GOES-17 ABI Mode 3 cooling timeline implementation
NOAA will commence operational implementation of the GOES-17 Advanced Baseline Imager (ABI) mode 3 cooling timeline in February 2021, 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 are the four full periods for 2021:
- 6-28 February 2021
- 9 April–1 May 2021
- 11 August–1 September 2021
- 9 October–5 November 2021
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 Level 1B data as follows:
- Full disk 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 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_
Users wishing to receive the Mode 3 15-minute data should contact our User Service Helpdesk.
