Nov. 14, 2024, 8:00 p.m. ET 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!

SSMIS Outage Has Ended

A server upgrade at the Fleet Numerical Meteorology and Oceanography Center (FNMOC) interrupted real-time transmission of Defense Meteorological Satellite Program (DMSP) data on Sept. 11, 2024, for the F16, F17, and F18 satellites at 18:28, 19:03, and 19:36 UTC, respectively. They returned to real-time operation on Sept. 18 at 23:45 UTC, and are believed to be back-filling the missed data. Thus, the IMERG Final Run products should be unaffected, but the Early and Late Run products will lack SSMIS for this period, with some variation due to latency considerations.
3D map of GPM precipitation estimates from within Hurricane Francine as it approached the Gulf Coast.
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

Fix to the Metadata of IMERG Climatology GeoTIFF Files

Recently, an error in the metadata of the GeoTIFF files for the IMERG V07B Final Run climatologies has been discovered. This error affected only the geolocation, specifically the orientation, of the fields and not the precipitation data. These files have been replaced with ones containing the correct metadata. Users who have downloaded the old GeoTIFF files should replace them with the new files. These IMERG climatology files are available at https://gpm.nasa.gov/data/imerg/precipitation-climatology
