NOAA’s Latest GOES Weather Satellite Ready To Launch Next Week!", "description": "Join a NOAA expert on June 25, 2024 to celebrate the launch of the next and final installment of the GOES weather satellite series!From Earth weather to space weather, NOAA’s fleet of geostationary satellites play an important role in our everyday lives. And on June 25th, the fourth and final installation of the GOES-R series is set to launch from NASA’s Kennedy Space Center. As the final satellite in NOAA’s GOES-R (Geostationary Operational Environmental Satellites) series, GOES-U will continue to provide fast, clear and reliable weather-tracking information. GOES-U will provide real-time data for monitoring severe weather, hurricanes, wildfires, floods, fog and even lightning. Not only that, GOES-U carries a suite of instruments, including the first operational compact coronagraph, to monitor the Sun and warn us of approaching space weather hazards. A coronagraph is an instrument that blocks out the bright disk of the Sun so that researchers can see our star’s fainter outer atmosphere where much of the solar activity originates. This new coronagraph will better detect and characterize coronal mass ejections. The GOES series of weather satellites are parked in a geostationary orbit at points over the equator and rotate at the same speed as the Earth. The fixed location provides continuous coverage of weather conditions across the Western hemisphere. Once in orbit GOES-U will be renamed GOES-19. After an on-orbit check out to ensure its instruments and systems are working properly, GOES-19 will go into service as GOES-East, replacing GOES-16. In this location, GOES-19 will watch over most of North America, including the contiguous United States and Mexico, as well as Central and South America, the Caribbean, and the Atlantic Ocean to the west coast of Africa.* Live interviews are available June 25, 2024, between 6 a.m. - 1 p.m. EDT* Click here to request an interview: https://forms.gle/ny5wyq2mP52hQcyu7* Requests sent via the above form will have scheduling priority.

For nearly 50 years, NOAA and NASA have partnered to develop and advance NOAA’s geostationary satellites as part of the most sophisticated weather-observing, environmental monitoring, and space weather monitoring satellite system in the world.The first GOES satellite, GOES-1 (SMS-3), was launched in October of 1975. As groundbreaking as it was, it had limited capabilities and viewed Earth only about ten percent of the time. Each generation since the launch of GOES-1 has improved significantly, bringing with new capabilities and instruments. The most recent, and last generation is the GOES-R series that first launched in 2016 with GOES-R or GOES-16. This series came with new instruments such as the Geostationary Lightning Mapper (GLM) and the Advanced Baseline Imager (ABI). GOES-U, the final satellite of the series, also has the Compact Coronagraph-1 (CCOR-1) to monitor the Sun’s corona.After GOES-U launches, its successor will be a series called Geostationary Extended Observations, or GeoXO. The first satellite in the series is expected to launch in the early 2030s. GeoXO will continue NOAA’s five decades of critical Earth-observing data.

Scientists have observed the Earth’s lights at night for more than four decades using military satellites and astronaut photography; however, the view became significantly clearer after using satellite data from a low-light sensor onboard the Suomi National Polar-orbiting Partnership (NPP) satellite, launched in October 2011. The satellite’s Visible Infrared Imaging Radiometer Suite (VIIRS) “day-night band” can observe dim signals such as city lights (down to the scale of an isolated highway lamp), wildfires, gas flares, auroras, and reflected moonlight during nighttime hours. Swaths of VIIRS data are processed to find moonless, non-cloudy pixels. These “good” pixels are averaged at each location to produce a global image that depicts the Earth’s lights at night. Each pixel shows roughly 0.46 miles (742 meters) across.The top image, centered on France, is a composite of VIIRS data acquired between October 1, 2014 and April 30, 2015. Paris is visible just above the center of the image. North of Paris and across the English Channel (black), London is visible. The relatively dim Alps, characterized by their crescent-shaped geography, are speckled with lights from car headlights and lit roadways. South of the Alps several major cities in Italy are visible with the brightest spot being Milan. Rome is visible in the bottom right of the image. Strings and clusters of light out at sea are produced by ship lights. The second image, centered on France, is a composite of data from the Defense Meteorological Satellite Program (DMSP) Operational Linescan System (OLS) acquired during 2013. Each pixel shows roughly 1.86 miles (3 kilometers) across. The DMSP OLS night-lights data are available starting in 1992, and provide the ability to measure changes in light extent and locations over the past two decades.The image of Australia at night is a composite of VIIRS data acquired between January 1, 2015 and July 31, 2015. Major cities such as Brisbane, Sydney, Melbourne, and Perth are well lit along the coast. Alice Springs—situated in the geographic center of Australia—is some 1,500 kilometers from the nearest major city. Transient lights—those visible in only one monthly image—are colored red. These lights are mainly from brushfires burning during the dry season (May-July) in Australia’s Northern Territory and northern parts of Western Australia. Aside from fires, some of the transient lights could be attributed to natural gas flares, lightning, oil drilling, or mining operations. || ", "hits": 57 }, { "id": 4313, "url": "https://svs.gsfc.nasa.gov/4313/", "result_type": "Visualization", "release_date": "2015-10-12T00:00:00-04:00", "title": "Earth System Science Cartoon Schematic", "description": "Earth system science is composed of broad areas of study including: air, water, land, life, and solar. || system_sci10.0900_print.jpg (1024x576) [152.8 KB] || system_sci10.0900_thm.png (80x40) [6.5 KB] || system_sci_no_sun.webm (1920x1080) [2.2 MB] || system_sci_no_sun.mp4 (1920x1080) [18.0 MB] || without_sun (1920x1080) [32.0 KB] || system_sci_no_sun.m4v (640x360) [2.9 MB] || ", "hits": 39 }, { "id": 40247, "url": "https://svs.gsfc.nasa.gov/gallery/goes/", "result_type": "Gallery", "release_date": "2015-09-14T00:00:00-04:00", "title": "GOES", "description": "GOES (Geostationary Operational Environmental Satellites) is a joint mission between NOAA and NASA.

This allows them to maintain their positions over specific geographic regions so they can provide continuous coverage of that area over time.\n\nThe GOES-R series of satellites, designated with a letter during development and renamed with a number after reaching geostationary orbit, have transformed NOAA’s geostationary weather monitoring capabilities. \n\nGOES-R (now GOES-16) launched in 2016 and operates as NOAA’s GOES East satellite. GOES-S (now GOES-17), launched in 2018 and serves as an on-orbit backup. GOES-T (now GOES-18) launched in 2022 and is NOAA’s operational GOES West satellite. The final satellite in the series, GOES-U (GOES-19), was launched on June 25, 2024, and is slated to replace GOES-16 in the GOES East position by spring 2025.\n\nTogether, GOES East and GOES West 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. \n\nThe GOES-R Program is a collaborative effort between NOAA and NASA.

The outbursts, known as terrestrial gamma-ray flashes (TGFs), last only a few thousandths of a second, but their gamma rays rank among the highest-energy light that naturally occurs on Earth. The enhanced GBM discovery rate helped scientists show most TGFs also generate a strong burst of radio waves, a finding that will change how scientists study this poorly understood phenomenon.Lightning emits a broad range of very low frequency (VLF) radio waves, often heard as pop-and-crackle static when listening to AM radio. The World Wide Lightning Location Network (WWLLN), a research collaboration operated by the University of Washington in Seattle, routinely detects these radio signals and uses them to pinpoint the location of lightning discharges anywhere on the globe to within about 12 miles (20 km).Scientists have known for a long time TGFs were linked to strong VLF bursts, but they interpreted these signals as originating from lightning strokes somehow associated with the gamma-ray emission.\"Instead, we've found when a strong radio burst occurs almost simultaneously with a TGF, the radio emission is coming from the TGF itself,\" said co-author Michael Briggs, a member of the GBM team. The researchers identified much weaker radio bursts that occur up to several thousandths of a second before or after a TGF. They interpret these signals as intracloud lightning strokes related to, but not created by, the gamma-ray flash. Scientists suspect TGFs arise from the strong electric fields near the tops of thunderstorms. Under certain conditions, the field becomes strong enough that it drives a high-speed upward avalanche of electrons, which give off gamma rays when they are deflected by air molecules. \"What's new here is that the same electron avalanche likely responsible for the gamma-ray emission also produces the VLF radio bursts, and this gives us a new window into understanding this phenomenon,\" said Joseph Dwyer, a physics professor at the Florida Institute of Technology in Melbourne, Fla., and a member of the study team. Because the WWLLN radio positions are far more precise than those based on Fermi's orbit, scientists will develop a much clearer picture of where TGFs occur and perhaps which types of thunderstorms tend to produce them.Watch this video on YouTube. || ", "hits": 122 }, { "id": 4011, "url": "https://svs.gsfc.nasa.gov/4011/", "result_type": "Visualization", "release_date": "2012-11-28T00:00:00-05:00", "title": "United States Active Fires 2012", "description": "Records maintained by the National Interagency Fire Center (NIFC) and NASA both indicate that 2012 was an extraordinary year for wildfires in the United States.NIFC statistics show that more than 9.1 million acres had burned as of November 30, 2012—the third highest total in a record that dates back to 1960.

In 2009, Fermi detected gamma rays from a thunderstorm that was located well beyond the horizon from where it could directly observe the storm. So where did the rays come from? When antimatter collides with matter, the particles annihilate and emit gamma rays. This means the gamma rays detected by Fermi could only have come from an antimatter collision with the spacecraft itself, providing the first-ever clue that these Earth-bound storms can send antimatter into space.

Each lightning burst creates electromagnetic waves that begin to circle around Earth captured between Earth's surface and a boundary about 60 miles up. Some of the waves - if they have just the right wavelength - combine, increasing in strength, to create a repeating atmospheric heartbeat known as Schumann resonance. This resonance provides a useful tool to analyze Earth's weather, its electric environment, and to even help determine what types of atoms and molecules exist in Earth's atmosphere.The waves created by lightning do not look like the up and down waves of the ocean, but they still oscillate with regions of greater energy and lesser energy. These waves remain trapped inside an atmospheric ceiling created by the lower edge of the \"ionosphere\" - a part of the atmosphere filled with charged particles, which begins about 60 miles up into the sky. In this case, the sweet spot for resonance requires the wave to be as long (or twice, three times as long, etc) as the circumference of Earth. This is an extremely low frequency wave that can be as low as 8 Hertz (Hz) - some one hundred thousand times lower than the lowest frequency radio waves used to send signals to your AM/FM radio. As this wave flows around Earth, it hits itself again at the perfect spot such that the crests and troughs are aligned. Voila, waves acting in resonance with each other to pump up the original signal.While they'd been predicted in 1952, Schumann resonances were first measured reliably in the early 1960s.

The globe experiences lightning some 50 times a second, yet the details of what initiates this common occurrence and what effects it has on the atmosphere – lightning may be linked to incredibly powerful and energetic bursts called terrestrial gamma ray flashes, or TGFs — remains a mystery. In mid-November, a football-sized mission called Firefly, which is funded by the National Science Foundation, will launch into space to study lightning and these gamma ray flashes from above. The NSF CubeSat program represents a low cost access to space approach to performing high-quality, highly targeted science on a smaller budget than is typical of more comprehensive satellite projects, which have price tags starting at $100 million. The CubeSat Firefly, by focusing its science goals, will carry out its mission in a much smaller package and at a considerably lower cost. The Firefly mission also emphasizes student involvement as part of the ongoing effort to train the next generation of scientists and engineers. Students at Siena College, in Loudonville, N.Y., and the University of Maryland Eastern Shore, in Princess Anne, Md., were involved in all phases of the Firefly mission. The window for Firefly launch opens on Nov. 19, 2013, and it is scheduled to launch with 27 other cubesat missions, as well as a NASA experiment called the Total solar irradiance Calibration Transfer Experiment, or TCTE, which will continue measurements from space of the total energy output of the sun. || ", "hits": 53 }, { "id": 40043, "url": "https://svs.gsfc.nasa.gov/gallery/hurricane-resources/", "result_type": "Gallery", "release_date": "2010-03-08T00:00:00-05:00", "title": "Hurricane Resources", "description": "No description available.", "hits": 147 }, { "id": 40028, "url": "https://svs.gsfc.nasa.gov/gallery/hurricanesand-typhoons/", "result_type": "Gallery", "release_date": "2010-03-04T00:00:00-05:00", "title": "Hurricanes and Typhoons", "description": "A collection of data visualizations and imagery for tropical cyclones, including hurricanes and typhoons.\nFor more resources, visit the links below:\nNASA's Hurricane Page\n2018 Hurricane Archive\nPrecipitation Measurement Missions' Extreme Weather Page", "hits": 331 }, { "id": 10545, "url": "https://svs.gsfc.nasa.gov/10545/", "result_type": "Produced Video", "release_date": "2010-01-26T00:00:00-05:00", "title": "Black Hole Accretion Disc Energies", "description": "A black hole is a massive object whose gravitational field is so intense that nothing - not even light (electromagnetic radiation) — can escape from within its so-called event horizon.

It includes the human-initiated burning of vegetation for land clearing and land-use change as well as natural, lightning-induced fires. Scientists estimate that humans are responsible for about 90% of biomass burning with only a small percentage of natural fires contributing to the total amount of vegetation burned. Burning vegetation releases large amounts of particulates (solid carbon combustion particles) and gases, including greenhouse gases that help warm the Earth. Studies suggest that biomass burning has increased on a global scale over the last 100 years, and computer calculations indicate that a hotter Earth resulting from global warming will lead to more frequent and larger fires. Biomass burning particulates impact climate and can also affect human health when they are inhaled, causing respiratory problems. Here are three images of South America on October 7, 2004. The first image shows clouds and fires on that day. The second image is clouds and nitrous dioxide (NO2) concentrations in the stratosphere.
