ANNOUNCING a NEW IMERG Web Visualization Tool: RAIN-Global (Regional Animations of IMERG in Near-realtime - Global Edition): https://storm.pps.eosdis.nasa.gov/storm/outreach/RAIN-Global.html RAIN-Global is the next-generation, 3D global, fully interactive upgrade to RAIN, a web interface that displays recent 7-day animations of precipitation rates and accumulations from IMERG-Late data, as well as cloudiness from geosynchronous IR data. Animations are updated daily for the 7-day period ending on the prior day and are available for the past 30 days. New features include: Use your mouse or...

Regions of unrealistically high values appeared in the IMERG Early and Late files starting around 00:00 UTC on 17 October 2024. Upon investigation, GPM scientists detected an operational problem on the GPM Core Observatory around 15 October 2024 that caused some corrupted CORRA data to be added to the CORRA-GMI calibration accumulator files for the IMERG Early and Late Runs. These anomalous data affected the calibration when it was next updated (on 17 October 2024). Repaired calibration files were applied at 06:00 UTC on 2 November 2024. The time spans of the unrealistic calibrations in Early...
On 18 October 2024 PPS received a corrupted IR file for 15:00 UTC, which caused all subsequent IR processing to fail and not contribute to the Early Run from 16:00 UTC on 18 October until 05:00 UTC on 20 October, and to the Late Run from 16:00 UTC on 18 October until 20:00 UTC on October 19. Subsequently, PPS manually skipped past the defective IR data file and ran all the IR data that were missed, and then reran both Early and Late for the periods listed above. These rerun products have replaced the earlier products on the fileserver. Please note the out-of-order file times to confirm which...
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.
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
