Topic:
NOAA-19 AVHRR channel-2 calibration coefficients update

Date/Time (UTC) Message Issued:
3 May 2010, 1735 UTC

Satellite(s) Involved:
NOAA-19

Instrument(s) Involved:
AVHRR

Product(s) Involved/Affected:
All products involving channel 2.

Date/Time(UTC) of Initial Implementation:
3 May 2010, Time 1500 UTC

Details/Specifics of Change:
On 3 May 2010 at approximately 1500 UTC, the operational NOAA-19 AVHRR channel-2 calibration coefficients were replaced with those adopted for March 2010 for better calibration. After the replacement, the calibration coefficients for NOAA-19 AVHRR channel 2 are

Ch_2_lo = 0.05465*count - 2.119, count<500.37
Ch_2_hi = 0.16277*count - 56.19, count>500.37

Consequently, the first orbits processed were
