The new OSI SAF North Atlantic Regional Sea Surface Temperature (NAR SST), with product ID OSI-202-c, is an upgrade to the existing OSI SAF NAR SST product with ID OSI-202-b. The main change in OSI-202-c is that SNPP input data have been replaced with NOAA-20 data, resulting in a change in timestamp. The two SNPP files with timestamp 02:00 and 13:00 UTC are replaced by two NOAA-20 files with timestamp 01:00 and 12:00 UTC. There is no change to the two files per day which are based on Metop-B data, with timestamp 10:00 and 20:00 UTC.

OSI-202-c will supersede OSI-202-b on 19 November.

The new OSI-202-c product has been validated against in situ measurements.
