EOS Senior Project Scientist
The Tropical Rainfall Measuring Mission (TRMM), a joint mission between NASA and JAXA to study rainfall for weather and climate research, was launched in November 1997, with a design lifetime of three years. TRMM officially came to an end on April 8, 2015 (see pmm.nasa.gov/trmm/mission-end); the spacecraft is expected to reenter the Earth’s atmosphere in mid-June. TRMM became a fixture over the global tropics, producing over 17 years of valuable scientific data. TRMM carried five instruments: a three-sensor rainfall suite consisting of the Precipitation Radar (PR), TRMM Microwave Imager (TMI), and Visible and Infrared Scanner (VIRS); and two related instruments, the Lightning Imaging Sensor (LIS) and Clouds and Earth’s Radiant Energy System (CERES). Its unique 17-year dataset of global tropical rainfall and lightning became the space-based standard for...
