Daily rainfall estimated from microwave readings (F18)

GPM SSMIS on F18 (GPROF) Radiometer Precipitation Profiling L3 1 day 0.25 degree x 0.25 degree V07 (GPM_3GPROFF18SSMIS_DAY) at GES DISC
atmosphere NASA GES_DISC Level 3 active
In plain English

What it measures. Daily, gridded global rainfall amounts averaged onto a quarter-degree map, suitable for climate work.

How it's made. Produced by the GPROF algorithm using microwave readings from the SSMIS instrument on the DMSP F18 satellite, which senses both liquid and frozen precipitation, then combined into daily grid averages.

How & where you'd use it. One contributor to the merged, multi-satellite record of global precipitation used for climate studies.

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 Older versions will no longer be available and have been superseded by Version 07. 3GPROF products provide global gridded monthly/daily precipitation averages from multiple satellites that can be used for climate studies.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.
