IMERG V07 Early and Late Run Extreme Values in October 2024

The PPS has completed retroprocessing IMERG V07 products for Jan. 1, 1998 to May 31, 2000. Both the Early and Late standard HDF product and the GIS products are available on the "jsimpson" GPM near real-time file servers. Please visit our data directory for a full list of product downloads and documentation. With this retroprocessing now complete, IMERG V07 products are now available from January 1998 through the present.

New Tool for Visualizing IMERG Data

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

IMERG V07 Early and Late Run Extreme Values in October 2024

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
