The maps are based on binary maps available in the PANGAEA repository: https://doi.org/10.1594/PANGAEA.986427 (Papin et al., 2025a; Envisat ASAR 2002-2012) https://doi.org/10.1594/PANGAEA.969031 (Swirad et al., 2024; RADARSAT-2 2012-2016), https://doi.org/10.1594/PANGAEA.963167 (Swirad et al., 2023; Sentinel-1A/B 2014-2023), https://doi.org/10.1594/PANGAEA.987853 (Papin et al., 2025b; Sentinel-1A 2023-2025). When two images occurred on the same day, RADARSAT-2 was prioritised over Envisat ASAR and Sentinel-1 because of its lower noise floor. The pixel values of the ice type maps indicate: 0 = open water, 1 = drift ice, 2 = landfast ice, 3 = glacier ice, 7 = uncertain, 8 = masked, 9 = landmask. Note that from 2023-07-01 spatial extent and cell alignment changed.15.91776.983
