NOAA/NESDIS satellite-derived rainfall rate estimation -- CIMSS modifications

First guess: GOES-8 IR channel 4 cloud top temperature

Correction factor: ETA precipitable water (PW) * relative humidity (RH)

Rainfall rate estimation product

Planned CIMSS modifications:

incorporate hourly GOES sounder PW into correction factor
tune algorithm for 15 minute and rapid-scan image input
collaborate with NOAA/NESDIS on other algorithm enhancements
