Download TRMM and GPM satellite precipitation
Precipitation data from the GPM and TRMM missions are made available free to the public in a variety of formats from several sources at NASA Goddard Space Flight Center.
GPM: The Global Precipitation Measurement mission is an international network of satellites that provide the next-generation global observations of rain and snow to advance our understanding of Earth's water and energy cycle, improve forecasting of extreme events, and provide accurate and timely information to directly benefit society.
TRMM: The Tropical Rainfall Measuring Mission was a research satellite in operation from 1997 to 2015, designed to improve our understanding of the distribution and variability of precipitation within the tropics as part of the water cycle in the current climate system.
By covering the tropical and sub-tropical regions of the Earth, TRMM provided much needed information on rainfall and its associated heat release that helps to power the global atmospheric circulation that shapes both weather and climate (NASA).
