The GPM Core Observatory satellite is scheduled to undergo a series of orbit boost maneuvers which will raise its altitude from 400km to 435km. These boosts are tentatively scheduled for Nov. 8 and 10, 2023. As a result of these maneuvers, the observing parameters of data collected by the GPM Microwave Imager ( GMI ) and Dual-frequency Precipitation Radar ( DPR ) instruments will change, including the footprint sizes and Earth incidence angle. The algorithms which process these data must be updated to accommodate these changes, including the Level 2 GPROF, DPR, and CORRA algorithms; the Level...

Retrospective processing of IMERG V07 Final Run has commenced as of July 2023 using the new IMERG V07 algorithm. The TRMM and GPM eras are being processed in parallel, starting at the beginning of each dataset, with a projected end date no later than Nov. 2023. IMERG V06 and V07 are sufficiently different that users are discouraged from mixing data from the two versions. V07 Early and Late Run processing will commence after the Final Run is completed. The projected timeline for IMERG V07 processing is shown in the figure below. IMERG download links are listed on the GPM website Data Directory...

PPS has begun to generate the IMERG V07 Final data product. In the coming months, PPS will create IMERG V07 Final files for the entire period of record, which starts in June 2000. PPS will finish reprocessing Version 07 Final IMERG before starting to generate the V07 near real-time (NRT) IMERG data products. The NRT IMERG data products are IMERG Early (with 4-hour latency) and IMERG Late (with 14-hour latency). Early and Late IMERG reprocessing is currently scheduled to begin in November 2023, and it will take PPS several months to create the full period of record (June 2000 to present)...

The IMERG algorithm team has finalized the IMERG V07 algorithm for the final product. This is the one that is generated with a 3 month latency. PPS has started the reprocessing and processing of V07 IMERG final. The V07 reprocessed final files will soon be available from PPS. The algorithm team has requested that the entire TRMM/GPM era IMERG-final product be reprocessed before the near real-time (NRT) early (4 hour latency) or late (14 hour latency) products are produced at V07. This will allow them to use the final IMERG product to update ancillary files used as part of the early and late...

Commencing with the data date of Saturday July 1, 2023, all GPM Level 2 and Level 3 data products will be updated to the designation V07B. PPS will be making these V07B data products available to the public starting on Thursday July 06, 2023. This version update is necessary since there has been a change to the GPM autosnow input data for these GPM Level 2 and Level 3 algorithms. PPS GPM Level 2 and Level 3 data processing will be on hold between Sat July 01 -Tue July 04, 2023 in order to close out the GPM Level 2 and Level 3 V07A products through June 30, 2023. On Wed July 05, 2023 we will...
