While the GPM Core Observatory’s instruments show exceptional detail in Milton’s rainfall structure in several overpasses throughout the week, the IMERG global multi-satellite product provides a broader overview of precipitation along Milton’s track as a continuous picture from development through landfall. Download this video (right-click -> "save as") The above animation shows IMERG precipitation rates (in blue/yellow shading) and accumulations (in green/purple shading) from Oct. 5-10, 2024. Cloudiness is shown in shades of white/gray using infrared geosynchronous satellite data. While

Updated Oct. 10, 2024 Click here for a visualization of IMERG precipitations and totals from Hurricane Milton. After forming in the Bay of Campeche, Hurricane Milton underwent a remarkable period of rapid intensification with its central pressure falling from 1007 mb (29.74 inches of mercury, inHg) at 11:00 a.m. EDT Oct. 5 to 897 mb (26.49 inHg) at 8:00 p.m. EDT on Oct. 7. At this time Milton became the fifth most intense hurricane in the Atlantic Basin on record in terms of central pressure, just behind Hurricane Rita (2005) on that list, and only the sixth storm in the Atlantic to have a

After tracking through the eastern Gulf of Mexico and battering much of the west coast of Florida with strong winds and storm surge, Hurricane Helene made landfall in the Big Bend region of Florida’s northwest coast at 11:10 pm EDT about 10 miles west-southwest of Perry, Florida, as a powerful Category 4 hurricane with maximum sustained winds reported at 140 mph by the National Hurricane Center (NHC). Hurricane Idalia, a strong Category 3 storm at the time, also made landfall in the Big Bend last year. Animation of NASA IMERG precipitation rates and totals from Hurricane Helene from Sept. 23 -

[ Goto Spanish translation; Ir a la traducción al español ] On Monday evening, Sept. 23, 2024, an unusual hurricane struck southern Mexico, dumping 20 inches of rainfall along the coast according to estimates from NASA's IMERG precipitation product. The following image shows these rainfall estimates: Click here for a full resolution version of this image. Observations from an international constellation of satellites were the starting point for calculating these estimates, and the data confirm that forecasters in prior days were right to warn of possible heavy rainfall. Forecasters did have

Nov. 14, 2024, 8:00 p.m. ET Register Here Overview As we finish celebrating the NASA / JAXA Global Precipitation Measurement (GPM) mission's 10 year anniversary, we'll take a look behind the scenes at how the GPM Outreach Team showcased the mission's science, technology, and applications over the years. We'll also look ahead to the exciting new plans for the future of NASA’s precipitation measurement missions! Speakers Kristen Weaver Kristen Weaver is the Deputy Coordinator for the GLOBE Observer project, which aims to extend the long-standing citizen science and science education program

Updated: Wednesday, September 18, 2024 Hurricane Francine made landfall on Wednesday, September 11, at 5:00 p.m. CDT on the southern coast of Louisiana, approximately 30 miles south-southwest of Morgan City. The National Hurricane Center (NHC) classified it as a Category 2 storm, with maximum sustained winds estimated at 100 mph. Francine originated from a westward-moving tropical wave of low pressure, known as an African easterly wave. This wave, as is typical, emerged off the west coast of Africa before traversing the tropical Atlantic and Caribbean. These waves often serve as seedlings for

Oct 10, 2024, 8:00 p.m. ET Overview It is amazing that NASA’s Earth-observing satellites can collect data from around the globe to help us better understand and protect our home planet! Have you ever wondered how we compare the data we obtain from satellites with data we collect on the ground to ensure that satellites are accurate with their measurements? Join us to learn about ground validation efforts that must be completed to ensure that our global precipitation data is accurate. You will also learn how you can contribute to the vast array of freely available NASA-sponsored data through The

Did you know that GPM data has enabled people to better understand how water moves through our planet and make informed decisions that lead to improved outcomes for society? GPM continues to support a range of applications from water resource management, agriculture, vector- and water-borne disease monitoring, animal migration, tropical cyclone location and intensity estimation, hydropower management, flood and landslide monitoring and forecasting, and land system modeling, among others. Join us during this free webinar to learn about the multiple ways GPM is used throughout the world and gain a perspective from two GPM power users that help support weather forecasters and the ecological community.

On the morning of Sunday, June 30, Hurricane Beryl became a rare early season major hurricane when it reached Category 3 status with sustained winds of 115 mph as it was moving across the Atlantic 420 miles east-southeast of Barbados in the direction of the Leeward Islands. Then, just a few hours later at 11:35 a.m. EDT, Beryl became the earliest Category 4 hurricane on record in the Atlantic with sustained winds reported at 130 mph by the National Hurricane Center (NHC), surpassing Hurricane Dennis from the epic 2005 Atlantic hurricane season. Beryl also became historic as the strongest and

Have you ever wondered how Earth observing satellites are able to measure things like precipitation, temperature, and other phenomenon from space? Join us during this free webinar to learn about “remote sensing” and gain an understanding of how and why we use satellites to help us understand and protect our home planet.
