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.
