Details/Specifics of Change:
The following update of the calibration coefficients are
recommended for:
NOAA-18 AVHRR
Ch_1_lo = 0.05279*count - 2.081, count<501.00
Ch_1_hi = 0.1574*count - 54.13, count>501.00
Ch_2_lo = 0.06069*count - 2.391, count<500.00
Ch_2_hi = 0.1821*count - 63.45, count>500.00
NOAA-17 AVHRR
Ch_1_lo = 0.05540*count - 2.217, count<501.12
Ch_1_hi = 0.1627*count - 55.96, count>501.12
Ch_2_lo = 0.06666*count - 2.617, count<500.73
Ch_2_hi = 0.1984*count - 68.70, count>500.73
Ch_3_lo = 0.03218*count - 1.356, count<501.37
Ch_3_hi = 0.2256*count - 98.48, count>501.37
NOAA-16 AVHRR
Ch_1_lo = 0.05500*count - 2.120, count<498.96
Ch_1_hi = 0.1605*count - 54.55, count>498.96
Ch_2_lo = 0.05973*count - 2.256, count<500.16
Ch_2_hi = 0.1760*count - 60.40, count>500.16
on February 13. These coefficients are intended to be optimal on
February 27, in the middle of the two scheduled updates.
