Quality arrays have been set aside in the files to be populated in the future, once the characteristics of the sensor become better understood and enhancements are made to the science algorithms. Quality indicators will be available for each 5 degree gridbox in the monthly rainfall map.

TMPA (3B42) dataset have been discontinued as of Dec. 31, 2019, and users are strongly encouraged to shift to the successor IMERG dataset (doi: 10.5067/GPM/IMERG/3B-HH/06).
This dataset was the output from the TMPA (TRMM Multi-satellite Precipitation Analysis) Algorithm. It provides precipitation estimates in the TRMM regions that have the (nearly-zero) bias of the âÂÂTRMM Combined Instrumentâ precipitation estimate and the dense sampling of high-quality microwave data with fill-in using microwave-calibrated infrared estimates. The granule temporal coverage is 3 hours.
