Supraglacial lake winter drainages in Northeast Greenland (2014/15–2023/24) from C-band SAR

This dataset provides GeoPackage vector layers of supraglacial lake polygons and winter drainage events across Northeast Greenland for the 2014/15–2023/24 winter seasons, derived from C-band SAR observations. The archive includes (i) a 10-year melt-season lake mask with unique lake identifiers and associated basin and elevation attributes, and (ii) annual GeoPackages of drained-lake polygons with drainage timing, lake identifiers, basin, elevation, and estimated volume (km³) and mean depth (m).
