description TRMM Overview
The Tropical Rainfall Measuring Mission (TRMM) was a joint space mission between NASA and the Japan Aerospace Exploration Agency (JAXA) launched in 1997. It was designed to monitor and study tropical and subtropical precipitation using a suite of instruments, including the first spaceborne precipitation radar. Operating in a low-inclination orbit, TRMM provided critical data for understanding the global water cycle, hurricane structures, and climate variability until it was decommissioned in 2015.

help TRMM FAQ
What space agencies built the Tropical Rainfall Measuring Mission (TRMM)?
The TRMM satellite was a joint mission between NASA and the Japan Aerospace Exploration Agency (JAXA). It was specifically designed to measure tropical and subtropical rainfall from space.
When was TRMM decommissioned and how long did it operate?
Originally planned for a three-year mission, TRMM launched in 1997 and operated well beyond its expected lifespan. It was officially decommissioned in 2015 after providing nearly two decades of critical climate data.
What instruments did the TRMM satellite carry?
TRMM carried the first spaceborne Precipitation Radar (PR) designed specifically for measuring rainfall. It also featured the TRMM Microwave Imager (TMI) and the Visible and Infrared Scanner (VIS) to capture comprehensive storm data.
Did TRMM monitor hurricanes?
Yes, TRMM was highly valuable for monitoring tropical cyclones and hurricanes. Its instruments allowed scientists to look inside storms to map the distribution and intensity of precipitation, greatly improving hurricane forecasting models.
