Topic: GOES-18 ABI Desert Monitoring Calibration Scan

Date/Time Issued: July 28, 2022 1510Z

Product(s) or Data Impacted: GOES-18 ABI outage and mode change

Date/Time of Initial Impact: August 3, 2022

Date/Time of Expected End: September 6, 2022

Length of Outage: Approximate 5 minute outage followed by 5 minutes of Continuous Full Disk mode

Details/Specifics of Change:

During the first period of GOES-18 and GOES-17 interleave between August 1st and September 6th, ABI Desert Monitoring PLT activities for GOES-18 will be ongoing. A desert monitoring calibration scan will be performed at a 3 day cadence from Aug 3rd to Aug 9th and a 4 day cadence from August 9th to September 6th to correspond to the Solar calibration schedule during this time.

The GOES-18 ABI Desert Monitoring Calibration scan will interrupt one 10 minute Flex Mode (Mode 6) timeline between 1900 and 2000 UTC, resulting in a 5 minute outage followed by a 5 minute Continuous Full Disk (Mode 4).

A GOES-18 ABI routine desert monitoring calibration scan will occur on the listed days during interleave following the schedule below:
