05/16/2024 - On June 03, 2024 PPS will update the GPM Near-realtime (NRT) subsystem to RHEL8 OS. Please read all the details and possible impacts here.

03/04/2024 - On March 08, 2024 after PPS's production system conversion to RHEL 8, PPS will restart GPM radar production processing at version V07C for the post boost radar data. Click here for details.

02/26/2024 - PPS releases 'tkio-3.101.' Click here for details.

02/14/2024 - From Monday March 04, 2024 to Wednesday March 06, 2024, PPS will not distribute the data of GPM and its partners. Click here for details.

01/18/2024 - V07B IMERG Final Run Retrospective Processing Completed. Click here for details.

12/12/2023 - On December 12, 2023, PPS will start to create the Version 07B Final IMERG product. This reprocessing will correct the anomalous precipitation found in some V07A Final IMERG files due to bad input data. Click here for details.

12/02/2023 - The GPM satellite experienced an anomaly and went into Safe Mode around 00:40 UTC on December 2, 2023 or (19:40 EST December 1, 2023). The GPM satellite has returned to Mission Science Mode. The DPR Ku/Ka radars have returned to operational science mode and are collecting data as of 16:41UTC on December 05, 2023. GPM data will be released after the products are verified by the science team. Note that post-boost DPR data continues to be held from public distribution. Updates will be posted to this website as important details are provided.

11/08/2023 - The GPM Core Satellite Boost (Nov 07-08, 2023) to the new orbit altitude has completed. Everything is nominal. (Please see GMI Footprint Changes Due to 35 km Altitude Boost). The GPM DPR instrument data will take more time to evaluate in detail. Updates will be posted as important information becomes available.

10/24/2023 - The GPM Core Observatory satellite is scheduled to undergo a series of orbit boost maneuvers which will raise its altitude from 400km to 435km. Tentatively scheduled for Nov. 7 and 8, 2023, the goal of these boosts is to restore the GPM Core Observatory's lifespan closer to the original estimates of ending in the early 2030s. Please read our announcement and check for the latest updates on the GPM orbit boost maneuver here for all details.

10/23/2023 - After a small number of bad GPROF orbit granules were detected in the V07 IMERG Final Run products, the GPM L1 science team identified a list of bad input data that led to the anomalous processing of 1C and downstream V07 products. PPS plans to roll back and retrospectively process the affected L1 data, L2 GPROF data and the corresponding L3 daily and monthly GPROF data. The retro-processed data will be released by Friday October 27, 2023. Click here for more information.

10/20/2023 - There will be a temporary delay in GPM science products beginning on 10/19/2023 at 14:10:07 UTC while we recover from a satellite data anomaly. All GPM core satellite instruments are functioning normally and data has resumed to the ground system. We anticipate some data loss on 10/19/2023 and will log the affected science products here. Our expectation is that we will release all products and return to normal data flow early next week.

10/18/2023 - 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 - May 2023. Click here for details.

10/04/2023 - 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. See details here and a list of bad IMERG V07 Final Data here. A worst-case example from F16 SSMIS can be seen here.

08/30/2023 - GPM L3 GPROF Daily and Monthly products and L3 CLIM GPROF products will be updated to V07C on September 07, 2023.

07/06/2023 - On Monday July 10, 2023, PPS will begin to generate IMERG Version 07 Final data products. In the coming few months, PPS will create Version 07 Final IMERG files for the entire period of record, which starts in June 2000.

06/16/2023 - Starting Tuesday June 20, 2023, PPS will process and release new satellite NOAA21 ATMS GPM level 1C and GPROF level 2 and level 3 data and climatology products. These new products will have the starting date of February 1, 2023. Click here for details

06/02/2023 - On Thursday July 06, 2023, PPS will commence processing GPM Level 2 and Level 3 data products as V07B for data starting Saturday July 01, 2023. Click here for details.

04/19/2023 - On Tuesday April 18, 2023 at 12:00 UTC the GPM Flight Operations Team uploaded a firmware update to the GPM satellite. During this time the instruments were shut down and the spacecraft was put into sun acquisition mode. No science data was available during this time. On Wednesday April 19, 2023 nominal PPS operations were restored. Click here for details.

See the resulting list of partial and empty granules here.
