Florida hurricane season: Science behind satellite images of tropical storm sizes
To us here on Earth, most of us never give a second thought to satellites, which may appear like small shining stars among many in the night sky – if they appear at all. But as hurricane season approaches in Florida, satellites will get a detailed view of our planet from far away. From all the way up in orbit, the spacecrafts provide a critical tool for scientists and other officials to monitor the development of tropical storms and keep the public informed about incoming danger. While hurricane season doesn't begin until June 1, the National Oceanic and Atmospheric Administration (NOAA) has already started its daily tropical outlooks – highlighting areas showing potential for tropical development within about a week's time. That means its National Hurricane Center will turn to its fleet of orbital satellites for data, which can keep an eye on tropical storms much more effectively than land-based observations alone. First introduced in 1975, geostationary satellites have become a standard instrument for weather forecasting, especially during the Atlantic hurricane season, win runs June 1 to Nov. 30 every year. Technology has greatly improved in the decades since, enabling the satellites to relay data faster back to Earth while transmitting better quality images and storm detection details. Geostationary satellites orbit Earth at a speed allowing them to stay fixed over the same area of the planet so they can continuously monitor a tropical storm and its development. NOAA is responsible for the GOES satellites that are constantly monitoring Earth for weather threats. The latest among them, the GOES-U satellite, launched in June 2024 from Kennedy Space Center near Cape Canaveral, Florida. The GOES-U satellite – Geostationary Operational Environmental Satellite U – is designed to not only enable earlier storm detection, but also give forecasters more time to warn the public. Images from the GOES satellites reach NOAA at about five-minute intervals. But the next generation of satellites the agency is planning − GeoXO − will see the forecasting capabilities improve even further. The GOES-U satellite was due to become operational in spring 2025 after undergoing a test period in fall 2024. The last in NOAA's current series of satellites known as GOES-R − named after the first satellite of the series − the satellite is improved over previous iterations to detect not only a weather system's structure but its exact location. Those capabilities should prove crucial during hurricane season, when GOES-U and other satellites will play a critical role in Florida's early warning system, Michael Brennan, director of the NOAA National Hurricane Center in Miami, previously told FLORIDA TODAY, a USA TODAY Network newspaper. "Satellite imagery is our first line of defense against hurricanes," Brennan said. "It's how we monitor systems that develop, it's how we estimate how strong they are before we can fly an aircraft into them." It's not just satellites that can monitor hurricanes from high in the sky. NASA's International Space Station, which orbits Earth from around 250 miles high, also routinely captures imagery of tropical storms and hurricanes that provide a striking bird's-eye view. For instance, as Hurricane Milton moved in on Florida in October 2024, the U.S space agency released photos and a timelapse video showing the eye of the storm as it churned and swirled its way toward the coast. External cameras on the International Space Station first captured a glimpse of the gathering tempest Oct. 7 while orbiting above Florida. At the time, the Category 5 storm was packing winds of 175 mph as it moved across the Gulf of Mexico, later renamed by the U.S. government as the Gulf of America.

The newest GOES weather satellite in NOAA's fleet is now fully operational (video)
When you buy through links on our articles, Future and its syndication partners may earn a commission. The final satellite in NOAA's GOES-R weather satellite series has a new place in orbit … and a new name. The GOES-19 weather satellite, which launched into orbit in June 2024, has officially taken the place of its predecessor GOES-16 to watch over the Western Hemisphere from its perch 22,236 miles (35,785 kilometers) above us. To mark the milestone, the satellite has the new name of GOES East to serve as the dominant geostationary satellite in the fleet, NOAA officials said in a statement. "With GOES-19 now in operation, NOAA has delivered the full fleet of GOES-R satellites to orbit, providing the most sophisticated technology ever flown in space to help forecast weather on Earth," said Stephen Volz, assistant administrator for NOAA's Satellite and Information Service, in the statement. "GOES-19 supports NOAA's mission to provide secure and timely access to global environmental data and information to promote and protect the nation's security, environment, economy and quality of life." As GOES East, the satellite will be responsible for keeping a watchful eye on tropical development in the Atlantic Ocean, and monitor weather such as severe storms, wildfires, and atmospheric rivers. Just like its siblings, GOES-19 is equipped with technology to produce high-resolution imagery, take measurements of the atmosphere, and track the location and intensity of lightning in real-time. If that's not exciting enough for scientists, this satellite also hosts NOAA's first compact coronagraph instrument (CCOR-1), monitoring the sun's activity. "CCOR-1 is a game-changer for ensuring our nation is resilient to solar storms, monitoring massive eruptions of energy from the sun in real time," Clinton Wallace, director of NOAA's Space Weather Prediction Center, said in the statement. "With dramatically improved resolution and faster detection, it helps us better predict dangerous space weather that can impact satellites, GPS, astronaut safety, aviation and power grids, ensuring we can protect critical technology and infrastructure like never before."

Next-gen NOAA weather satellite giving meteorologists big forecasting edge
After launching in June 2024, a brand new weather satellite is finally up and running. "I don't know what the right word is, but it sort of, it completes something I've been working on my entire career," said Dan Lindsey, the GOES-R program scientist at NOAA. GOES-19 began its trip to space last summer and since then, scientists like Lindsey, who oversee the program, have been making sure it's ready to go. "They have to make sure it's pointing in the right direction. It has to make sure that everything is lined up the way we want. And then all seven of those instruments have to be individually tested. They're turned on. Their sample data is collected," Lindsey said. With those tests going smoothly, GOES-19 is officially watching over us as GOES-East. Many of the instruments on board, like the advanced baseline imager and lightning mapper look down at storms on earth, creating various loops helping NEXT Weather meteorologists prepare your forecasts. But this satellite has an extra tool: the compact coronagraph. That looks up at the sun to help track solar storms, which give us the beautiful northern lights, but can also cause radio blackouts and power outages. "It sort of blocks out the sun itself and allows us to take pictures of that corona. And that allows us to detect these coronal mass ejections and predict when they're going to impact the Earth," Lindsey said. He says all of last year's solar storms were perfect for testing. And even with all the buzz around this new gadget, there's already a lot of hype about what's next to improve weather forecasting. "The future series is called GeoXO, or Geostationary Extended Observations, launching in 2032. We're going to go from two spacecraft to three, and add some new instrumentation and also make some improvements to our existing imager and lightning mapper capabilities," Lindsey said. This new satellite will help meteorologists track hurricanes, thunderstorms and winter storms well into the 2030s until the next generation of satellites are ready to go.

NOAA's most advanced weather monitoring system will be operational soon
Has anyone noticed some weird/missing data from satellite imagery over the past few weeks? There's a reason for that! The old satellite that has been used for years is moving, with the most state-of-the-art satellite set to replace it. Basically, all of the images that are taken from space come from satellites, machines that are launched into space and orbit Earth, or another object and send back information. The National Oceanic and Atmospheric Administration and NASA collaborated on the sophisticated Geostationary Operational Environmental Satellites, also known as GOES-R Series. Now, for those wondering, what in the world is a Geostationary Operational Environmental Satellite? It's a satellite that sits above the equator at a speed matching the Earth's rotation, which allows it to constantly view the same area of the Earth at all times. There are four satellites in the GOES-R series, with its coverage spanning from the west coast of Africa to New Zealand and from near the Arctic Circle to the Antarctic Circle — the last of which (GOES-19) will become operational April 7, 2025. The GOES-R Series imager scans the Earth five times faster with four times the resolution and three times the number of channels than previous satellites for more accurate and reliable forecasts/severe weather warnings. The imager provides images of weather patterns, hurricanes and severe storms as frequently as every 30 seconds. And there are various other benefits from the GOES-R. GOES-16 was launched in 2016 and has been operational ever since for the eastern half of the US. GOES-17 was launched in 2018 as an on-orbit backup. GOES-18 was launched in 2022 and now serves as the operational satellite for the western half of the US. GOES-19 was launched in 2024 and is slated to take over GOES-16 as the main operational satellite for the eastern half of the United States, while GOES-16 becomes the on-orbit backup. During the few weeks it took for GOES-16 and GOES-19 to drift into their new positions, some of the normally flawless satellite images coming from GOES-16 were degraded, which is the reason it looked all wonky/weird earlier. The satellite images will likely no longer be degraded as of Monday when the new GOES-19 satellite officially replaces the old one. But why does this matter? Satellites are the main source of critical atmospheric, hydrologic, oceanic, climatic, solar and space data. GOES-19 is the culmination of nearly five decades of research, with its primary instrument being the ABI. It's the most advanced weather-observing and environmental monitoring system, providing enhanced imagery and atmospheric measurements, real-time mapping of lightning activity, and space weather observations. The ABI is a tool that can view Earth with sixteen different channels, each measuring energy at different wavelengths along the electromagnetic spectrum to obtain information about Earth's atmosphere, land, and ocean. There's also a brand new instrument, the Compact Coronagraph-1 (CCOR), which will support NOAA's Space Weather Follow On (SWFO) mission. It will be the nation's first operational coronagraph and will serve as the primary source for information about impending geomagnetic storm conditions, allowing the Space Weather Prediction Center to issue warnings one to four days in advance. Tools like these significantly improve detection and observation of environmental phenomena that directly affect public safety, protection of property, and our nation's economic health and prosperity.
