Precipitation: OVERVIEW

warn_icon.gif IMPORTANT MESSAGE Jul 24, 2015    Why do my Data Holdings look different?    

Accessing your data through the GES DISC web site may seem a little unfamiliar to you to these days, but we can assure you, your data is all still available. The location of the data in the online archive has not changed.

The GES DISC has implemented a new interactive interface to make finding data easier than ever. We've added features like searching by keywords, filtering by criteria such as measurements, processing level and spatial resolution, and sortable data columns so now you can fine tune your search results. To get you started we put together a Help document to introduce you to the new interface. If you have any questions about the new design please contact us using the Feedback link in the upper right-hand corner or contact the GES DISC Help Desk by sending email to

Welcome to the Precipitation Data and Information Services Center (PDISC). Here are some links to help you get started:

Global Precipitation Measurement (GPM)

GPM LogoAn international satellite mission to be launched by NASA and JAXA in 2014 that will set new standards for precipitation measurements worldwide using a network of satellites united by the GPM Core Observatory.  For more information on the mission visit the Precipitation Measurement Missions informational web site.

The GES DISC will archive the data and provide the same expansive services currently offered to the user community for the TRMM data products. More information will be available as the data gets closer to the launch of the mission.


Search for Precipitation Data
