Short summary
Greenland Terminus Position Dataset (GrTPD) is a new manually delineated dataset of glacier terminus positions for the Greenland Ice Sheet, providing spatially extensive and seasonally targeted coverage across marine-, land-, and lake-terminating glaciers. The dataset includes 19 171 terminus delineations for 465 glaciers spanning 2002–2021, derived from multi-source optical and SAR satellite imagery using standardized workflows.
