IMERG V07 Final Run Retrospective Processing Completed

As of Aug. 30, 2023, the entire available record of archived TRMM, GPM Core Observatory, partner satellite, and ancillary data has been retrospectively processed for the IMERG V07 Final Run dataset, covering June 2000 - April 2023. Initial processing (i.e., with newly arrived data) will extend the Final Run record as additional months of data are received, typically 3.5 months after the near real-time products, which users can determine by checking the IMERG Final Run data listings on the PPS or GES DISC GPM data sources (a full listing of GPM data downloads and sources can be found in the GPM

GPM L3 GPROF Daily and Monthly and L3 CLIM GPROF products will be updated to V07C on September 07, 2023

Commencing with the data date of Friday September 1, 2023 all GPM L3 GPROF Daily and Monthly products will be updated to the designation V07C. PPS will be making these V07C products available to the public starting on Thursday September 7, 2023. The L3 CLIM GPROF data products will also be updated on Thursday September 7, 2023. These products will commence with the data start date of Thursday June 1, 2023 and also have the designation V07C. This version update is necessary to correct the L3 gridded vertical hydrometeor profile means over the high latitude regions. This update identifies pixels

IMPORTANT: Errors in GPROF Orbits within Select IMERG Final Data Products

The IMERG development team has become aware that a small number of isolated bad Level 2 GPROF orbit granules leaked into V07A IMERG Final Run processing. The team is working with PPS to identify a more-complete list of such instances and trace them back to the Level 1C microwave data. Additional testing is being done and might reveal a few more cases. We are providing this information now in case the times happen to impinge on a detailed study that you are performing. The above image is an example of one of the worse cases (from F16 SSMIS); most cases are less severe or shorter in duration and

GPM Views Typhoon Bolaven

GPM Overpass of Cyclone Bolaven
Thursday, October 12, 2023
Typhoon Bolaven began as a tropical depression over the West Pacific Ocean on Oct. 7, 2023. On Oct. 10, Bolaven became a Typhoon and passed over the Mariana Islands as it tracked to the northwest. Bolaven then rapidly intensified over 12 hours from a Category 1 to a Category 5 storm on the Saffir-Simpson scale, starting around 12 UTC on Oct. 10. Several factors contributed to the rapid intensification, including modest shear in the atmosphere and warm sea-surface temperatures. This animation shows precipitation within Typhoon Bolaven around the time that rapid intensification began. The global
