TRMM Microwave Imager (TMI) Profiling Level 3 Monthly 0.5° x 0.5° V7 (3A12)

Algorithm 3A12, "Monthly TMI Profling", produces global 0.5° x 0.5° monthly gridded means using 2A12 data. Vertical hydrometeor profiles and surface rainfall means are computed. The average operating altitude for TRMM was changed from 350 to 403 km during the period of August 7-24, 2001. This orbit boost maneuver extended the mission life significantly. All post-boost data products had been released by the TRMM Science Project, as of early December 2001. All TRMM data products (post- and pre-boost) are available via the TRMM data search-and-order system at http://mirador.gsfc.nasa.gov/cgi-bin/mirador/presentNavigation.pl?tree=project&project=TRMM . The time period before August 7, 2001 is referred to as pre-boost, and the time period after August 24, 2001 is referred to as post-boost.

If you use the data for your research, please kindly acknowledge the source as follows: "The data used in this study were acquired as part of the Tropical Rainfall Measuring Mission (TRMM). The algorithms were developed by the TRMM Science Team. The data were processed by the TRMM Science Data and Information System (TSDIS) and the TRMM Office; they are archived and distributed by the Goddard Earth Sciences Data and Information Services Center (GES DISC). TRMM is an international project jointly sponsored by the Japan National Space Development Agency (NASDA) and the U.S. National Aeronautics and Space Administration (NASA) Office of Earth Sciences. "

IMPORTANT: After over 17 years of productive data gathering, the instruments on TRMM were turned off on April 8, 2015.
