Summary
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 Random error estimates (mislabeled “relative error” for historical reasons) are provided for each 0.25 x 0.25 degree box. The quality of the 3B42 product is highly sensitive to the quality of the input data: TMI (product 2A12), TRMM Combined Instrument (TCI; product 2B31), and the other input datasets listed in the Summary. If the quality of the input data is less than anticipated, then the quality of 3B42 will also be less. For more, see, ftp://meso-a.gsfc.nasa.gov/pub/trmmdocs/3B42_3B43_doc.pdf
