TRMM Online Visualization and Analysis System (TOVAS)

Important: New Web Host for TOVAS (2013/06/24)
As planned, most TOVAS instances listed below in this page have be converted to the new system and can be accessed through the new TOVAS landing page,

http://disc.sci.gsfc.nasa.gov/precipitation/tovas

Major Changes:

1) The way to obtain a map for precipitation accumulated over a period has been changed in the new TOVAS. To obtain such map, select "accumulated_precipitation" from the parameter list and "Lat-Lon map, Time-accumulated" from "Select Visualization."

2) The "Lat-Lon map, Time accumulated" service is intended only for this parameter, "accumulated precipitation" or the like. Using it for other parameters may not make physical sense.

3) New output formats: HDF, NetCDF, ASCII, and Google Earth KMZ.

This landing page will be re-directed to the above new landing page soon.
