HiSTED_Arctic_SIC_Extreme_Event_Dataset_1991_2020 Wanxia Deng (24844684) Oceanography not elsewhere classified Arctic Sea Ice, Melt Timing, Sea Ice Extent, Sea Ice Area sea-ice concentration satellite remote sensing; extreme-event detection <p dir="ltr">This dataset provides the HiSTED-derived Arctic sea-ice extreme event products for 1991–2020. The dataset was generated from long-term satellite sea-ice concentration records and contains event-level catalogues, event-supported region-day records, date-level records, daily region/date summary tables, detector threshold files, and regional adjacency metadata. The released data support the manuscript “HiSTED: A 3D Spatiotemporal Framework for Detecting Arctic Sea-Ice Extremes from Long-Term Satellite Records”. The source satellite sea-ice concentration data are publicly available from the EUMETSAT Ocean and Sea Ice Satellite Application Facility, and the ERA5 reanalysis variables are publicly available from the Copernicus Climate Data Store.</p> 2026-09-13T08:33:02Z Dataset Dataset 10.6084/m9.figshare.33685003.v1 https://figshare.com/articles/dataset/HiSTED_Arctic_SIC_Extreme_Event_Dataset_1991_2020/33685003 CC BY 4.0
