Topic:
AVHRR visible coefficient update for month of August

Date/Time(UTC) Message Issued:
30 July 2003, 1845 UTC

Satellite(s) Involved:
NOAA-16

Instrument(s) Involved:
AVHRR

Product(s) Involved/Affected:
All products using channels 1 and 2

Date/Time(UTC) of Initial Implementation:
12 August 2003, Time TBD UTC

Details/Specifics of Change:
The new calibration coefficients for NOAA-16 AVHRR Channel 1 & 2 for August
2003 are:

Ch_1_lo = .05303*count - 2.044, count<498.96
Ch_1_hi = 0.1549*count - 52.63, count>498.96

Ch_2_lo = .05745*count - 2.176, count<500.16
Ch_2_hi = 0.1691*count - 57.90, count>500.16

where COUNT is raw 10-bit count. These coefficients are expected to be
implemented on August 12 and optimal on August 26, the middle point between
regular updates. The "switch point" will not be changed.
