The current versions of these products are OSI-402-c for the Sea Ice Edge and OSI-403-c for the Sea Ice Type. On 3 June, they will be replaced with the operational upgraded products, labelled OSI-402-d and OSI-403-d respectively.

Main changes in the upgraded versions are:

  • Sea Ice Type newly introduced for the Southern Hemisphere.
  • Use of Metop-B and C input data instead of Metop-A and B.
  • Change of product format from netCDF3 to netCDF4.
  • Introduction of associated uncertainty fields. The uncertainty field replaces the previous ‘confidence level’ variable which will disappear. The confidence level can be reconstructed from the new uncertainty variable.

More information on the upgraded products can be found on the OSI SAF web pages:
