The Tropical Rainfall Measuring Mission (TRMM) is a joint mission between NASA and the National Space Development Agency (NASDA) of Japan designed to monitor and study tropical rainfall and the associated release of energy that helps to power the global atmospheric circulation shaping both weather and climate around the globe. The TRMM Observatory carries five instruments. It will include the first spaceborne Precipitation Radar (PR), the TRMM Microwave Imager (TMI), a Visible and Infrared Scanner (VIRS), a Cloud and Earth Radiant Energy System (CERES), and a Lightning Imaging Sensor (LIS). TRMM was successfully launched from the Tanegashima Space Center in Japan on November 27, 1997. The TRMM Project Office is responsible for the support of the TRMM mission in connection with ground-based validation of the TRMM observations. The TRMM Office is the focal point for the planning and implementation of a broad and integrated observational program of precipitation and related climate research, designed to meet the specific science validation objectives established by the TRMM science team, and which are also consistent with programmatic requirements established by NASA Headquarters.
