GPM V07 Update for Radiometer IC, GPROF and Combined

Effective on May 9, 2022, the GPM near real-time (NRT) algorithm will convert to V07. There are substantial format changes in the combined and GPROF products for all radiometers. The 1C product has some additions to the swath information. Depending upon how you read the 1C files, you may or may not have to make changes in your programs. Please click here for the GPM V07 file specification document, where all the format changes and their meaning are described. For those using GPROF and combined products, please read the file specifications. There were no calibration changes in GMI, but SSMIS 1C

GPM Satellite Data Outages During 23-24 March 2022

A mis-set error counter on the Core Observatory provoked a safe hold at 13:31:29 UTC on 23 March 2022, shutting down DPR and GMI observations. DPR and GMI were restored at 10:54 and 14:54 UTC, respectively on 24 March 2022. No data were recoverable from the outage period, although IMERG Early and Late continued to be produced (without GMI input, of course). The same will be true for the Final Run when it is produced. An outage at FNMOC prevented transmission of DMSP (SSMIS) from 15:51 UTC 23 March 23 to 00:47 UTC 24 March 2022. Gaps in the data are: F16: 14:34:07-19:29:39, F17: 14:56:24-19:46

IMERG Catches Australian "Rain Bomb"

IMERG Rainfall Totals from Australian :"Rain Bomb" in March 2022
Thursday, March 3, 2022
The below animation shows surface rainfall estimates from NASA’s IMERG multi-satellite precipitation product for the week starting on Feb. 22, 2022 at 0000 UTC and ending on Feb. 28, 2022 at 2330 UTC. Areas shaded in blue and yellow show three-hour average snapshots of IMERG rain rates every half-hour overlaid on cloudiness (shown in white/gray) based on geosynchronous satellite infrared observations. Below the rain rates and cloudiness data, IMERG rainfall accumulations are shown in green and purple. Tropical Cyclone Anika’s track is shown with a gray line based on data from the U.S. Navy-Air
