Topic: GOES-18 ABI desert monitoring calibration scan

Date/Time Issued: October 6, 2022 1833Z

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

Date/Time of Initial Impact: October 14, 2022

Date/Time of Expected End: November 14, 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 October 14 and November 14, ABI Desert Monitoring PLT activities for GOES-18 will be ongoing. A desert monitoring calibration scan will be performed at a 6 day cadence from October 14 to November 7 and a 7 day cadence from November 7 to November 14 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 desert monitoring calibration schedule is as follows for the interleave period:

Date | DOY
14-Oct-22 | 287
20-Oct-22 | 293
26-Oct-22 | 299
1-Nov-22 | 305
7-Nov-22 | 311
