American earth atmosphere satellite. TRMM was an international mission dedicated to measuring tropical and subtropical rainfall. Earth Observing satellite built by NASA Goddard Space Flight Center for NASA, NASDA, Japan. Launched 1997.

AKA: Tropical Rainfall Measuring Mission. Status: Operational 1997. First Launch: 1997-11-27. Last Launch: 1997-11-27. Number: 1 . Gross mass: 3,620 kg (7,980 lb).

TRMM provided long-term data sets of rainfall and energy budget measurements which were to be used to better understand global climate changes and their mechanisms. The spacecraft and four instruments were provided by the USA, while Japan provided one instrument and launch services.

The latent heat released by tropical rainfall played a major role in the global atmospheric circulation and the energy budget. The large spatial and temporal variations in tropical rain made it particularly difficult to measure from the Earth's surface, and TRMM provided measurement accuracies possible only from an orbiting platform.

The spacecraft was 3-axis stabilized, with zero momentum bias. Two solar panels provided 1100 W. Data downlink was via TDRSS.

The payload consisted of:

Project total cost was $ 650 million.
