warn_icon.gif IMPORTANT MESSAGE Aug 12, 2014    [realtime] TRMM power saving and its possible impact on data distribution    

TRMM realtime users,

 For those who use TRMM PR and LIS, there will be a disruption in data availability. Cell shorts in one of TRMM's batteries necessitates that we shed significant power load right away. As a result, PR and LIS will be temporarily turned off.  We expect the instruments to return to normal observations on Thursday.  This could be the first of many times that this occurs as TRMM's batteries show their age (almost 17 years now).  Also, as TRMM continues to descend, we expect PR data to stop (around November) as TRMM drops below PR's normal operational window.  PR data would become available for a few months (estimated to be in late 2015) when TRMM falls through its original operational altitude of 350 km, assuming that the batteries are healthy enough.

Currently TMI data is not affected.

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.

PDISC Guide for New Users

For users new to the PDISC, we offer a getting started guide.

Precipitation Data Services at the DISC

  • Facilitate data access, information processing to support precipitation research and decision making
  • Nurture cross disciplinary precipitation related research, such as energy and water cycle, aerosol-precipitation interactions

The data holdings at the PDISC consist of remote sensing, in-situ and forecast (to be added in the future) precipitation and ancillary data. The PDISC also provides access to near-real-time and historical precipitation data. The TRMM Online Visualization and Analysis System TOVAS provides a fast and easy way to access the most popular products. While you're here, check out:
