For the Final Run, the V07 record ends in September 2025 because the parent products feeding into the IMERG algorithm (CORRA and GPROF) are being upgraded to V08. If processing were to go beyond September, the Final record would have to use V08 inputs instead of V07 inputs. Since the IMERG V07 code is configured with the expectation of V07 inputs, this would introduce potential discontinuities in the Final record. The IMERG V08 Final Run is planned for release in the summer of 2026, though this timeline assumes that V08 of the parent products behaves within expected bounds. When this release...

On Tuesday, 20 January 2026, NASA's Precipitation Processing System (PPS) will temporarily shutdown the GPM Near Real-time (NRT) system at 18:00 EST (23:00 UTC). This is necessary to complete the move of data from the current high-speed storage system (not currently under maintenance) to the new storage system that is under maintenance. It will take approximately 14 hours to finalize the synchronization of the data from the old storage to the new one. During this 14 hours no new data will be produced or ingested. While user access to the file server (jsimpson.pps.eosdis.nasa.gov and...

Department of Defense officials have reached an agreement to continue sharing DMSP SSMIS data until the sensor fails, or until the program formally ends (currently planned for September 2026). This decision puts off for now the impacts that the previously announced SSMIS shutdown would have had on the IMERG product.

It was announced on Monday, June 30, that NASA requested and it was agreed to postpone the removal of SSMIS data and to continue processing and distributing DMSP data through July 31.

Department of Defense (DOD) FNMOC has announced its intention to shut down the current flow of operational SSMIS data on 30 June 2025. This is much earlier than the earlier announced date of September 2026, and would suspend the use of F16, F17, and F18 SSMIS data in GPM PPS. We are vigorously pursuing alternatives for continuing access to SSMIS data, but it seems likely that there will be an interruption, and perhaps end, to the SSMIS data streams. The lack of these 3 conically scanning radiometers will impact the accuracy of all IMERG products as they will have data from 3 fewer radiometers...
