Precipitation Measurement Missions (PMM)

NASA’s Precipitation Measurement Missions – TRMM (1997–2015) and GPM Core Observatory (2014–present) – provide advanced information on rain and snow characteristics and detailed three-dimensional knowledge of precipitation structure within the atmosphere, which help scientists study and understand Earth's water cycle, weather and climate.
