NASA’s Global Precipitation Measurement Mission (GPM) uses satellites to measure Earth's rain and snowfall for the benefit of mankind. Launched by NASA and JAXA on Feb. 27th, 2014, GPM is an international mission that sets the standard for spaceborne precipitation measurements. Using a network of satellites united by the GPM Core Observatory, GPM expands on the legacy of the Tropical Rainfall Measuring Mission (TRMM) by providing high quality estimates of Earth’s rain and snowfall every 30 minutes.

Latest Half-hour of Earth's Precipitation
The Integrated Multi-satellitE Retrievals for GPM product combines precipitation observations using infrared and microwave sensors from a constellation of partner satellites, united by the GPM Core Observatory, to provide near real-time half-hourly precipitation estimates at 10km resolution for the entire globe.
NASA scientists are building a catalog of landslides so we can be prepared when the next natural disaster strikes. Join our citizen science project to help track landslides and improve prediction models.
The NASA Earth Applied Science Disasters Program promotes the use of Earth observations to improve prediction of, preparation for, response to, and recovery from natural and technological disasters.
An international citizen science initiative to understand our global environment. Your observations help scientists track changes in clouds, water, plants, and other life in support of climate research.
