The Satellite Analysis Branch (SAB) of NOAA's
National Environmental Satellite, Data, and Information Service
produces an experimental graphical representation of the forecast Tropical Rainfall Potential (TRaP) for any tropical system in the
Western Hemisphere and many in the Eastern Hemisphere. This is an objective analysis done by taking the latest microwave Rain Rate
data from the Defense Meteorological Satellite Program's Special Sensor Microwave Imager (SSM/I), the NOAA-15 Advanced Microwave
Sounder Unit (AMSU), or the NASA Tropical Rainfall Measuring Mission (TRMM) and performing an extrapolation of the rain rate values
based on the latest forecast track and speed. Official forecast bulletins issued by the NOAA
National Hurricane Center and
Central Pacific Hurricane Center for the Western Hemisphere and the
Joint Typhoon Warning Center (JTWC) for the Eastern Hemisphere are used in performing
the extrapolations. This can be done for Tropical Depressions, Storms, and Hurricanes/Typhoones/Cyclones.
