Daily rainfall estimated from microwave readings (GPM)

GPM GMI (GPROF) Radiometer Precipitation Profiling L3 1 day 0.25 degree x 0.25 degree V07 (GPM_3GPROFGPMGMI_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 observed by the GPM satellite's main microwave imager.

How it's made. Produced by NASA's GPROF algorithm from the GMI microwave imager aboard GPM, gridded to roughly 25 km cells.

How & where you'd use it. Supports climate research and monitoring of worldwide precipitation patterns, sensitive to both liquid and frozen 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 Older versions will no longer be available and have been superseded by Version 07. 3GPROF products provide global gridded monthly/daily precipitation averages from multiple satellites that can be used for climate studies.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.
