The Precipitation Measurement Missions (PMM) use advanced space-borne instruments to measure global precipitation. Through improved measurements of rain and snow, precipitation data from the Tropical Rainfall Measuring Mission (TRMM) and the Global Precipitation Measurement (GPM) mission reveals new information on hurricane eyewalls and intensity, measures hazard-triggering rainfall events, provides input into climate and land surface models, and offers new insights into agricultural productivity and world health. PMM’s remotely sensed precipitation data enable a diverse range of applications across agencies, research institutions and the global community.
