About this dataset

Water is essential for life on Earth, and precipitation is a main source of fresh water for plants and animals. Knowing when, where, and how precipitation falls is critical for science and society. The colored areas on these maps show where and how much precipitation fell around the world on the dates shown and how rain and snow move around the planet. The data are from NASA’s Global Precipitation Measurement (GPM) mission, which provides near-global coverage of precipitation and is updated every half hour. The comprehensive and consistent precipitation measurements from GPM are helping scientists better understand all the elements of Earth’s climate and weather systems along with how these elements are changing.
