Several TRMM data products have been added to the new TOVAS instances as part of the transitional phase between the predecessor TOVAS and the current Giovanni system. The data products can be found at the links below to these TOVAS Giovanni instances:
3-hourly TRMM and Other Rainfall Estimate (3B42 V6)
TRMM Level-3 Monthly Products (3B43_V6, 3A12_V6, and 3A25_V6)
In the new instances, additional visualization options and data dowload options (HDF, netCDF, ASCII) and image download options (KMZ for Google Earth) are available.
