NOAA will continue the operational implementation of the GOES-17 Advanced Baseline Imager (ABI) mode 3 cooling timeline in February 2022, affecting the ABI data distributed on EUMETCast.

This is to mitigate the number of saturated images resulting from the loop heat pipe (LHP) temperature regulation anomaly.

This cooling timeline will occur seasonally in operations for four periods each year. Below is the next period for 2022:

  • 14 October–15 November 2022

During these periods, every day between 06:00 and 12:00 UTC, GOES-17 operations mode will change from Mode 6 to Mode 3. This will affect the EUMETCast distribution of ABI data as follows:

  • Full disc scans will be available every 15 minutes during the Mode 3 operations (instead of every 10 minutes for the Mode 6 operations).
  • The change to Mode 3 also means that there will be a temporary filename change of GOES-17 ABI data:
    • For Level 1B data, filenames will start with ‘OR_ABI-L1b-RadF-M3C<channel number>_G17_’ instead of ‘OR_ABI-L1b-RadF-M6<channel number>_G17_’
    • For Level 2 products (All-Sky Radiance and Clear-Sky Radiance), ‘M6’ in the filenames will become ‘M3’:
      All-Sky Radiance (ASR): ABI-L2-ASRF-M3_v2r1_g17_s202202260600359_e202202260611126_c202202260623060.bufr
      Clear-Sky Radiance (CSR): ABI-L2-CSRF-M3_v2r1_g17_s202202260600359_e202202260611126_c202202260623050.bufr

GOES-17 L2 products (ASR/CSR) are expected to be missing throughout the cooling timeline periods.
