Description
Summary:EN: This dataset shows the extent of areas with at least 15 percent frequency of sea ice occurrence in April in the Arctic Ocean. The ice frequency, i.e. the percentage of days with observed ice coverage during the given month, has been calculated from 30 years of satellite observations, from 1988 to 2017. The dataset is available in the ESRI shapefile format, as iso lines and polygons.
