Precipitation Measurement Mission Science
NASA’s Precipitation Measurement Missions (PMM) develop and deploy advanced space-borne sensors to gain physical insights into precipitation processes and to enable improved monitoring and forecasting of climate, weather and precipitation-related natural hazards. PMM includes the Tropical Rainfall Measuring Mission (TRMM) and the Global Precipitation Measurement (GPM) mission. TRMM and GPM pursue a unique and innovative approach to measuring precipitation from space through the collection of observations by both active and passive sensors, which are then converted into quantitative precipitation estimates. These datasets are used by scientists for scientific discoveries and by operational agencies in societal applications. The NASA PMM Science Team conducts scientific research on a wide range of areas including precipitation algorithm development, ground validation and integrated science applications.
