Get the Channel 45 scan head count and convert it to a brightness temperature using UWisc subroutine TEMBCK.F (from Liam Gumley (UWisc)) 2. Call subroutine MASCAL.F (from Liam Gumley (UWisc)) which uses the chan45 scan head temperature and the cold and warm black body counts/temperatures for computing the corrected slope and intercept for all IR bands. Emissivities used were from Liam Gumleys (UWisc) MASCAL.F program BB effective emissivity estimates for all 50 channels (note: set to 1.0 for channels 1-25) For Bands 1 thru 50: 1.0,1.0,1.0,1.0,1.0, 1.0,1.0,1.0,1.0,1.0, 1.0,1.0,1.0,1.0,1.0, 1.0,1.0,1.0,1.0,1.0, 1.0,1.0,1.0,1.0,1.0, 0.98095, 0.98104, 0.98115, 0.98124, 0.98134, 0.98145, 0.98155, 0.98164, 0.98175, 0.98184, 0.98194, 0.98203, 0.98213, 0.98223, 0.98233, 0.98243, 0.94590, 0.94102, 0.93890, 0.93782, 0.93668, 0.93668, 0.93700, 0.93764, 0.93858 ************************* ************************* NOTE: Factor in column 15 is used to scale radiances in calibrated data by the following method: value_stored = int( radiance / factor ) for each channel --- Files and software modified by: Mike Fitzgerald and Jack Penick MAS Level-1B Processing Manager (415) 604-6252 25 December 1996 ***************************************************************
