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. 7 and 8, 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 3 datasets built from these; and the Level 3 Integrated Multi-satellitE Retrievals for GPM (IMERG). There will be a gap in data production for the GPROF GMI, DPR, and CORRA products while these updates are taking place, which could extend to several months.

Please visit the GPM Orbit Boost webpage for further details and updates.
