These maps show the monthly mean sea ice extents. These are defined as the extent of the monthly mean sea ice concentration which exceeds 30% as this limit is used by OSI SAF to distinguish open water and open ice (reference). The maps are additionally overlayed with the corresponding multi-year montly mean percentiles of the period 1979-2021.
