NSS.LHRR.NL.D04041.S1708.E1719.B1745555.WI
The calibration coefficients for NOAA-16 AVHRR Channel 1 & 2 were updated
to:
Ch_1_lo = .05334*count - 2.057, count<498.96
Ch_1_hi = 0.1557*count - 52.92, count>498.96
Ch_2_lo = .05798*count - 2.190, count<500.16
Ch_2_hi = 0.1708*count - 58.63, count>500.16
on February 10, which will be optimal on February 24, in the middle of the
two planned updates.
