Global Precipitation Measurement (GPM): Science and Applications


Water is essential to our planet Earth. Knowing when, where and how precipitation falls is crucial for understanding the linkages between the Earth’s water and energy cycles and is extraordinarily important for sustaining life on our planet. The Global Precipitation Measurement (GPM) Core Observatory spacecraft, launched February 27, 2014 in a partnership between NASA and the Japan Aerospace Exploration Agency (JAXA), is the anchor to unify and advance precipitation measurements from a constellation of available research and operational precipitation satellite sensors.

The GPM mission provides essential 2-, 3-, and/or 4-dimensional data at scales from microphysics of rain and snow particles to regional storm events to global patterns of precipitation. The GPM products are important for both scientific investigations and societal applications and allow for detailed investigations of the distribution of precipitation and how patterns change over days, seasons, and years. GPM advances precipitation measurements from space; enhances knowledge of precipitation systems, water cycle variability and freshwater availability; and provides details essential for improving climate, weather, and hydrological modeling and prediction. GPM data are also used to model and estimate hazard impacts (e.g. floods, typhoons, and droughts), weather related disasters, agricultural forecasting, and famine warnings. Read more…
