Calibration Coefficients GMS-2
GMS-2: Normalized coefficients for VIS scaled radiances (0 to 1) and IR brightness temperatures in Kelvins. The Normalized coefficients result from comparison to the reference AVHRR for that time period. (NOAA-7: July 1983 - January 1985, NOAA-9: February 1985 - October 1988, NOAA-11: November 1988 - August 1994, NOAA-14: January 1995 - September 2001, NOAA-16: October 2001 - December 2005, NOAA-18: January 2006 - present)

GMS-2: Absolute coefficients for VIS scaled radiances (0 to 1) and IR brightness temperatures in Kelvins. The Absolute coefficients combine all ISCCP calibration adjustments, including the aircraft calibration, to produce the final Absolute tables in the BT dataset.
