Upgrade of OSI SAF the Sea Ice Edge and Type products

As previously announced, the OSI SAF the Sea Ice Edge and Type products are being upgraded. The date for the switch to the new products is set to 03-06-2021, including the products distributed on this day. The upgraded products are labelled OSI-402-d and OSI-403-d. This switch will affect the products distributed both on EUMETCast, FTP and Thredds.

The main changes with respect to the predecessor products (OSI-402-c and OSI-403-c) are the following:

  • Introducing for the first time Sea Ice Type for the Southern Hemisphere
  • ​Using Metop-B and -C, instead of Metop-A og -B.
  • ​Switching from NetCDF3 to NetCDF4 as product format.
  • ​Introducing 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.

The new and old products are available in parallel until 03.06.2021 for users to adapt to the new product on FTP (not on EUMETCast) here:

- old product: ftp://osisaf.met.no/prod/ice/edge and ftp://osisaf.met.no/prod/ice/type
- new product: ftp://osisaf.met.no/prod_test/ice/edge and ftp://osisaf.met.no/prod_test/ice/type
