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.
