TRMM Online Visualization and Analysis System (TOVAS)

TRMM Level-3 Monthly Products.


Home
This web based tool is designed for visualization and analysis of the TRMM Level-3 data products. Users can generate plots for Lat-Lon Map, Time Series, Hovmoller diagram and more. Animation is available for Lat-Lon Maps. Results can be downloaded in HDF, NetCDF, ASCII, and Google Earth KMZ formats. Further information is available: 3B43, 3A12, 3A25.

Note: 1) NO swath based latent heating (LH) should be used as is and this includes the roll up in 3A12. Please use the radar or combined LH products.
          2) The "Lat-Lon map, Time accumulated" service is intended only for this parameter, "Accumulated Rainfall." Using it for other parameters will not make physical sense.

Select:
Vertical Profile
Select a vertical profile range. The range selection is disabled unless a qualifying parameter is selected. In order to enable this option (and populate the list with values), select a 3D parameter. 3D parameters have at least three dimensions and are labeled with a '(3D)' in the 'Parameters' section.
NOTE:  Selected 3D parameters must have the same 3rd dimension (e.g., pressure, altitude, wavelength, etc.) units in order to enable the vertical level menu.
