Quicklooks at TRMM Orbits

Displays of realtime data on this site may be intermittent today due to server maintenance.

"Quicklook" images are made from TRMM Microwave Imager (TMI) data. Microwave brightness temperatures at 85.5 GHZ and at 37.0 GHZ are combined in the red, green and blue components (guns) of the images. This provides us with an overview of the material covering parts of the Earth over time.

Learn more about the TMI instrument.

June 16, 2015 Update: The TRMM instruments were turned off on April 8, 2015 and the spacecraft re-entered the Earth’s atmosphere on June 15, 2015, at 11:55 p.m. EDT, over the South Indian Ocean. This page remains for archival purposes.
