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.
