOAA satellites observed fires erupting in the Pacific Northwest this month. Warm, dry and windy conditions brought some of the driest October weather conditions to the region, increasing the risk of wildfires. Since Jan. 1, 2022, 56,710 wildfires have burned 7,022,627 acres around the country. This is the most wildfires reported to date in the past 10 years. Currently, there are more than 333,213 acres burning across Oregon, the largest total area of any state. NOAA satellites provide potentially life-saving information in a dynamic fire environment. GOES East and GOES West frequently detect fires before they are spotted on the ground, which is particularly important in remote areas. The satellites also track fires in real time, identify and track smoke, and determine a fire’s size and temperature. Suomi-NPP and NOAA-20 detect smaller and lower-temperature fires and also provide nighttime fire detection. The data from these satellites is also critical to smoke models used by fire crews, first responders, and air traffic controllers. As conditions remain warm and dry, NOAA satellites remain on watch for wildfires.
The GOES-R/GeoXO quarterly newsletter for July – September 2022 is now available. Congratulations to the team for completing GOES-18 post-launch testing and preparing the satellite for early operations! Our mission operations team completed a successful GOES-17/18 “interleave” period, delivering operational GOES-18 Advanced Baseline Imager (ABI) data to forecasters during the “warm” periods that degrade some GOES-17 (GOES West) imagery. GOES West data users have expressed appreciation for this novel solution to get them the GOES-18 ABI data early and shared how it has helped them with forecasts and warnings. GOES-18 has been handed over to NOAA’S Office of Satellite and Product Operations, and after additional product testing, it will go into operational service as GOES West in January 2023. GOES-U is fully integrated and beginning environmental testing. And GeoXO is moving full steam ahead toward Milestone 2 after completing the System Requirements Review in August. Our team continues to meet the mission and deliver life-saving technology and science to the nation.
On Sept. 28, Hurricane Ian made landfall near Cayo Costa in southwestern Florida as a dangerous Category 4 storm after plowing a path of destruction through the Caribbean, bringing particularly heavy rainfall and dangerous surf to Jamaica, the Cayman Islands, and western Cuba. Ian thrashed parts of Florida’s western coast, bringing intense winds, heavy rainfall, and catastrophic storm surge. After crossing over the Florida peninsula, where it had weakened to a tropical storm, Ian strengthened again over the Atlantic to a Category 1 hurricane and made a second landfall near Georgetown, South Carolina on Sept. 30. NOAA satellite imagery helped forecasters pinpoint the center of circulation in real-time, monitor the storm’s intensity and movement, track thunderstorm activity both in the eyewall and in the tornado-producing outer rain bands, and determine when landfall would occur.
Hurricane Fiona, the first major storm of the Atlantic hurricane season, has been wreaking havoc, causing catastrophic damage across Puerto Rico, the Dominican Republic, and Turks and Caicos. The storm has caused devastating flooding and has damaged critical water and power infrastructure in its wake. Now, with sustained wind speeds of near 130 mph, Fiona is heading northward toward Bermuda as a Category 4 hurricane. NOAA satellites provide vital information for forecasting hurricanes and monitoring the location, movement and intensity of storms. As Fiona continues on its path, and other storms develop, NOAA satellites will be watching.
NOAA satellites have tracked a lot of activity across western North America this month. From wildfires, to a hurricane, to heavy rains in the drought-stricken region, satellite imagery has been vital in monitoring these events. Pacific moisture from Hurricane Kay brought heavy rain and flash flooding to areas in California and Arizona. The remnants of Kay provided temporary relief to some communities battling wildfires. Meanwhile, the Northwest continued to experience dry conditions and wildfires. No matter what phenomena occur, NOAA satellites provide critical data for monitoring hazardous situations.
Did you know that most people who have space-related careers are not astronauts or rocket scientists? Space missions, satellite programs, and scientific research require a large team of people with a variety of skills. NOAA spoke to a few team members about their space-related careers and the advice they’d give to young people reaching for the stars, including GOES-R/GeoXO Chief of Staff Kevin Fryar.
After a slow start to the 2022 Atlantic hurricane season, activity has ramped up with the first two hurricanes forming during the first week of September. The Atlantic went without a named from July 6 through Aug. 31. August passed without a named storm for the first time since 1997. Tropical Storm Danielle formed on Sept. 1 in the far North Atlantic. The storm gained strength unusually far north where hurricanes are rare. Record-warm ocean temperatures fueled Danielle, which strengthened into a hurricane on Sept. 2. Tropical Storm Earl developed east of the Northern Leeward Islands on Sept. 3, and brought heavy rains to Puerto Rico, the U.S. Virgin Islands and the Leeward Islands. Earl strengthened to hurricane status on the evening of Sept. 6 and is expected to pass southeast of Bermuda late on Sept. 8. NOAA satellites monitor the ocean and atmospheric conditions that lead to the development of tropical storms and hurricanes. Once a storm forms, the satellites provide critical data—such as location, movement, and intensity—to track the storms.
Aug. 24, 2022, marked the 30th anniversary of Hurricane Andrew’s landfall in southern Florida. Andrew was one of the most catastrophic hurricanes in U.S. history. Since Hurricane Andrew, dramatic advancements in technology have helped to better prepare for, predict, monitor, and respond to hurricanes. NOAA’s latest generation of satellites has revolutionized the way scientists and forecasters monitor and track tropical systems. They monitor the conditions that lead to hurricane formation, provide early warning that a storm is forming, monitor and track the movement of storms, and estimate storm intensity. NOAA satellites are our vigilant eyes in the sky, helping protect lives and property when hurricanes strike.
Lightning is a major public safety threat. Several incidents of injuries and fatalities from lightning strikes in early August 2022 highlight the importance of lightning safety and awareness. The GOES-R Geostationary Lightning Mapper (GLM) detects and maps lightning within storms. GLM can show forecasters areas where the risk of lightning strikes presents a public safety hazard, leading to fewer lightning-related injuries and deaths. GOES-16 and GOES-17 can not only detect current lightning activity, but their data can also help predict the occurrence of lightning in the future. Scientists are using an artificial intelligence (AI) model, called ProbSevere LightningCast to predict where lightning is most likely to occur up to 60 minutes in advance. As thunderstorms occur with a threat of lightning, NOAA satellites work with partners and decision-makers to keep the public safe and informed.
Hundreds of miles apart, but connected by the same weather system, urban St. Louis and rural Appalachia have recently experienced devastating flash flooding. NOAA satellites monitored the storms that produced the catastrophic flooding, measuring the amount of water vapor in the atmosphere, cloud top temperatures, and lightning activity. Scientists also use data collected NOAA satellites to produce flood maps to determine where flooding may be occurring. These maps help first responders decide where to send aid. When storm systems develop with the potential to cause flash flooding, NOAA satellites will be watching.
Strong winds and extremely dry conditions fueled a wildfire that ignited on July 22 near Yosemite National Park. The Oak Fire is currently the largest active wildfire in California, burning more than 18,800 acres. NOAA satellites are monitoring the rapidly spreading fire and providing critical data. GOES-17 is measuring the Oak Fire’s intensity, tracking its spread, and monitoring the movement of smoke in near real-time. As drought persists, and fire season ramps up, NOAA satellites will be watching and providing timely and potentially life-saving information.
While NOAA’s GOES-18 undergoes post-launch testing (PLT) and calibration of its instruments and systems, the new satellite is in position to help forecasters during the height of the 2022 Pacific hurricane season. GOES-18 was moved to 137.0 degrees west longitude early in PLT so its Advanced Baseline Imager (ABI) data will be available to forecasters during the “warm” periods that degrade some GOES-17 (GOES-West) imagery during the height of hurricane season. NOAA implemented a unique solution to mitigate the loss of warm period GOES-17 imagery by delivering GOES-18 ABI data to GOES-West data users. Starting on Aug. 1, 2022, GOES-West data users will receive GOES-18 ABI data for operational use. This will be accomplished through a data “interleave” that will deliver GOES-18 ABI data with GOES-17 lightning mapper and space weather data through the GOES Rebroadcast and Product Distribution and Access data delivery systems. This period of data interleave will end on Sept. 6. A second period of data interleave will take place from Oct. 13 through Nov. 14 of this year.
The Solar Ultraviolet Imager, or SUVI, onboard NOAA’s GOES-18 satellite, which launched on March 1, 2022, began observing the sun on June 24, 2022. The sun’s 11-year activity cycle is ramping back up, meaning phenomena such as coronal mass ejections (CMEs) and solar flares are increasing in frequency. GOES-18’s SUVI captured a CME on July 10, 2022. SUVI monitors the sun in the extreme ultraviolet portion of the electromagnetic spectrum. Depending on the size and the trajectory of solar eruptions, the possible effects to near-Earth space and Earth’s magnetosphere can cause geomagnetic storms, which can disrupt power utilities and communication and navigation systems. These storms may also cause radiation damage to orbiting satellites and the International Space Station.
The Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS) onboard NOAA’s GOES-18 satellite are powered on, performing well, and observing the sun. On July 5, 2022, EXIS observed a pair of moderate flares that erupted on the sun between 3:30 and 4:30 UTC. EXIS has two main sensors, the X-Ray Sensor (XRS), which measures soft X-rays, and the Extreme Ultraviolet Sensors (EUVS), which measure extreme ultraviolet light. The two flares appeared differently near Earth and demonstrate why EXIS observes light from the sun at multiple wavelengths. EXIS, with its multiple sensors, can observe and quantify the difference between the light from solar flares and help determine in real-time whether the flares will affect us on Earth.
The GOES-R/GeoXO quarterly newsletter for April – June 2022 is now available. GOES-18 is doing well in post-launch testing, with the first imagery released from four of its instruments. GOES-18 is now operating near the GOES-West location, getting ready to provide operational Advanced Baseline Imager (ABI) data to forecasters during the GOES-17 warm period outages. The team did an excellent job making the novel ABI ‘interleave’ and cloud delivery techniques possible. GOES-U is also making great progress, with the System Integration Review complete, and Pre-Environmental Review happening in mid-July. GeoXO is ever more active, with Phase A studies awarded for three more instruments, and preparations in high gear for the System Requirements Review in August.
Lightning can be a beautiful—and scary—part of Earth’s weather. You probably have seen lightning in a thunderstorm, but do you know why lightning happens? Learn more in this new video from NOAA SciJinks.
Throughout June 2022, NOAA satellites monitored wildfires in Alaska that have burned more than 1.6 million acres. Unusually hot and dry weather in the region increased the risk of fires. These conditions led to more than 300 fires in recent weeks, with many sparked by lightning. On May 31, lightning ignited the East Fork Fire and burned over 250,000 acres, making it one of the largest tundra fires on record. Meanwhile, the Lime Complex Fire has burned more than 600,000 acres in southwestern Alaska. As Alaska’s historic wildfire season continues, NOAA satellites are keeping watch.
June 21 marked the official start of astronomical summer in the Northern Hemisphere. The summer solstice — the longest day and shortest night of the year — occurred at 5:14 a.m. EDT. The summer solstice is the moment the hemisphere reaches its greatest tilt toward the sun. As the Earth rotates on its axis, the North Pole experiences 24 hours of daylight, while the South Pole is obscured in darkness. NOAA’s GOES-16 and GOES-17 satellites constantly observe the same region of Earth, allowing a view of the terminator as it moves across the Western Hemisphere. The terminator is the edge between the shadows of nightfall and the sunlight of dusk and dawn. The slope of the terminator curve changes with the seasons.
NOAA’s GOES-18 is now sending back data from its new post-launch testing position over the Pacific Ocean. From its new vantage point, GOES-18 can now see Alaska, Hawaii, and the Pacific Ocean all the way to New Zealand. This location allows it to monitor the northeastern Pacific, where many of the weather systems affecting the continental U.S. originate. GOES-18 has already seen a lot from its new location. Recently, the GOES-18 Advanced Baseline Imager (ABI) monitored a number of weather events, meteorological phenomena, and environmental hazards. The satellite tracked fire activity in Alaska, snow and the movement of fog and smoke. It monitored a low pressure system off the West Coast and severe thunderstorms in Colorado. GOES-18 also viewed mesmerizing von Kármán vortices off the coast of Isla Guadalupe and beautiful cloud formations over Hawaii. As GOES-18 continues post-launch testing, its ABI will provide critical information for eastern Pacific hurricane forecasters despite not yet being fully operational. After the completion of post-launch testing and checkout, NOAA plans for GOES-18 to replace GOES-17 as the operational GOES West satellite in early 2023.
The 2022 hurricane season is officially underway. The eastern Pacific hurricane season began on May 15, while June 1 marked the beginning of the Atlantic hurricane season. NOAA satellites monitored the first named storms in each hurricane basin. Tropical Storm Agatha formed in the eastern Pacific Ocean on May 28 and rapidly intensified into a Category 2 hurricane. On May 30, Agatha became the strongest hurricane on record to make landfall along the Pacific coast of Mexico in the month of May. Remnants from Agatha helped fuel what would become the Atlantic’s first named tropical storm, Alex, which affected south Florida at the beginning of June. NOAA satellites provide vital information for forecasting hurricanes and monitoring the location, movement and intensity of storms. As the hurricane season ramps up, NOAA satellites are keeping watch.
A team of scientists from NOAA’s Satellite and Information Service (NESDIS) and South Dakota State University has developed more accurate forecasts to predict the impacts of wildfire smoke on air quality. The method known as Regional Hourly Advanced Baseline Imager (ABI) and Visible Infrared Imaging Radiometer Suite (VIIRS) Emissions, or RAVE, combines observations from instruments on NOAA’s geostationary and polar-orbiting weather satellites to calculate estimates of wildfire emissions.
On June 2, NOAA shared striking first imagery from the GOES-18 Geostationary Lightning Mapper (GLM). Recently, GLM monitored lightning activity within severe storms across the U.S. The instrument captured significant lightning activity in the derecho that moved across the Northern Plains on May 12-13. GLM helps forecasters identify intensifying storms and captures the evolution of individual storm cells that combine to form massive storm systems. Widespread weather events pose particular challenges for the aviation industry. GLM data helps pilots and air traffic controllers route flights to maximize safety and minimize economic impacts. GOES-18 is undergoing post-launch testing to prepare it for operations. NOAA plans for GOES-18 to begin operating as GOES West in early 2023.
Winners of the 2022 GOES-16/17 Virtual Science Fair were announced on June 1. In this nationwide virtual science competition, students designed projects that used GOES 16/17 satellite data to investigate weather or natural hazards. Each individual/team shared their project through a scientific poster and a short video presentation. The winning high school project, by Rebecca Liftik of Sandy Spring Friends School in Sandy Spring, Maryland, examined pyrocumulonimbus clouds in the 2021 Bootleg Fire using GOES-17 data. The winning middle school project, from Eric Sun and Sean Jiang of Gilman Middle School in Baltimore, Maryland, studied the causes of the 2021 California wildfires using GOES-17 data.
On May 11, 2022, NOAA shared the first images of the Western Hemisphere from its GOES-18 satellite. The satellite’s Advanced Baseline Imager (ABI) instrument recently observed a number of weather events, environmental phenomena, and striking views of Earth. Storms across east Texas produced large hail, strong wind gusts, and tornadoes. Farther west in New Mexico, strong winds resulted in large areas of blowing dust and expansion of large wildfires. Fog blanketed parts of Chile in South America, and clouds and some thunderstorms formed along sea breezes in the Yucatan and south Florida. GOES-18, launched on March 1, 2022, is currently undergoing post-launch testing in preparation for transitioning to operations as GOES West in early 2023.
The Goddard Magnetometer (GMAG) instrument, launched aboard NOAA’s GOES-18 satellite on March 1, 2022, is now transmitting magnetic field measurements down to Earth. On April 27, 2022, the GOES-18 GMAG captured a space weather phenomenon known as plasma waves. These waves play a significant role in controlling the levels of dangerous energetic particles that cause damage to satellites and harm astronauts. The GOES-18 GMAG is an upgraded magnetometer instrument that offers improved measurements of Earth’s magnetic field over the magnetometers on GOES-16 and GOES-17.
The Space Environment In-Situ Suite (SEISS) instrument onboard NOAA's GOES-18 satellite is now sending radiation data back to Earth. GOES-18 launched on March 1, 2022, and the SEISS sensors have been collecting data continuously since April 25, 2022. The GOES-18 SEISS detected a number of radiation belt disturbances on April 27-29, 2022. Shortly after these observations were seen by the GOES-18 SEISS, NOAA’s Space Weather Prediction Center (SWPC) issued an alert for a G1 (minor) geomagnetic storm, warning of possible risk to satellite systems due to charging.
Since early April 2022, NOAA satellites have been watching wildfires burning across parts of the Southwest and Plains. The two largest fires located in northern New Mexico, the Calf Canyon and Hermits Peak Fires, have burned more than 60,000 acres. GOES-17 watched smoke billowing over the region and drifting to areas upwind bringing hazy skies to communities many miles away. GOES-17 and GOES-16 also detected hot spots from the fires in near-real time while providing information on the size and intensity of these fires. NOAA-20 and Suomi NPP captured daytime and nighttime images of the fires. They also took air quality measurements and tracked the movement and thickness of smoke over the region. As fire season starts earlier and ends later, NOAA satellites are keeping watch.
Before we had satellites, we could only imagine what the Earth looked like from above. Our view has come a long way, from changes in technology to how we understand Earth’s systems. Built upon NASA’s pioneering efforts, NOAA’s satellite program continues to improve Earth observations from space. Since 1970, NOAA satellites have monitored Earth's weather, environment, oceans and climate. As NOAA satellites continue to advance, they increase our understanding our planet, because every day at NOAA is Earth Day.
This week, NOAA satellites monitored a large storm system that brought winter weather to some regions and severe weather to others. GOES-17 watched as the system moved eastward across the Pacific Northwest where it brought snow. GOES-16 watched the progression of the storm as the cold air met with the warm humid air from the Gulf of Mexico. This clash of air masses led to severe weather in multiple states across the Midwest and South. The GOES-16 Geostationary Lightning Mapper watched as the storms produced frequent lightning as they marched eastward. The system produced more than 500 reports of damaging winds, large hail, and tornadoes throughout the central U.S. The storms finally wound down as the system reached the East Coast.
The GOES-R/GeoXO quarterly newsletter for January – March 2022 is now available. Congratulations to the team on another successful launch! GOES-T lifted off on March 1, 2022, four years to the day after GOES-S launched. The satellite reached geostationary orbit on March 14 and is now GOES-18. Post-launch testing is now underway and GOES-18 is expected to take its place as the operational GOES West satellite in early 2023. Getting GOES-18 into orbit was a remarkable feat amid the COVID-19 pandemic. Looking forward, the team is busy with GOES-U integration and testing in preparation for launch in 2024 and progressing through GeoXO Phase A activities toward Milestone 2 later this year.
The vernal equinox on March 20, 2022, marked the beginning of astronomical spring in the Northern Hemisphere. The spring equinox results in nearly equal daylight and darkness across the planet. During an equinox, the terminator – the edge between the shadows of nightfall and the sunlight of dusk and dawn – is a straight north-south line over the equator. GOES-16 and GOES-17 constantly observe the same region of Earth, allowing a view of the terminator as it moves across the Western Hemisphere. Earth’s seasons change due to the tilt of the planet’s axis as it orbits the sun. Throughout the year, these satellites observe the markers of seasonal change.
On March 14, 2022, GOES-T executed its final engine burn, placing the satellite in geostationary orbit 22,236 miles above Earth. Upon reaching this milestone, GOES-T was renamed GOES-18. NOAA’s GOES-T satellite launched on March 1, 2022, at 4:38 p.m. EST, lifting off from Cape Canaveral Space Force Station in Florida. The satellite launched aboard a United Launch Alliance Atlas V rocket from Space Launch Complex 41. The launch was managed by NASA’s Launch Services Program, based at Kennedy Space Center.
NOAA’s GOES-T, the third in a series of four advanced geostationary weather satellites, blasted into orbit aboard a United Launch Alliance Atlas V 541 rocket at 4:38 p.m. ET today from Cape Canaveral, Florida. After a successful separation from the Centaur upper stage, GOES-T began flying freely. Shortly after, the satellite completed deployment of the stage 1 solar array that will generate electricity for the spacecraft during its mission. GOES-T is orbiting above the Earth, its systems are in good health and it is operating on its own.
GOES-T lifted off from Space Launch Complex-41 at Cape Canaveral Space Force Station, Florida, on March 1, 2022, at the opening of the launch window at 4:38 p.m. EST. The spacecraft separated from the Centaur upper stage at 8:11 p.m. EST and first stage solar array deployment occurred at 8:28, with power positive confirmed.

GOES-T will provide critical data for identifying and tracking environmental hazards of particular concern to the western U.S. GOES-T will locate wildfire hot spots, detect changes in fire behavior, predict the motion of fires, estimate a fire’s intensity, and monitor smoke output and air quality effects from smoke. GOES-T can identify the lightning strikes most likely to ignite fires and characterize pyrocumulonimbus clouds that threaten the safety of firefighters.
The GOES-T satellite is now encapsulated the Atlas V fairing. The payload fairing is a specially designed nose cone that, in addition to creating a more aerodynamic profile, encapsulates the satellite, protecting it during the ascent through Earth's atmosphere after launch. GOES-T will soon be moved to Space Launch Complex 41 at Cape Canaveral Space Force Station for mounting atop the Atlas V rocket that will boost the satellite to orbit. Additional photos are available in the GOES-T Road to Launch gallery.
The United Launch Alliance (ULA) Centaur upper stage was placed atop the Atlas V booster in the Vertical Integration Facility (VIF) adjacent to Space Launch Complex-41 at Cape Canaveral Space Force Station on Feb. 7, 2022. The Centaur is the launch vehicle’s “brain,” providing guidance and flight control and containing fuel and oxidizer to insert the vehicle into orbit. Additional photos are available in the GOES-T Road to Launch gallery.
Last month, we challenged kids to draw the GOES-T satellite observing the weather during this time of year where they live. From the hundreds of submissions, we selected 25 to feature.
A cutting-edge new instrument is ready to be installed on NOAA’s GOES-U satellite, which is scheduled to launch in 2024. The Compact Coronagraph-1 (CCOR-1) instrument was shipped to Lockheed Martin in Waterton, Colorado, after passing its Pre-Shipment Review last month. The team at Lockheed Martin will now begin to install this instrument onto the GOES-U spacecraft. The CCOR-1 will be NOAA’s first-ever solar coronagraph.
Fog and low stratus clouds over airports can create dangerous travel conditions that result in costly delays and disrupted travel plans. The U.S. National Weather Service offices monitor and issue warnings when conditions are favorable for the formation of fog and low-level clouds. These warnings are used by the airlines to anticipate conditions, avoid delays and reroute flights if necessary. Now, the NWS uses a new fog detection software developed by scientists at the University of Wisconsin-Madison Cooperative Institute for Meteorological Satellite Studies and NOAA to assist with those warnings. The software uses machine learning techniques with near real-time data from weather satellites like NOAA’s GOES-East and GOES-West to monitor conditions 24/7 and issue potential fog warnings.
The World Meteorological Organization (WMO) has established two new world records for megaflashes of lightning in notorious hotspots in North and South America. Aided by the latest satellite technology from the GOES-R Series Geostationary Lightning Mapper (GLM), the WMO recognized the longest distance of a single flash and the greatest duration for a single flash. On April 29, 2020, a mass of severe thunderstorms produced a 477.2-mile-long lightning strike over the southern United States. It stretched from near Houston to southeast Mississippi. The WMO also identified a new world record for the long-lasting lightning flash that lasted for 17.1 seconds over Uruguay and northern Argentina for 17.1 seconds on June 18, 2020. The GLM offers the unique ability to measure lightning flash extent and duration continuously over broad areas.
The United Launch Alliance (ULA) rocket that will launch GOES-T into space was placed on its stand in the Vertical Integration Facility (VIF) adjacent to Space Launch Complex-41 at Cape Canaveral Space Force Station on Jan. 31, 2022. The Atlas V first stage booster is the backbone of the launch vehicle. It holds the fuel and oxygen tanks that feed the engine for powering the spacecraft into orbit. View additional photos in the GOES-T Road to Launch image gallery.
NOAA’s fleet of advanced satellites are essential for predicting weather and climate, and last year they also helped rescue 330 people from potentially life-threatening situations throughout the United States and its surrounding waters. NOAA’s polar-orbiting and geostationary satellites are part of the global Search and Rescue Satellite Aided Tracking system, or COSPAS-SARSAT, which uses a network of U.S. and international spacecraft to detect and locate distress signals sent from emergency beacons from aircraft, boats and handheld Personal Locator Beacons (PLBs) anywhere in the world. Since its start in 1982, COSPAS-SARSAT has been credited with supporting more than 48,000 rescues worldwide, including more than 9,700 in the United States and its surrounding waters.
On Jan. 15, 2022 an underwater volcano in the South Pacific Kingdom of Tonga exploded violently in what was likely the largest recorded eruption on Earth in decades. The eruption generated atmospheric shock waves, sonic booms, and tsunami waves that traveled the world and were heard as far away as Alaska. Satellites operated by NOAA and its international partners play a crucial role in detecting volcanic activity, alerting those in harm’s way of an eruption, and monitoring the hazards associated with volcanic eruptions, including volcanic ash and tsunamis.
Experts from NOAA, NASA, United Launch Alliance, Lockheed Martin and L3Harris will hold a virtual media briefing on February 1, 2022, to preview the upcoming launch and mission of NOAA’s GOES-T, the third in a series of four advanced geostationary weather satellites.
On January 1, 2022, there were numerous reports of sonic booms in southwestern Pennsylvania. GOES-16’s Geostationary Lightning Mapper (GLM) picked up a large flash that wasn’t associated with a thunderstorm. GLM data indicated the source of the mysterious sound to be a bolide, or large meteor exploding in the atmosphere. The GLM onboard GOES-16 and GOES-17 primarily monitors lightning activity. However, it can also detect bolides, and has captured many of these exploding meteors. Loud booms with no visible source can cause a lot of anxiety – especially in populated areas. When GLM is able to quickly confirm the presence of a bolide, it helps calm fears. GLM constantly keeps watch for both lightning and exploding meteor hazards.
The GOES-R/GeoXO quarterly newsletter for October – December 2021 is now available. Goodbye to 2021, a challenging year, which did not at all deter the GOES-R/GeoXO team. Our team continues to accomplish outstanding things—achievements made even more impressive because of the pandemic. In the last quarter of the year alone, we delivered GOES-T to Florida and began readying it for a March 1 launch, executed a number of ground system and mission operations rehearsals and tests to prepare for the GOES-T launch, got the brand-new CCOR instrument through thermal vacuuming testing, received approval to formally initiate the GeoXO Program and received concurrence on proposed program and project acquisition strategies. We can’t wait to see GOES-T on-orbit and GeoXO fully in Phase A.
On March 1, 2022, the United States will be launching its latest weather satellite, called GOES-T. GOES-T is part of a group of NOAA satellites that keep an eye on Earth’s weather from space. Why do we need these weather satellites? The information they collect is used in many ways! In fact, if you’ve ever checked a weather forecast on a phone, computer or television, you’ve used information collected by one of GOES-T’s satellite sisters.
Challenge: Draw the GOES-T satellite observing the typical weather during this time of year where you live! Is it snowy and cold? Is it sunny and warm? Are there storms or lightning?
Need some inspiration? Check out this video and comic book to learn more about weather satellites like GOES-T!
The art challenge is open through Jan. 31. Selected art submissions will appear online and in social media the first week of February.
