The following update of the calibration coefficients have been implemented:
*NOAA-16 AVHRR
Ch_1_lo = 0.05418*count - 2.089, count<498.96
Ch_1_hi = 0.1581*count - 53.75, count>498.96
Ch_2_lo = 0.05835*count - 2.204, count<500.16
Ch_2_hi = 0.1719*count - 59.00, count>500.16
NOAA-17 AVHRR
Ch_1_lo = 0.05494*count - 2.199, count<501.12
Ch_1_hi = 0.1613*count - 55.50, count>501.12
Ch_2_lo = 0.06649*count - 2.611, count<500.73
Ch_2_hi = 0.1979*count - 68.53, count>500.73
Ch_3_lo = 0.03181*count - 1.341, count<501.37
Ch_3_hi = 0.2230*count - 97.35, count>501.37
NOAA-18 AVHRR
Ch_1_lo = 0.05346*count - 2.108, count<500.54
Ch_1_hi = 0.1594*count - 54.82, count>500.54
Ch_2_lo = 0.06140*count - 2.419, count<500.40
Ch_2_hi = 0.1842*count - 64.19, count>500.40
on January 10. These coefficients are intended to be optimal on January 27, in the middle of the two scheduled updates.
