This data set is the monthly surface rainfall selected from the Tropical Rainfall Measuring Mission (TRMM) Level 3 standard products (monthly and latitude-longitude grid), estimated by the Precipitation Radar (PR), the TRMM Microwave Imager (TMI), the PR and TMI combined algorithm (COMB), and "TRMM and Others Combined" algorithm (TRMM, geosynchronous IR and rain gauges). The data are written in 4-byte real binary (big endian) format.
The browse images and data show the global monthly accumulated rainfall [mm/month]. However, the standard products of PR and
"TRMM and Others Combined" only include the monthly mean rain rate [mm/hour]. Therefore, we also calculate and include the monthly accumulated rainfall of those products in the data set for intercomparison of those rainfall products.
The original TRMM Level 3 standard products, PR Level 3 (3A25), TMI Level 3 (3A12) and COMB Level 3 (3B31), and "TRMM and Others Combined" Level 3(3B43) are processed and supplied by the NASA Goddard Space Flight Center (GSFC) and the JAXA Earth Observation Center (EOC).
