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.
