TRMM Precipitation Radar Data Suspended

The TRMM satellite is descending, and the users of TRMM Precipitation Radar (PR) data should be aware that the last production orbit of public PR data was orbit #96230 from October 7th, 2014. From that point forward, the TRMM PR data is suspended because no useful cloud data are being observed. It is possible that PR data will again be made available when TRMM descends to the vicinity of its at-launch altitude of 350 km. TRMM Microwave Imager (TMI) data will continue to be produced and publicly available during the descent of the spacecraft until it reaches its decommissioning altitude of 335km.

In lieu of using TRMM PR data, users are encouraged to start using GPM Dual-frequency Precipitation Radar (DPR) data. To view a full table of GPM data products available for download, please visit: http://pmm.nasa.gov/data-access/downloads/gpm
