Abstract: The purpose of the TRMM Ground Validation (GV) program is to develop validation methods and to obtain reliable surface-based data during the TRMM mission, with which the TRMM satellite measurements can be verified.
... The TRMM GV network consists of four primary or direct data (DD) sites and seven direct product (DP) sites. The four DD sites are Darwin, Australia; Melbourne, Florida; Houston Texas; and Kwajalein. The seven DP sites are located in Taiwan, Israel, Thailand, Brazil, Guam, and special climatology-multiple radar sites in Florida and Texas.
TRMM GV product 3A54 consists of a Monthly 2 km Ground Radar Site Rain Map of the Surface rain total from ground radar.
Information and data access for all of the Goddard DAAC's hydrology data holdings, including TRMM data from the TMI, Precipitation Radar (PR) and Visible and Infrared Scanner (VIRS) instruments, the Ground Validation (GV) radar data, and ancillary and correlative data products.
