Topic:
Correction in the NOAA-18 AVHRR Baseplate Temperature Computation
Date/Time Issued:
12 January 2010, 2020 UTC
Product(s) or Data Impacted:
NOAA-18 AVHRR Baseplate Temperature
Date/Time of Initial Impact:
From launch to 5 January 2010
Date/Time of Expected End:
5 January 2010
Length of Event:
From launch to 5 January 2010
Impacts on Users and Significance:
Minor
User Actions:
None
Details/Specifics of Change:
It was identified that NOAA-18 AVHRR had its temperature conversion coefficients for baseplate set incorrectly in the data processing. This error caused the baseplate temperature to be computed incorrectly. The problem was solved. However, the baseplate temperature, which was reported before 5 January 2010 and stored in CLASS and possible other places, was inaccurate.
