New OSI SAF Northern High Latitude Sea and Sea Ice Surface Temperature products

Two updates to the family of OSI SAF High Latitude SST/IST products are introduced:

  1. L2 products — a dedicated SNPP VIIRS Northern High Latitude product is being introduced. This product is labelled OSI-205-b, and comes in addition to the existing OSI-205-a, based on Metop-B AVHRR data. OSI-205-b is produced for each orbit of SNPP VIIRS data provided through the EARS regional service.
  2. L3 products — two new 12-hourly 5km gridded products are being introduced:
    a. OSI-203-a, based on the Metop-B AVHRR L2 SST/IST product (OSI-205-a)
    b. OSI-203-b, based on the SNPP VIIRS L2 SST/IST product (OSI-205-b)
    These two L3 products will replace the current multi-sensor product (OSI-203), which will be discontinued on 10 September 2019.

All the new products are in GHRSST compliant netCDF4 format and cover the High Latitudes seas and ice areas north of 50N. The existing OSI-205-a is poleward of 50N and 50S.

As the OSI-203 will be discontinued in September, users are encouraged to start using the OSI-203-a and OSI-203-b products instead.
