We are in the process of migrating all NASA Earth science data sites into Earthdata from now until end of 2026. Not all NASA Earth science data and resources will appear here until then. Thank you for your patience as we make this transition.

Precipitation Data Access and Tools
NASA has a wide range of precipitation data, from hourly rainfall estimates to reanalysis datasets looking back decades. Our datasets and tools help users spot characteristics, trends, patterns, and anomalies in the precipitation that falls to Earth and understand how it affects natural areas and human communities.

Featured Precipitation Observation Method: GPM
NASA's Global Precipitation Measurement (GPM) platform provides next-generation global observations of rain and snow to help researchers better understand Earth's water and energy cycles and forecast extreme weather and related events.
During this webinar we will provide an overview of TRMM and GPM precipitation data products and discuss the various ways to discover and access these data. We will also demonstrate the visualization and analysis tools and services provided by NASA's Goddard Earth Science Data and Information Services Center (GES DISC).
NASA’s global precipitation data and data processing systems have come a long way from the launch of TRMM in 1997 to the ongoing GPM mission.
