    Winter is just around the corner.
    Winter is just around the corner.

    As we move into the colder and snowy months of the year, NOAA’s next generation of geostationary and polar-orbiting satellites will be a critical source for monitoring and forecasting whatever weather winter throws our way. GOES-16 and GOES-17 bring state-of-the-art observational capabilities, with the 16-band Advanced Baseline Imager (ABI) and the first-of-its-kind Geostationary Lightning Mapper (GLM). These sensors give scientists and forecasters better and faster weather data during the United States’ often-turbulent winter months.

    Beyond the strike: Benefits of detecting lightning from space

    The GOES-R Series Geostationary Lightning Mapper (GLM) is the first instrument of its kind in geostationary orbit. It detects total lightning (in-cloud and cloud-to-ground) activity and reveals the spatial extent and distance lightning flashes travel. Rapid increases in total lightning activity often precede severe and tornadic thunderstorms and can be an indication that a hurricane is strengthening. GLM data is critical for a number of public safety applications as well as for predicting changes in climate.

  • October 17, 2019: NOAA Issues 2019-2020 Winter Outlook

    NOAA’s 2019-20 Winter Outlook map for temperature shows warmer-than-average temperatures are likely for much of the U.S. this winter.
    NOAA’s 2019-20 Winter Outlook map for temperature shows warmer-than-average temperatures are likely for much of the U.S. this winter.

    Warmer-than-average temperatures are forecast for much of the U.S. this winter according to NOAA’s Climate Prediction Center. Although below-average temperatures are not favored, cold weather is anticipated and some areas could still experience a colder-than-average winter. Wetter-than-average weather is most likely across the northern tier of the U.S. during winter, which extends from December through February. NOAA’s seasonal outlooks provide the likelihood that temperatures and total precipitation amounts will be above-, near- or below-average, and how drought conditions are favored to change. The outlook does not project seasonal snowfall accumulations as snow forecasts are generally not predictable more than a week in advance. Even during a warmer-than-average winter, periods of cold temperatures and snowfall are expected. Seasonal outlooks help communities prepare for what is likely to come in the months ahead and minimize weather's impacts on lives and livelihoods.

  • October 16, 2019: Satellite Imagery RGBs: Adding Value, Saving Time

    This GOES-17 (GOES West) air mass RGB imagery shows a hurricane-force low (the remnants of Super Typhoon Hagibis) over the Bering Sea and a storm-force low over the Gulf of Alaska.

    With the advent of the GOES-R Series, forecasters now have an overwhelming amount of information to sift through. The Advanced Baseline Imager (ABI) instrument has 16 channels that image Earth’s weather, oceans and environment as often as every 30 seconds. How can meteorologists quickly discern the information they need to issue timely forecasts and warnings? Scientists are working on new ways to combine information from multiple ABI channels to enhance meteorological features of interest. The result is a variety of red-green-blue or “RGB” composite imagery. The stunning, colorful imagery you see from GOES-16 and GOES-17 isn’t just beautiful to look at, it also provides critical information to forecasters for situational awareness and nowcasting rapidly changing weather.

    Lightning in the eye and rainbands of Hurricane Dorian on September 1, 2019, captured by GOES-16 (GOES East).

    During a hurricane, instruments on NOAA-20 and S-NPP capture data twice a day. These data are converted into brightly colored pictures that reveal the structure, intensity and temperature of a storm, along with other features, such as lightning and gravity waves. GOES East and West satellites also show the storm’s evolution by measuring infrared and visible radiation from the atmosphere and surface in real-time. These measurements tell us about wind at various levels in the atmosphere, sea surface temperatures and cloud properties. During major storms, it’s common for these images to circulate on social media and surface in news articles and on television reports. But without the trained eye of a meteorologist, it can be a challenge for most people to know what to make of them. Using a series of images from Hurricane Dorian, NOAA created a guide to understanding satellite images of hurricanes.

    A passenger aircraft undergoes maintenance in preparation for flight.

    If you were one of the more than 2.5 million people who flew safely through a U.S. airport today, you might want to thank your flight crew and a specialized team of meteorologists working behind the scenes. Aviation weather forecasting is important business: At any given time there are 5,000 aircraft crossing the skies over the U.S. According to the Federal Aviation Administration (FAA), inclement weather is by far the leading cause of flight delays, and delays cost airlines and passengers billions of dollars each year. NOAA aviation meteorologists work alongside FAA colleagues to ensure that any rapid changes in weather are quickly communicated to pilots in the sky. GOES data is an important part of those forecasts.

    Every day in America, millions of people wake up with the same question on their minds, “What’s the weather today?” The US Department of Commerce found that the majority of Americans check the weather forecast 3.8 times per day, equating to 301 billion forecasts consumed per year! These days, we take accurate forecasts — available multiple days in advance — for granted. This information wasn’t always as readily available as it is today. It takes a lot of smart science, technological infrastructure, and computing power to get the right data and information to generate a forecast. And the value of that information is profound. It helps people answer a wide variety of questions, from “What will I wear today?” to “When should I harvest my crops,” “When should I ship my product” or “When should I evacuate to avoid the storm?

    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).

    GOES-16 GLM and ABI composite of lightning illuminating a mesoscale convective system over Uruguay.

    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.

    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.

    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.

    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.

    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.

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

    16 images of the contiguous United States showing each of the ABI spectral bands. Visible imagery is shown in black and white and infrared imagery is colorized according to the features seen in each panel.
    The 16 spectral bands of the ABI are shown as a 16-panel panel image of the contiguous United States on December 22, 2017 from GOES-16. The first two bands sense in the visible, the following four in the near infrared, and the final ten in the infrared.

    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.

    Smoke plume from fire near Yosemite National Park, seen from ~25,000 feet on August 5, 2018. The smoke caused such poor air quality that emergency managers were forced to evacuate and close areas of the park.

    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.

    Coral bleaching process explained.

    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.

    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.

    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.

    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.

    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.

    NOAA’s 2019 Spring Flood Outlook map depicts the locations where there is a greater than 50% change of major, moderate or minor flooding March through May 2019.

    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.

    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.

    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.

This graphic represents a winter-average path of entry to California that could produce a very-wet, low-fire season in the state. Courtesy of NOAA NCEI.

    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.

    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.

    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-16 Detects Meteor over Cuba

    Meteor over Cuba captured by the GOES-16 GLM instrument.

    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.
