Daily rainfall estimated from microwave readings (NOAA-21)

GPM ATMS on NOAA-21 (GPROF) Radiometer Precipitation Profiling L3 1 day 0.25 degree x 0.25 degree V07 (GPM_3GPROFNOAA21ATMS_DAY) at GES DISC
atmosphere NASA GES_DISC Level 3 active
In plain English

What it measures. Daily average rainfall on a global grid, summarizing precipitation detected by a microwave sounder.

How it's made. Produced by NASA's GPROF algorithm from the ATMS microwave sounder on the NOAA-21 satellite, gridded to roughly 25 km cells.

How & where you'd use it. Helpful for climate studies and global precipitation monitoring, capturing both liquid rain and ice-phase precipitation.

Official description

Version 07 is the current version of the data set. Older versions will no longer be available and have been superseded by Version 07. 3GPROF products provide global gridded monthly/daily precipitation averages from multiple satellites that can be used for climate studies. The 3GPROF products are based on retrievals from high-quality microwave sensors, which are sensitive to liquid and ice-phase precipitation hydrometeors in the atmosphere.
