The CALFIN Subseasonal Greenland Glacial Terminus Positions, Version 1 data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set contains polyline and polygon shapefiles of glacial terminus positions in Greenland from 1972 to 2019. The temporal resolution is sub seasonal and the spatial resolution is approximately 30m. Shapefiles are available for individual glaciers and there are also shapefiles that contain all of the glaciers that were studied. The vector data were created from Landsat 1-8 satellite imagery using the Calving Front Machine Neural Network (CALFIN).
