Rainfall amounts every 3 hours (TRMM)

TMI/TRMM precipitation and uncertainty (TMPA) L3 3 hour 0.25 degree x 0.25 degree V001 (WC_MULTISEN_PREC_025) at GES DISC
atmosphere NASA GES_DISC Level 3
In plain English

What it measures. How much rain fell every three hours across the tropics and subtropics (from 50 degrees north to 50 degrees south), over both land and ocean, along with an estimate of how uncertain each rainfall figure is.

How it's made. Combines readings from the TRMM rainfall satellite with many other weather satellites, blended onto a quarter-degree global grid.

How & where you'd use it. Good for studying rainfall patterns, floods, and droughts in tropical regions, with the bonus of knowing how reliable each estimate is.

Official description

TMI/TRMM precipitation and uncertainty (TMPA) L3 3 hour 0.25 degree x 0.25 degree V001 provides estimates of accumulated precipitation from the Tropical Rainfall Measuring Mission (TRMM) and Other Data Precipitation Data Set (TRMM 3B42; Huffman et al., 2007), along with estimates of the uncertainty in the TRMM 3B42 made by Bytheway and Kummerow (2013). The data set covers both ocean and land from 50 degree North to 50 degree South.
