Following #SSMIS impredictable data provision, in order to ensure our users with a reliable service, we are now basing our Sea Ice Index on AMSR-2-based Sea Ice Concentration product.

Release of sea ice index product version v2.3 | OSI SAF

We are now releasing version 2.3 of the OSI SAF Sea Ice Index product. As previously announced (service messages #3328 and #3329), the Sea Ice Index product (OSI-420) will in the future be calculated from the AMSR-2-based Sea Ice Concentration product (OSI-438) instead of the SSMIS-based concentration product (OSI-430-a). Note that sea-ice index values up until July 31, 2025, are identical in versions 2.2 and 2.3. Only index values from August 1, 2025, and onward will be affected by this data input change.
