Topic: GOES-18 ABI solar calibration scans
Date/Time Issued: July 28, 2022 1305Z
Product(s) or Data Impacted: GOES-18 ABI product outages
Date/Time of Initial Impact: Aug 3rd, 2022 1510-1520 UTC
Date/Time of Expected End: Sept 6th, 2022 1510-1520 UTC
Length of Outage: Approximately 5 minutes during a period of Continuous Full Disk operations
Details/Specifics of Change:
During the first period of GOES-18 and GOES-17 interleave between August 1st and September 6th, ABI Solar Calibration PLT activities for GOES-18 will be ongoing. Solar calibrations 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.
GOES-18 ABI 10-minute Flex Mode (mode 6) will be replaced with 10 minutes of Continuous Full Disk (mode 4) from approximately 1510-1520 UTC +/- one 10 minute ABI mode 6 timeline. A GOES-18 ABI solar calibration scan will be performed during one of the two scheduled 5 minute Continuous Full Disk (Mode 4) timelines, resulting in an outage of all ABI products. ABI 10-minutes Flex Mode (mode 6) will resume at approximately 1520 UTC +/- one 10 minute ABI mode 6 timeline. The next Full Disk scan will populate at 1520 UTC +/- one 10 minute ABI mode 6 timeline.
The GOES-18 Solar Calibration schedule is as follows for the interleave period:
