Among the many data types available from NASA's Goddard Earth Sciences Data and Information Services Center (GES DISC), precipitation data is both one of the most recognizable and most scientifically useful. GES DISC features data generated by two missions: the Tropical Rainfall Measuring Mission (TRMM), which collected data from 1997 to 2015, and the Global Precipitation Measurement (GPM) mission, which began collecting data in 2014 and is continuing at present. GES DISC provides multiple ways for users to acquire data from these missions, several different Web services that enable visualization and initial analyses.

This presentation will describe and distinguish precipitation data products available from TRMM and GPM, delineate the different ways that users can get the data, and also demonstrate the visualization and analysis tools and services provided by GES DISC for these important data sets. Examples of recent noteworthy precipitation events will be used as exemplars for meteorology and climate research. For more information visit GES DISC.
