Data have been extracted from reanalyzed ice and surface temperature maps with a frequency of two datsets (maps) a week. 16 seasons are covered. After 1979 a higher resolution has been created. There will be attempts to combine with this dataset at a later stage. The data file has been read with Matlab and mat files of ice concentration and the icecode. These files are also provided.</abstract><abstract xml:lang="sv">Se den engelska beskrivningen för mer information.</abstract>
