Sensor weighted solar spectral irradiance (Watts/meter2/micron) at mean Earth-Sun distance --- NOTE: Calibration technique was taken from : MODIS Airborne Simulator VIS and NIR Version 1.0 Calibration WAL-Aug97 Field Experiment by Mike Fitzgerald (NASA/Ames) 6 Oct. 1997 --- Conversion from counts to radiance in VIS and NIR channels is Note: there was no instrument temperature correction performed! rad = (count - (cbb_avg)) * slope where, rad = radiance cbb_avg = cold black body counts (running average) slope = from column 7 in above table count = count value *********************************** IR Emissivity Correction (for MAS-50) From Chris Moeller (UWisc) *********************************** This is done in 2 steps: 1. 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 ***************************************************************
