Global Precipitation Measurement - NASA

The Global Precipitation Measurement (GPM) mission is an international network of satellites that provide the next-generation global observations of rain and snow..

GPM provides global precipitation measurements with improved accuracy, coverage and dynamic range for studying precipitation characteristics. GPM is also expected to improve weather and precipitation forecasts through assimilation of instantaneous precipitation information.

Improved knowledge of the Earth’s water cycle and its link to climate change

New insights into storm structures and large-scale atmospheric processes

New insights into precipitation microphysics

Advanced understanding of climate sensitivity and feedback processes

Extended capabilities in monitoring and predicting hurricanes and other extreme weather events

Improved forecasting abilities for natural hazards, including floods, droughts and landslides.

Enhanced numerical prediction skills

Improved agricultural crop forecasting and monitoring of freshwater resources

Spatial Resolution 0.1 degrees and 5 km.
