The files based on NPP will be discontinued on 19 November also.
OSI-202-c will become operational and will supersed OSI-202-d on 19 November.

Reminder:
The OSI SAF North Atlantic Regional Sea Surface Temperature (NAR SST), currently based on Metop-B/AVHRR and NPP/VIIRS and identified OSI-202-b will be changed to OSI-202-c. This change corresponds to use of NOAA-20 data instead of NPP data as input.
The 2 files per day based on NPP, dated 02:00 and 13:00, will be replaced by 2 files based on NOAA-20, dated 01:00 and 12:00.
There will be no change on the 2 files per day based on Metop-B and dated 10:00 and 20:00.
