Details/Specifics of Change:

From April 8, 2022 through April 29, 2022, the operational setpoint of GOES-17 ABI will be adjusted to mitigate the impacts of the elevated focal plane module (FPM) temperatures on imagery and maintain the maximum nominal hours of water vapor imagery. See GOES-17 ABI Saturation Prediction Reference Tools for more background information.

The following table summarizes the adjustments to setpoint throughout the April warm period (changes to setpoint are performed at 1500 UTC):

Dates | Setpoint
April 8-10 | 90 K
April 11-18 | 92.8 K
April 19-20 | 90 K
April 21-29 | 87 K

These setpoint changes are independent of the GOES-15 supplemental operations plan scheduled for April 12-18, 2022. These changes are not subject to critical weather day.
