TRMM_3B42

TRMM (TMPA) Rainfall Estimate L3 3 hour 0.25 degree x 0.25 degree V7 (TRMM_3B42) at GES DISC

This dataset is the output from the TMPA (TRMM Multi-satellite Precipitation Analysis) Algorithm, and provides precipitation estimates in the TRMM regions that have the (nearly-zero) bias of the ”TRMM Combined Instrument” 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.

Processing Level

Quality 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.
