Calibration Coefficients GMS-3
GMS-3: 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)
