LATEST VIDEO: Earth from Orbit: Summer Solstice

Earth from Orbit: GOES-18 GOES West

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.

Earth from Orbit: GOES-18 GOES West

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.

Earth from Orbit: 2022 Hurricane Season Begins

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. Download Video | Transcript Credit: NOAA/NASA Goddard Space Flight Center/CIRA

Earth from Orbit: Flashy First Imagery from the GOES-18 Geostationary Lightning Mapper

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.

Earth from Orbit: Wildfires Across the Plains and Southwest

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. Download Video | Transcript Credit: NOAA, NASA Goddard Space Flight Center, CIRA

Earth from Orbit: Earth Day 2022

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.

Earth from Orbit: Spring Snowstorm Hits U.S.:

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.

Earth from Orbit: Vernal Equinox:

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.

Earth from Orbit: Catching Bolides:

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.

Kona Low Slams Hawaii:

NOAA satellites monitored a large “kona low” storm system that brought drenching rain, flash flooding, and blizzard conditions to Hawaii. The system moved directly over the islands on Dec. 4, 2021, prompting Hawaii’s governor to declare a state of emergency. A kona low, or kona storm, is a seasonal subtropical cyclone that occurs in Hawaii during the winter months Download Video | Transcript Credit: NOAA/NASA Goddard Spaceflight Center/CIRA/CIMSS

2021 Hurricane Season Comes to a Close:

The 2021 Atlantic Hurricane Season officially came to a close on Nov. 30 and was the third-busiest Atlantic season on record. This year, a total of 21 named storms formed, seven of which became hurricanes. Of these, four were considered major (Category 3 or above) on the Saffir-Simpson Hurricane Wind Scale. NOAA satellites monitored and tracked all of the storms, providing vital data to safeguard communities. Download Video | Transcript Credit: NOAA/NASA Goddard Space Flight Center/CIRA

Earth from Orbit: 5 Haunting Sights from NOAA Satellites:

NOAA satellites have a boo-tiful view of Earth, 24/7. Sometimes they see some haunting sights, like moon glint or the moon creeping near the edge of Earth. When monitoring hurricanes, GOES satellites have captured eerie imagery that looks skulls in these monster storms. Graveyards are home to ghosts and ghouls, not satellites. But when a GOES satellite reaches its end of life, it’s sent to what’s called a graveyard orbit, out of the way of busier operational orbits. Finally, we ain’t afraid of no GOES-Ts. We’re excited for the upcoming launch of the latest sequel in the GOES-R Series. Happy Halloween from NOAA Satellites!

Earth from Orbit: Atmospheric River Hits the West Coast:

On October 25, 2021, a phenomenon called an “atmospheric river” dumped heavy rain and mountain snow across the Western U.S. and Canada. Atmospheric rivers are long, narrow belts of moisture that move through the atmosphere. They can deliver large amounts of rain, and high-elevation snow. This deluge of rain can help end droughts but also can produce flash flooding and mudslides in some areas. NOAA satellites monitor these rivers in the sky as they make their way over the West Coast.

Hurricane Sam Powers Across the Atlantic:

As Hurricane Sam churns in the Atlantic Ocean, NOAA satellites are carefully monitoring the powerful Category 4 storm, the strongest of the 2021 Atlantic hurricane season to date. Sam formed on Sept. 23 and rapidly intensified into a Category 4 hurricane by Sept. 25. Sam’s rate of intensification was the highest on record that far east in the Atlantic this late in the calendar year. Satellite observations showed convective bursts and the presence of a defined, stable eye during rapid intensification. Significant lightning activity was also seen within the eyewall as Sam rapidly intensified. Despite several fluctuations in intensity, Sam has maintained major hurricane strength since Sept. 25.

Atlantic Hurricane Season Hits Its Peak:

September 10 marked the peak of the Atlantic hurricane season. Climatologists determined this peak date by recording the total number of named storms in the Atlantic basin over the last 100 hurricane seasons and taking an average of when the most storms occur. Around 75% of Atlantic seasons since the beginning of the satellite era in 1966 have had at least one named storm on September 10 and about 50% of seasons have had at least one active hurricane on that date. Tropical activity tends to peak around this time because of warmer Atlantic Ocean temperatures and weaker wind shear. NOAA satellites recently monitored several storms in the Atlantic during hurricane season’s peak. Download Video | Transcript NOAA/NASA Goddard Space Flight Center/CIRA

Earth from Orbit: Hurricane Ida Causes Days of Destruction:

Hurricane Ida caused intense flooding and destruction from the Gulf of Mexico to New England, and is blamed for several fatalities. Ida struck Louisiana near Port Fourchon on August 29 as a powerful Category 4 storm, with maximum sustained winds of 150 miles per hour. The storm made landfall in Louisiana on the 16th anniversary of Hurricane Katrina, and is tied with 2020’s Hurricane Laura and the Last Island Hurricane in 1856 for the strongest maximum sustained winds at landfall for a Louisiana hurricane. In just three days, Ida rapidly progressed from a tropical wave to a hurricane. After striking Cuba’s Isle of Youth as a Category 1 hurricane on August 27, Ida headed northward and rapidly intensified to a Category 4 hurricane. Ida moved inland and brought heavy rainfall and widespread flooding from the Tennessee and Ohio Valleys into the Central and Southern Appalachians and mid-Atlantic, bringing record rainfall and deadly flooding to the New York region. NOAA satellites monitored the progression of the storm as it developed and intensified. Download Video | Transcript Credit: NOAA/NASA Goddard Space Flight Center/CIRA/CIMSS

Earth from Orbit: Hurricane Season Heats Up:

As we approach the peak of Atlantic hurricane season, activity in the tropics is ramping up. NOAA satellites are monitoring storms in both the Atlantic and Pacific Oceans. Tropical Storm Fred formed on Aug. 11, 2021 and made landfall on the eastern Florida panhandle on Aug. 16. Tropical Storm Grace developed on Aug. 14 in the Caribbean Sea and strengthened into a hurricane on Aug. 18 as it approached Mexico’s Yucatan Peninsula. And Tropical Storm Henri developed south of Bermuda on Aug. 16. Meanwhile, hurricane Linda churns in the eastern Pacific. As hurricane season heats up, NOAA satellites provide critical data for forecasting and tracking the location, movement and intensity of the storms.

Earth from Orbit: Fires Rage Across the Globe:

As wildfires continue to rage in North America, and the Dixie Fire became the second largest in California history, fire activity has also spiked across the globe. Thick smoke from the hundreds of wildfires burning in Siberia has reached parts of Mongolia, western Greenland, and, for the first time in recorded history — the North Pole. Hundreds of fires are also raging in Greece, Italy, Algeria and Turkey among one of the worst heat waves in decades. NOAA’s satellites and those from our partners across the globe are providing critical data for detecting and tracking the hundreds of fires that are burning worldwide as well as monitoring reduced visibility and air quality from the smoke produced by the blazes. These observations aid forecasters, decision-makers, and first responders. Download Video | Transcript Credit: NOAA/NASA Goddard Space Flight Center/CIRA/EUMETSAT

Earth from Orbit: Wildfires Spawn Severe Weather:

Wildfires continue to rage in the western U.S. Some of the fires are so intense, they’re creating their own severe weather. NOAA satellites are monitoring wildfire conditions as well as fire-generated storms. Intense heating by wildfires can generate a smoke-infused thunderstorm or pyrocumulonimbus cloud. These clouds can produce lightning and generate strong winds, making it more difficult to contain the spread of fire. In rare instances, they can even spawn a tornado. The Bootleg Fire in Oregon produced a tornado on July 18, 2021. When wildfires spawn severe weather, dangerous conditions become even worse. NOAA satellites are our eyes in the sky, detecting and monitoring wildfires as well as storms created by the most intense fires.

Earth from Orbit: Satellites and Solar Energy:

Sunglint from solar panels is often observed in satellite imagery. While an interesting phenomenon to see, there’s actually an important connection between satellite observations and solar energy production. Detailed data about clouds from NOAA satellites can aid solar energy forecasts. Clouds affect the output of solar power generation systems. GOES-16 (GOES East) and GOES-17 (GOES West) monitor what types of clouds are present, how they are distributed in the sky, how much shadow they are creating over solar farms, and where they will move next. This provides valuable information about the variations that can occur in power production over the next few minutes to hours. As demand for solar energy grows, the need for timely, detailed information about solar radiation and cloud cover is essential. GOES-16 and GOES-17 provide critical data for harnessing solar energy and efficiently delivering it to consumers. Download Video | Transcript Credit: NOAA/NASA Goddard Space Flight Center/CIRA

Earth from Orbit: Wildfire Smoke Blankets U.S.:

Wildfire activity amid extreme heat and drought has resulted in smoke blanketing much of the United States and Canada. NOAA satellites are monitoring the fires and their smoke output as well as the effects of the smoke on air quality, visibility, and weather. The satellite data are critical for forecasters, decision-makers, and first responders. Download Video | Transcript Credit: NOAA/NASA Goddard Space Flight Center/CIRA

Earth From Orbit: Record Heat and Drought Raising Risk of Wildfire:

The western U.S. has seen record-breaking high temperatures over the past week as a heat dome, or mass of warm air, blankets the Pacific Northwest. This essentially occurs when a “mountain” or “dome” of warm air rises into the atmosphere, gets pinched off by the jet stream, and blocks new weather systems from moving in. The extreme heat, coupled with a severe drought this spring and summer in the region, has combined to significantly raise the risk of wildfire from both human and natural hazards, such as lightning. As the drought and heat wave stretches on, vegetation in these areas dries out, creating ample fuel for potential wildfires. But how dry is it? Learn how NOAA satellites help monitor fires and fire weather conditions that can lead to increased likelihood of them occurring.

Earth From Orbit: Tropical Storm Claudette Batters Southeastern U.S.:

This past weekend, NOAA satellites closely monitored Tropical Storm Claudette, the third named storm of the 2021 Atlantic hurricane season. Claudette slammed into the Gulf and southeastern coasts of the U.S., causing severe damage in parts of the Deep South. The storm was officially named on June 19 after it organized and strengthened near the town of Houma in southeastern Louisiana. It is the fifth-earliest third-named storm to form in the Atlantic basin since 1950. Download Video | Transcript Credit: NOAA/NASA Goddard Space Flight Center/CIRA

Earth from Orbit: Fire Season Heats Up:

Fire weather is heating up across the western United States, exacerbated by an intense heatwave and ongoing severe drought. NOAA satellites are monitoring numerous wildfires and keeping watch on areas primed for ignition. As of June 17, 2021, 33 large fires are currently active, burning more than 400,000 acres in 10 states. NOAA satellites zoomed in on several of the major fires burning in the western U.S, including the Telegraph and Mescal Fires in southeastern Arizona, Pack Creek and Bear Fires in Utah, and the Robertson Draw Fire in Montana. Data from the satellites help forecasters monitor drought conditions, locate hot spots, detect changes in a fire’s behavior, predict a fire’s motion, and monitor smoke and air quality Download Video | Transcript Credit: NOAA/NASA Goddard Space Flight Center/CIRA

Earth from Orbit: Actinoform Clouds:

NOAA satellites captured actinoform clouds over the eastern Pacific Ocean on June 3, 2021. These collections of shallow clouds, organized in a distinctive radial pattern, often appear as leaf-like or reminiscent of wagon wheel spokes. They are commonly observed over open water in the Pacific Ocean, in areas where stratocumulus clouds form. These cloud formations are usually so large that they cannot be seen from below. They were first observed in 1962, by NASA’s TIROS V satellite. It’s not yet clearly understood how these complex clouds organize, and studying these clouds with NOAA’s advanced satellite sensors may lead to important new insights about our atmosphere.

Earth from Orbit: Supercells Strike Louisiana and Texas:

Severe storms struck Louisiana and Texas on May 17, 2021, producing heavy rain, extensive flooding, damaging winds, large hail, and several tornadoes. Hail the size of baseballs was reported near Girard, Texas, and wind gusts of more than 70 mph downed trees and damaged buildings. The storms produced several tornadoes. Torrential rain fell over parts of eastern Texas and Louisiana, producing widespread flooding. At least four people died amid floodwaters after more than a foot of rain fell in Lake Charles and 10 inches in Baton Rouge. GOES-16’s orbit allows the satellite to keep vigilant watch over a fixed area and capture storms in motion. The ability to monitor clouds and atmospheric conditions in near-real time helps forecasters track rapidly changing weather conditions and give advance warning of severe thunderstorms, tornadoes, and flooding.

This Week in Weather: Gravity Waves:

On April 3, 2021, NOAA’s GOES-16 and NOAA-20 satellites viewed gravity waves rippling over Western Pennsylvania. Waves form in the atmosphere when air is disturbed, like a stone dropped into a calm pond. The gravity waves seen over Pennsylvania were caused by air being forced upward by hills into a layer of stable air. Gravity causes the air to fall back down, and it begins to oscillate, creating a ripple effect. Download Video | Transcript Credit: NOAA/NASA/CIRA

This Week in Weather: Severe Storms Strike Southern U.S.:

From March 17-18, 2021, a severe weather outbreak swept across the Southern U.S. The storms produced damaging winds, large hail, and dozens of tornadoes, including significant EF2 tornadoes in Mississippi and Alabama. Throughout the event, GOES-16 (GOES East) monitored conditions and tracked the storms in real time. The satellite provided important information on cloud properties, storm structure, and lightning activity within the storms.

This Week in Weather: Late-Season Snowstorm Breaks Records:

A late-season snowstorm dropped feet of snow in parts of Colorado, Wyoming, Nebraska and South Dakota from March 13-14, 2021. Record-breaking snowfall was measured in Cheyenne, Wyoming and Denver, Colorado. NOAA’s geostationary satellites, GOES-16 (GOES East) and GOES-17 (GOES West) and polar-orbiting NOAA-20 and Suomi-NPP satellites monitored a low-pressure system in the region and followed its evolution into an historic storm. The satellites allowed scientists to forecast the storm’s path and intensity while providing early warning. They also kept watch throughout the event, monitoring the progression of the storm and resulting snow cover. Download Video | Transcript Credit: NOAA/NASA Goddard Space Flight Center/CIRA

Tracking Fires from Space:

From March 7-9, 2021, NOAA satellites monitored numerous fires over the Southern Plains. GOES-16 (GOES East) observed these fires in near-real time. By keeping constant watch over the same area, GOES-16 helps to locate fires, detect changes in a fire’s behavior, and predict its motion. The NOAA-20 satellite captured high-resolution imagery of the fires on March 9. This satellite’s VIIRS instrument has an imager band with high spatial resolution, at 375 meters per pixel, which allows it to detect smaller, lower temperature fires. Together, the satellites monitored both the hot spots and smoke plumes from the fires. 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.

Superior Flow of Clouds:

On March 1, 2021, NOAA satellites monitored lake-effect clouds flowing over Lake Superior. The satellites captured light snow bands embedded in the clouds. Lake-effect snow occurs when very cold air moves over the warmer waters of a lake. GOES-16 viewed the clouds in motion and tracked convection within them, while NOAA-20 captured the scene in stunning detail when the satellite passed over that afternoon. Specialized GOES-16 imagery distinguished snow/ice (white) from the clouds (yellow). Download Video | Transcript Credit: NOAA/NASA/CIRA

This Week in Weather: Tracking Dust in the Wind:

From Feb. 17–22, 2021, NOAA satellites monitored a large plume of dust from the Sahara Desert as it traveled off the west coast of North Africa and across the Atlantic Ocean. The Saharan Air Layer (SAL), a mass of dry, dusty air that forms over the Sahara Desert, can transport dust far away from the Sahara throughout the year. NOAA satellites like the geostationary GOES-16 and GOES-17 and the polar-orbiting NOAA-20 and NOAA/NASA Suomi-NPP help forecasters and scientists to continuously monitor the evolution of SAL outbreaks and their effects on the meteorology and climatology of the tropical North Atlantic.
