TRMM/TMPA and Other Sources Monthly Rainfall Product (TRMM Product 3B43 v7)

[ Get Data ]

Abstract: The Tropical Rainfall Measuring Mission (TRMM) is a joint U.S.-Japan satellite mission to monitor tropical and subtropical precipitation and to estimate its associated latent heating. TRMM was successfully launched on November 27, at 4:27 PM (EST) from the Tanegashima Space Center in Japan.

The rainfall measuring instruments on the TRMM satellite include the Precipitation Radar (PR), an ... View entire text

Quality Satellite/gauge relative error estimates are provided for each 0.25 x 0.25 degree box. The estimates are derived in two steps: (1) the error estimates of each input data are computed separately, mostly reflecting the sampling-induced uncertainty of each field and (2) a linear combination of these field errors is computed, in which each field error estimate is weighted by the inverse of its ...
