August 8, 2019: NOAA Increases Chance for Above-Normal Hurricane Season

NOAA forecasters monitoring oceanic and atmospheric patterns say conditions are now more favorable for above-normal hurricane activity since El Nino has now ended. Two named storms have formed so far this year and the peak months of the hurricane season, August through October, are now underway. Seasonal forecasters with NOAA’s Climate Prediction Center have increased the likelihood of an above-normal Atlantic hurricane season to 45% (up from 30% from the outlook issued in May). The likelihood of near-normal activity is now at 35%, and the chance of below-normal activity has dropped to 20%. The number of predicted storms is also greater with NOAA now expecting 10-17 named storms (winds of 39 mph or greater), of which 5-9 will become hurricanes (winds of 74 mph or greater), including 2-4 major hurricanes (winds of 111 mph or greater).

Learn how hurricanes form and how GOES-R satellites can help predict a storm's intensity and track it minute-by-minute. This information allows meteorologists to deliver early warnings and help people stay safe.

August 2, 2019: NOAA Science on a Sphere Explorer Mobile App

A new NOAA app brings earth and space animations to your phone. NOAA's SOS Explorer™ Mobile, an app for personal mobile devices, tells earth science stories by playing visually stunning data animations on a virtual globe. SOSx Mobile offers more than 115 datasets from NOAA, NASA, and academic institutions, including: Climate models predicting Earth’s temperature through 2100 for different greenhouse gas emissions scenarios; National Marine Sanctuaries’ 360-degree underwater photographs in the Florida Keys; and the entire 2017 hurricane season, including Hurricanes Irma and Maria, as captured by NOAA weather satellites.

July 30, 2019: Wildfires from Space: How the View from Above Helps Firefighters on the Ground

Firefighters do the heavy lifting when it comes to fighting and managing wildfires, but they’re often helped by the view from above, thanks to coordinated satellite observations and high-flying airplanes. A large global constellation of satellites, operated by NASA and National Oceanic and Atmospheric Administration (NOAA), combined with a small fleet of planes operated by the U.S. Forest Service (USFS) help detect and map the extent, spread and impact of forest fires. GOES-16 and GOES-17 aid this effort, often spotting fires before they are reported on the ground.

July 22, 2019: Where There’s Fire, There’s Smoke — and Secrets for Science to Uncover

Extreme wildfire seasons are no longer an outlier in the western United States, where climate change is drying out vegetation and people are moving deeper and deeper into western forests. All that fire produces a lot of smoke — and a serious air pollution problem. This summer, NOAA and NASA are teaming up on a massive research campaign called FIREX-AQ that will use satellites (including GOES-16 and GOES-17), aircraft, drones, mobile and ground stations to study smoke from wildfires and agricultural crop fires across the U.S. Hundreds of scientists will explore the chemistry of trace gases and aerosols in smoke to uncover its secrets, improve weather and air quality models, and provide better forecasts to first responders, public health and land management officials.

July 15, 2019: 2nd Quarter 2019 GOES-R Program Newsletter

The GOES-R Series Program quarterly newsletter for April – June 2019 is now available. GOES-16 and GOES-17 continue to provide high definition imagery to forecasters, monitoring Hurricane Barry as it came ashore near New Orleans, viewing the first eruption of the Raikoke volcano in the northwest Pacific since 1924, and even detecting a refinery explosion in Philadelphia and an asteroid entering Earth’s atmosphere south of Puerto Rico. Meanwhile, the program is focused on the redesign of the Advanced Baseline Imager radiator and the repair of the Geostationary Lightning Mapper to support the new GOES-T launch planning date of December 2021. The Ground Segment server replacement is also progressing, on plan to be completed before the GOES-T launch. GOES-U’s new space weather instrument, the Compact Coronagraph, passed its Critical Design review and is proceeding with fabrication.

July 08, 2019: NOAA/NASA Satellite Meteorology Summer Workshop

NOAA/NESDIS and the NASA Earth Sciences Division are holding a Satellite Meteorology Summer Workshop July 8-19 at the Cooperative Institute for Research in the Atmosphere (CIRA) in Fort Collins, Colorado. The workshop focuses on the theory and use of satellite data to engage graduate students and individuals with early postdoctoral appointments in the science of developing and using satellite data for the atmosphere, land, oceans and cryosphere. The program includes internationally recognized experts in radiative transfer theory, satellite meteorology, and numerical weather prediction at both the global scale and mesoscale. The objective of the workshop is to foster education of the next generation of satellite meteorologists and promote the use of observations from the latest operational and research satellite missions.

July 03, 2019: Parts of Chile and Argentina Experience Total Solar Eclipse

GOES East saw the moon’s shadow as it moved west to east across South America on July 2, 2019. Parts of Chile and Argentina experienced a total solar eclipse, which is when the moon passes between the sun and Earth, blocking out all of the light from the sun. Those in the path of totality were able to see the sun’s corona. While the eclipse began over the Pacific Ocean, La Serena, Chile, was one of the first cities in the path of totality to view the eclipse.

July 01, 2019: GOES-U Gets a New Instrument

GOES-U, scheduled to launch in late 2024, won’t be an exact replica of its siblings in the GOES-R Series. That’s because GOES-U will accommodate an additional space weather instrument, the Naval Research Laboratory’s Compact Coronagraph (CCOR). CCOR recently completed its Critical Design Review, which affirmed that the design meets requirements and is ready to proceed with full-scale fabrication, assembly, integration and test. CCOR will image the solar corona (the outer layer of the sun’s atmosphere) and help detect and characterize coronal mass ejections (CMEs).

June 21, 2019: GOES East and GOES West See Summer Solstic

On June 21, GOES East and GOES West simultaneously saw the slanted shadows separating day and night on Earth just minutes after the summer solstice occurred. Summer solstice is the start of astronomical summer in the Northern Hemisphere and the moment that hemisphere reaches its greatest tilt toward the sun. The solstice occurred at 11:54 a.m. EDT, when the sun's direct rays reached as far north as they could get, along the Tropic of Cancer, at 23.5 degrees North latitude. It was the longest day (and shortest night) of the year.

June 11, 2019: GOES-R Lightning Detection Fact Sheet

Rapid increases in total lightning (in-cloud and cloud-to-ground) activity often precede severe and tornadic thunderstorms. The GOES-R Series Geostationary Lightning Mapper (GLM) is the first operational lightning mapper flown in geostationary orbit. GLM data reveal convective storm development and evolution and provide insights beyond the presence of a lightning strike, including the spatial extent and distance lightning flashes travel. Trends in total lightning available from GLM provide critical information to forecasters, allowing them to identify initial thunderstorm development and focus on potentially severe storms before they produce damaging winds, hail or tornadoes. GLM can also aid with aviation route planning and early recognition of conditions conducive to lightning-ignited wildfires. The instrument has even been found useful in identifying meteors entering the Earth’s atmosphere.

June 7, 2019: GOES-16/17 Virtual Science Fair Winners Announced

The winners of the 2019 GOES-16/17 Virtual Science Fair were announced on June 7. Two middle school teams tied for first place: Auburn, Massachusetts, and Medford New Jersey. The high school first place team is from Santa Fe, New Mexico. Students from grades 6-14 were invited to participate in the virtual science fair. Each team used data from GOES-16 and GOES-17 to investigate weather and natural hazards. View all the science project submissions.

June 5, 2019: GOES-R Fire Detection and Characterization Fact Sheet

Fires, whether naturally occurring or manmade, have substantial impacts upon society. Wildfires can destroy vast tracts of land, releasing tons of aerosols and gases into the atmosphere, while destroying homes, wildlife habitats and valuable resources. Satellites allow for detecting and monitoring a range of fires, providing information about the location, duration, size, temperature, and power output of those fires that would otherwise be unavailable. With the GOES-R Series, this information can be used to track fires in real time, provide input data for air quality modeling, and help separate the impact of the fires from other sources of pollution. A new fact sheet highlights the new tools available for detecting and monitoring wildfires, observing and monitoring smoke from those fires, monitoring burn scars, and predicting flash flood events from rain events after a fire.

June 5, 2019: GOES-R Volcanic Ash Detection Fact Sheet

Volcanic ash is a significant health, aviation, infrastructure, and economic hazard. Volcanic emissions generate complex clouds that can affect local, regional, or, in the case of very large eruptions, global weather and climate. Given the remote location of most volcanoes and the rapid formation and expansion of volcanic clouds, geostationary satellites are the primary tool for identifying, tracking and characterizing volcanic clouds. GOES East and GOES West observe a significant fraction of the most volcanically active region on Earth, known as the “Pacific Ring of Fire.” The GOES-R Series provides a complete set of advanced volcanic cloud detection and monitoring products and tools. A new fact sheet highlights how forecasters use GOES-R volcanic ash applications to identify areas where ash is present and potentially hazardous and issue more accurate aviation, air quality, ground safety, and public health warnings.

June 4, 2019: Carbon Dioxide Levels in Atmosphere Hit Record High in May

Atmospheric carbon dioxide continued its rapid rise in 2019, with the average for May peaking at 414.7 parts per million (ppm) at NOAA’s Mauna Loa Atmospheric Baseline Observatory. The measurement is the highest seasonal peak recorded in 61 years of observations on top of Hawaii’s largest volcano and the seventh consecutive year of steep global increases in concentrations of carbon dioxide (CO2), according to data published on June 4, 2019, by NOAA and Scripps Institution of Oceanography. The 2019 peak value was 3.5 ppm higher than the 411.2 ppm peak in May 2018 and marks the second-highest annual jump on record.

June 3, 2019: Hurricane Research Gains Ground

With significant coastal populations and property at stake, two new studies by NOAA’s National Centers for Environmental Information (NCEI) and its research partners focus on the behavior of tropical cyclones. Because hurricanes can cause fatalities and billions of dollars in damage, the new research could contribute to greater preparedness, improved forecasts, and resiliency efforts. These studies delve into the speed, direction, and intensity of tropical cyclones.

June 3, 2019: GOES-R Snow and Ice Fact Sheet

The cryosphere includes snow, sea ice, lake and river ice, icebergs, glaciers, ice caps, ice sheets, ice shelves, permafrost, seasonally frozen ground, and solid precipitation. Changes in the cryosphere have major impacts on water supply, agriculture, transportation, freshwater ecosystems, hydropower production, health, and recreation. Notable cryosphere-related hazards include floods, droughts, avalanches, and sea-level rise. Satellite instruments are essential for delivering large-scale observations of the cryosphere and are a key to extending ground-based measurements. A new fact sheet highlights snow and ice applications from the GOES-R Series. Cryospheric observations and information from the GOES-R Series provide a new opportunity to continuously observe snow and ice from geostationary orbit, improving weather forecasting and hazard warnings and helping to reduce the risk of loss of life and property from natural and human-induced disasters. These observations provide a better understanding of environmental factors that affect human health and well-being, are critical to marine navigation at high latitudes, and improve the management of water resources, and terrestrial, coastal and marine ecosystems.

May 23, 2019: New Tools for Monitoring Hurricanes in a Changing Climate

Hurricanes are one of the most menacing natural hazards, especially for island and coastal populations. A warming climate is expected to impact sea level rise, storm surge, tropical cyclone rainfall rates, and tropical cyclone intensity. We are also seeing a pattern of slower storms, remaining stationary over a location for longer periods of time and increasing flooding impacts. This isn’t great news for the millions of people in the paths of hurricanes each year. Fortunately, we have two new advanced geostationary satellites, NOAA’s GOES-16 and GOES-17 that continuously view the entire Atlantic and Eastern/Central Pacific hurricane basins. The latest generation of GOES carry sophisticated instruments that provide new and dramatically improved capabilities for forecasting, tracking and monitoring hurricanes as well as the environmental conditions that cause them to form.

May 23, 2019: NOAA Predicts Near-Normal 2019 Atlantic Hurricane Season

The 2019 Atlantic hurricane season begins on June 1. The National Oceanic and Atmospheric Administration’s (NOAA‘s) Climate Prediction Center is forecasting a near-normal Atlantic hurricane season. For 2019, NOAA predicts a likely range of 9 to 15 named storms (winds of 39 mph or higher), of which 4 to 8 could become hurricanes (winds of 74 mph or higher), including 2 to 4 major hurricanes (category 3, 4 or 5; with winds of 111 mph or higher). This outlook reflects competing climate factors. The ongoing El Nino is expected to persist and suppress the intensity of the hurricane season. Countering El Nino is the expected combination of warmer-than-average sea-surface temperatures in the tropical Atlantic Ocean and Caribbean Sea, and an enhanced west African monsoon, both of which favor increased hurricane activity. In addition to the Atlantic hurricane season outlook, NOAA also issued the seasonal hurricane outlook for the central Pacific basin. The Central Pacific Hurricane Center announced a 70% chance of above-normal tropical cyclone activity during the central Pacific hurricane season this year and predicted 5 to 8 tropical cyclones for the central Pacific basin.

May 14, 2019: GOES-R Cloud and Moisture Imagery Fact Sheet

Cloud and moisture imagery is the satellite imagery that forecasters and the public are accustomed to viewing in weather forecast offices, on the web and in the news. Cloud and moisture imagery includes digital maps of observed land, water and clouds. A new GOES-R cloud and moisture imagery fact sheet explains what types of imagery the Advanced Baseline Imager (ABI) provides. The GOES-R Series ABI measures energy at different wavelengths, which is either reflected (visible and near infrared) or emitted (infrared) from the Earth’s surface. The ABI increases spatial resolution (to better monitor small-scale features), provides faster coverage (to improve temporal sampling and to scan additional regions) and adds spectral bands (to enable new and improved products for a wide range of phenomena). ABI provides advanced measurements of atmospheric and surface conditions such as sea and land surface temperatures, vegetation, clouds, aerosols, hurricanes, winds, water vapor, rainfall, snow and ice cover, fire locations, smoke plumes, volcanic ash and gas, atmospheric temperature and moisture, and ozone.

May 14, 2019: GOES-R Aerosols/Air Quality Fact Sheet

Aerosols are solid and semi-solid particles suspended in the air that have harmful impacts on human health and the environment. GOES-R Series satellites provide a host of aerosol imagery and quantitative retrieval products for air quality monitoring and forecasting applications. A new GOES-R aerosols/air quality applications fact sheet explains how GOES-R satellites enable forecasters to better monitor areas of smoke and dust, which can be critical factors in visibility, aviation and air quality forecasts. In addition to short-term prediction, they also enable better monitoring of the long-term trends in aerosol quantities and distribution throughout the atmosphere to help climate scientists monitor and predict climate change.

May 5, 2019: Hurricane Preparedness Week

April 29, 2019: NOAA and Air Force Reserve ‘Hurricane Hunters’ to visit East Coast on preparedness tour

In an effort to build a Weather-Ready Nation ahead of this year’s Atlantic hurricane season, NOAA hurricane experts will tour five eastern U.S. cities from May 6-10 to raise awareness of the importance of preparing for the upcoming hurricane season. At each stop, the public and media can take a tour of the “hurricane hunter” aircraft that fly around and directly into the eye of a storm — a NOAA WP-3D Orion aircraft and a U.S. Air Force Reserve WC-130J aircraft.

April 22, 2019: Celebrate Earth Day with these Geostationary Satellite Images

Earth Day was born from former Wisconsin Sen. Gaylord Nelson’s desire to bring environmental issues to the forefront of the national political agenda. The first Earth Day, held on April 22, 1970, was followed by the creation of the U.S. Environmental Protection Agency (EPA) as well as the passage of the Clean Air, Clean Water and Endangered Species Acts. Today, more than 1 billion people will participate in Earth Day activities, raising awareness about critical environmental issues. In celebration of Earth Day, we’re taking a look at just how far satellite imagery has come since 1970.

April 19, 2019: How Satellites Play a Pivotal Role in Monitoring the Health of Coral Reefs

Coral reefs are one of the most productive and biodiverse ecosystems in the world. They cover an estimated 110,000 square miles of the ocean floor and are home to more than 25 percent of marine species for at least some part of their lives. As part of this year’s Earth Day theme, “Protect Our Species,” we’re looking at how NOAA’s satellites are monitoring the effects of climate change on coral reefs around the globe. Using a combination of NOAA and international partners’ satellites, Coral Reef Watch can monitor ocean temperatures and identify areas at risk for coral bleaching. The Advanced Baseline Imager (ABI) aboard the GOES-R satellite series and NOAA-20’s Visible Infrared Imaging Radiometer Suite (VIIRS) provide data on ocean temperatures by looking at the infrared radiation that’s emitted from the ocean.

April 19, 2019: Hurricane Michael Upgraded to a Category 5 at Time of U.S. Landfall

Scientists at NOAA’s National Hurricane Center conducted a detailed post-storm analysis on all the data available for Hurricane Michael and have determined that the storm’s estimated intensity at landfall was 160 mph. This makes Michael a category 5 storm on the Saffir-Simpson Hurricane Wind Scale at the time of landfall on October 10, 2018, near Mexico Beach and Tyndall Air Force Base, Florida. Michael was the first hurricane to make landfall in the United States as a Category 5 since Hurricane Andrew in 1992, and only the fourth on record.

April 16, 2019: New Tools for Monitoring Volcanic Ash

Volcanic ash is a significant health, aviation, infrastructure and economic hazard. GOES East and GOES West observe a significant fraction of the most volcanically active region on Earth, known as the “Pacific Ring of Fire.” New capabilities from the GOES-16 and GOES-17 Advanced Baseline Imager and Geostationary Lightning Mapper provide improved volcanic hazard forecasting and monitoring through sophisticated new data products and automated detection tools. As forecasters gain more experience with new GOES-R Series datasets, the value of the measurements will increase significantly, resulting in safer and more efficient air transportation and a better understanding of volcanic processes and the complex relationship between volcanic emissions and weather and climate.

April 8, 2019: 1st Quarter 2019 GOES-R Program Newsletter

The GOES-R Series Program quarterly newsletter for January – March 2019 is now available. GOES-17 is now operational as GOES West and we now have advanced geostationary satellite capabilities for more than half the globe. The program remains as busy as ever, with the team continuing to work on GOES-16 and 17 data product validation, the ground system server refresh, the GOES-T/U Advanced Baseline Imager cooling system redesign, and the build of our next two satellites in order to ensure continuity of GOES-R series operations for many years to come.

April 3, 2019: GOES-16 Monitors Record Flooding in the Midwest

The National Weather Service (NWS) is reporting an accelerated flood season across the Midwestern United States. On March 13, 2019, a winter storm system intensified and swept across much of the Central U.S., causing heavy rain, severe thunderstorms, snow, and blizzard conditions. The storm led to widespread flooding across parts of South Dakota, Nebraska and Iowa. New flood products, utilizing GOES-R Series and JPSS data, are helping forecasters better determine where and when flooding will occur and aiding officials in determining where to deploy resources during a flood event.

April 2, 2019: Case Study: Saving GOES-17

Aerospace America published an article “Saving GOES-17,” authored by John Van Naarden, Advanced Baseline Imager chief engineer at Harris Corp., and Dan Lindsey, NOAA’s senior scientific advisor to the GOES-R Program. The article outlined the issues that were discovered with the cooling system on GOES-17’s primary instrument, the Advanced Baseline Imager, and efforts to improve performance of the instrument. Despite a thermal system operating at only about 5% of its capacity, ABI is now delivering more than 97% of its intended data, thanks to recovery efforts.

April 2, 2019: New ABI Scan Mode

On April 2, 2019, the GOES-16 and GOES-17 Advanced Baseline Imagers began operating in a new scan mode, 10-minute flex mode. Ten-minute flex mode is very similar to the previous default flex mode with one exception: a full disk image is generated every 10 minutes instead of every 15 minutes. Contiguous U.S. (CONUS) for GOES-16/ Pacific U.S. (PACUS) for GOES-17 scans (3000 km by 50000 km) are still provided every five minutes, in addition to two mesoscale domains (1000 km by 1000 km) every 60 seconds (or one domain every 30 seconds if scanning the same domain). The new scan mode allows NOAA to match the full-disk scanning cadence of our international partners and will be critical to National Weather Service Weather Forecast Offices, National Centers, and the Volcanic Ash Advisory Centers in monitoring hazardous weather conditions and providing additional information in observationally limited areas.

March 20, 2019: NOAA’s Spring 2019 Flood and Climate Outlook

According to NOAA's spring flood and climate outlook, a wet winter has primed much of the Great Plains for spring flooding in 2019, with major flooding likely along the Red River of the North, the Missouri, and the Mississippi Rivers. Moderate flood risk extends upstream of those rivers to their tributaries, including the lower Ohio, the Cumberland, and Tennessee Rivers. Minor flood risk covers nearly the entire country east of the Mississippi as well as parts of Washington, Oregon, and California.

March 19, 2019: GOES-16 and GOES-17 Used in Drought Monitoring and Prediction

Researchers are using satellite data to alert farmers and ranchers about impending flash droughts. Thermal infrared imagery from both the GOES-R Series satellites, as well as polar orbiting satellites like NOAA-20 and Suomi-NPP, is used to estimate evapotranspiration, which is a measure of how much water is being transferred from the land to the atmosphere through the soil and plants. Using a tool called the Evaporative Stress Index (ESI), it’s now possible to deliver a probabilistic forecast, like the ones we get from the National Weather Service, a month or so ahead of the onset of a flash drought. New tools and better forecasts give the agricultural sector even more options to deal with drought and can help mitigate their future impact.

March 08, 2019: 2018 NOAA Science Report

The 2018 NOAA Science Report is now available. The report highlights NOAA’s research accomplishments and the vital service’s the agency provides to Americans every day. The science report spans the entire range of NOAA’s mission, and the 72 stories featured in this year’s report represent a selection of NOAA’s research and development accomplishments. The GOES-R mission is highlighted in several areas of the report, including the GOES-S (17) launch, lightning detection, solar imaging and space weather monitoring, fire detection and monitoring, flood mapping, and hurricane tracking.

March 5, 2019: NOAA Talks Hurricanes and Climate at National Press Club

Each year, NOAA helps the United States prepare for hurricanes by issuing a seasonal outlook before the official start of the season on June 1. Gerry Bell, Ph.D., from NOAA’s Climate Prediction Center, spoke to reporters at the National Press Club on March 5 about how NOAA creates this outlook and the climate drivers that fuel or suppress a hurricane season. Bell said the Atlantic remains in a period of increased hurricane activity that began in 1995 and generates more, stronger, and longer-lived storms. Bell also identified several global climate patterns that can drive hurricane development within that high-activity era. The Atlantic Multi-decadal Oscillation (AMO) influences hurricane seasons over several decades and the El Nino/Southern Oscillation (ENSO) drives year-to-year variability. “By predicting key climate patterns, we can often predict these regional hurricane-controlling conditions, and therefore predict the strength of the upcoming hurricane season,” he said.

March 4, 2019: A Long View of California’s Climate: Study Examines Centuries of Data to Understand Climate-Wildfire Links

Deadly severe wildfires in California have scientists scrutinizing the underlying factors that could influence future extreme events. Using climate simulations and paleoclimate data dating back to the 16th century, a recent study looks closely at long-term upper-level wind and related moisture patterns to find clues. New research published by the Proceedings of the National Academy of Sciences USA examines jet stream and moisture patterns in California over a centuries-long time period—1571 to 2013. The work provides a stronger foundation and a longer-term perspective for evaluating regional natural hazards within California and the economic risks to one of the world's largest economies.

February 20, 2019: Keeping an Eye on Rivers in the Sky

Atmospheric rivers are long, narrow conveyor belts of moisture that move through the atmosphere. Strong atmospheric rivers can deliver enormous amounts of rain and high-elevation snow in California, Pacific Northwest, and Alaska, especially during the winter months. The GOES-R Series Advanced Baseline Imager provides improved detection and monitoring of atmospheric river events. Understanding and anticipating the role of atmospheric rivers is important for water and emergency management on the West Coast, particularly in California. GOES-17, recently designated NOAA’s GOES West operational satellite, is positioned to keep an eye on the western U.S., Alaska and Pacific Ocean, and provide advanced monitoring of atmospheric rivers among other weather phenomena and hazards.

February 14, 2019: NOAA Satellites Helped Rescue 340 People in 2018

In 2018, the NOAA Search and Rescue Satellite Aided Tracking (SARSAT) system helped save 340 lives with the aid of NOAA satellites like GOES-16. In addition to carrying instruments for monitoring our atmosphere, land and oceans for severe weather and other hazards, GOES-16 also carries a SARSAT transponder to help locate people in distress. This transponder provides the capability to immediately detect distress signals from emergency beacons and relay them to ground stations. In turn, this signal is routed to a SARSAT mission control center and then sent to a rescue coordination center, which dispatches a search and rescue team to the location of the distress.

February 12, 2019: GOES-17 is Now Operational as NOAA’s GOES West!

GOES-17 is now operational as NOAA’s GOES West. In its new role, GOES-17 is providing faster, more accurate, and more detailed observations for detecting and monitoring Pacific storm systems, fog, wildfires, and other weather phenomena that affect the western United States, Alaska, and Hawaii. Located at 137.2 degrees west longitude, GOES-17 replaces GOES-15 as NOAA’s operational GOES West. GOES-17 joins GOES-16, in operations as NOAA’s GOES East, in delivering high-resolution visible and infrared imagery and lightning observations of more than half the globe – from the west coast of Africa to New Zealand and from near the Arctic Circle to the Antarctic Circle. View GOES-17 operational imagery.

February 6, 2019: Assessing the Global Climate in 2018

For the globe, 2018 became the fourth warmest year on record and the United States experienced 14 billion-dollar weather and climate disasters. These are findings from the 2018 Annual Global Climate Report from NOAA National Centers for Environmental Information, which is part of the suite of climate services NOAA provides to government, business, academia and the public to support informed decision-making. Earth’s long-term warming trend continued in 2018 as persistent warmth across large swaths of land and ocean resulted in the globe’s fourth hottest year in NOAA’s 139-year climate record. The year ranks just behind 2016 (warmest), 2015 (second warmest) and 2017 (third warmest). In separate analyses of global temperatures, scientists from NASA, the United Kingdom Met Office and the World Meteorological Organization also reached the same heat ranking.

February 5, 2019: GOES East Sees Partial Solar Eclipse

GOES East captured a partial solar eclipse on February 5, 2019. In this animation from the satellite’s Solar Ultraviolet Imager (SUVI) instrument, you can see the moon passing across the sun. A partial eclipse occurs when the sun and moon are not exactly in line with the Earth and the moon only partially obscures the sun.

February 5, 2019: GOES-16 Detects Meteor over Cuba

On February 1, 2019, at 1:17 p.m. EST, the GOES-16 Geostationary Lightning Mapper (GLM) detected a bright meteor over northwestern Cuba. The meteorite landed near Viñales, Pinar del Río in western Cuba. While designed for mapping lightning flashes, GLM can observe large meteors anywhere throughout its coverage area. The instrument takes 500 images of Earth every second, allowing it to measure the shape of a meteor “light curve,” or the change in brightness of a meteor with time, with millisecond precision.

The GOES-16 Advanced Baseline Imager also detected the airborne debris cloud as it drifted northeastward then eastward for about an hour after the impact. The signatures in the split cloud top phase and split window imagery were due to the presence of mineral dust particles within the debris cloud — the emissivity properties of dust affects the sensed brightness temperatures differently for various infrared spectral bands. The cirrus spectral band is useful for detecting the scattering of light by airborne particles such as ice crystals, volcanic ash, smoke or dust. The debris cloud was also casting a subtle shadow onto the surface, as seen in the visible imagery.

January 31, 2019: The latest GOES-R Series Quarterly Newsletter is now available for download
