GPM PR and TMI on TRMM Combined Precipitation L2B 1.5 hours 5 km V07 (GPM_2BCMB_TRMM) at GES DISC

Metadata Updated: December 6, 2023

This is the new (GPM-formated) TRMM product. It replaces the old TRMM_2B31

This is the GPM-like formatted TRMM Combined Precipitation (TRMM Ku radar and microwave radiometer/imager), first released with the "V8" TRMM reprocessing.

Gombined Radar-Radiometer Algorithm performs two basic functions:

First, it provides, in principle, the most accurate, high resolution estimates of surface rainfall rate and precipitation vertical distributions that can be achieved from a spaceborne platform, and it is therefore valuable for applications where information regarding instantaneous storm structure are vital.

Second, a global, representative collection of combined algorithm estimates will yield a single common reference dataset that can be used to “cross-calibrate” rain rate estimates from all of the passive microwave radiometers in the TRMM and GPM constellations.

The cross-calibration of radiometer estimates is crucial for developing a consistent, high time-resolution precipitation record for climate science and prediction model validation applications.
