FUNCTION kaufcals(hostbl, satnum, ayear, aday, Kval, ocoeffs)
char *hostbl; long satnum; long ayear; long aday; float Kval[]; long ocoeffs[];
The host file name of the calibration degradation table.
The number of the satellite acquiring the pass (for example, 11 for NOAA-11).
The acquisition year of the pass (ie. 94 for 1994).
The acquisition julian day of the pass.
The K value for AVHRR channels 1 and 2 of this satellite. These values are used to convert radiance to albedo.
The calibration coefficients of the AVHRR visual channels (channels 1 and 2).
kaufcals() returns calibration coefficients for AVHRR channels 1 and 2 based on Kaufman & Holbens values which use a linear degradation over time. If the satellite is NOAA-06, return prelaunch calibration values (since NOAA-06 maintained nearly constant calibration over its lifespan). For all other satellites, calculate visual coefficients using a degradation table.
