How much it rained, climate-tuned (TRMM, daily)

GPM TMI on TRMM (GPROF) Climate-based Radiometer Precipitation Profiling L3 1 day 0.25 degree x 0.25 degree V07 (GPM_3GPROFTRMMTMI_DAY_CLIM) at GES DISC
atmosphere NASA GES_DISC Level 3
In plain English

What it measures. Daily rainfall amounts averaged onto a quarter-degree global grid, in a version specially tuned for studying climate over long time spans.

How it's made. Built from the TMI microwave sensor on the TRMM satellite using the GPROF rainfall algorithm, with consistent reanalysis weather data used as background so the record stays uniform over time.

How & where you'd use it. Suited for climate studies that compare rainfall across many years, where consistency matters more than the very latest data.

Official description

This a new (GPM-formated) TRMM product. There is no equivalent in the old TRMM suite of products. 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 Older versions will no longer be available and have been superseded by Version 07.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.
