How much it rained (GPM microwave, monthly, climate-tuned)

GPM GMI (GPROF) Climate-based Radiometer Precipitation Profiling L3 1 month 0.25 degree x 0.25 degree V07 (GPM_3GPROFGPMGMI_CLIM) at GES DISC
atmosphere NASA GES_DISC Level 3 active
In plain English

What it measures. Monthly global averages of how much it rained, combining microwave precipitation estimates from multiple satellites onto a quarter-degree grid. This is a 'climate' version tuned for a consistent long-term record.

How it's made. Produced by the GPROF algorithm using GPM's GMI microwave sensor and partner sensors, with a homogeneous reanalysis dataset (ECMWF-Interim) used as background so the record stays consistent over the years.

How & where you'd use it. Designed for climate studies that need a steady, comparable record of global precipitation over long time spans.

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 Older versions will no longer be available and have been superseded by Version 07. The "CLIM" products differ from their "regular" counterparts (without the "CLIM" in the name) by the ancillary data they use. They are Climate-Reference products, which requires homogeneous ancillary data over the climate time series. Hence, the ECMWF-Interim (European Centre for Medium-Range Weather Forecasts, 2-3 months lag behind the regular production) reanalysis is used as ancillary data to derive surface and atmospheric conditions required by the GPROF algorithm for the "CLIM" output. The GPROF databases are also adjusted accordingly for these climate-referenced retrievals. 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.
