NASA | TRMM at 15: The Reign of Rain

The TRMM satellite, launched in 1997, was initially a five-year mission but has provided valuable data for over 15 years. It has advanced research in agriculture, disease tracking, and natural hazards by offering high-resolution rainfall estimates. TRMM's data has enhanced understanding of weather patterns, including El Nino and hurricanes. Its unique instruments, like the precipitation radar and microwave imager, have provided detailed storm analyses. The upcoming GPM mission will build on TRMM's success, offering more advanced instruments and broader coverage.

What are the key instruments used by Trim, and how do they function?
