ERAD 2006 Proceedings of Remaining Challenges in Satellite Precipitation Estimation Using the Tropical Rainfall Measuring Mission

Launched in 1997, the Tropical Rainfall Measuring Mission (TRMM) satellite is a joint effort of NASA and the Japanese Space Agency to improve the estimation and characterization of tropical rainfall. The TRMM satellite carries two instruments for measuring precipitation: a multifrequency passive microwave radiometer (TRMM Microwave Imager – TMI) and a 13.8 GHz frequency precipitation radar (PR) (Kummerow et al. 1998). These instruments on the TRMM satellite allow for both simultaneous and independent measurement of storm characteristics between 35o N and 35o S latitude.
