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:

Details/Specifics of Change:
The September CPIDS update of the AVHRR Visible Calibration Coefficients was
performed at 12:30 Local today September 09,2003.
The first orbits processed after the update are:
NSS.LHRR.NL.D03252.S1355.E1403.B1528080.GC
NSS.GHRR.NL.D03252.S1447.E1633.B1528182.GC
NSS.HRPT.NL.D03252.S1758.E1813.B1528383.WI
The new calibration coefficients for NOAA-16 AVHRR Channel 1 and 2 for
September 2003 are;
Ch_1_lo = .05309*count -2.047, count<498.96
Ch_1_hi = 0.1550*count -52.67, count>498.96
Ch_2_lo = .05750*count - 2.172, count<500.16
Ch_2_hi = 0.1694*count - 58.15, count>500.16
where COUNT is raw 10-bit count. These coefficients are expected to be
optimal on September 27, the middle point between the scheduled updates on
September 9 and October 14.
