The Global Precipitation Measurement (GPM) mission has several cross-cutting application areas which contribute to and enhance our understanding of weather forecasting, disasters, ecology, health, water and agriculture and energy. Using advanced space-borne instruments, GPM measures light rain to heavy rain and falling snow, producing a near-global view of precipitation every 30 minutes. Through improved measurements of rain and snow, precipitation data from the GPM mission is used by a diverse range of applications and user communities at local to global scales to inform decision making and policy that directly benefits society.
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. This section outlines the different types of data available, the levels of processing, the sources to download the data, and some helpful tips for utilizing precipitation data in your research.
