Elevation change grids of Greenland's periphery for the years 1978, 1981, 1985 and 1987
Abstract
This dataset contains elevation change grids (Digital Elevation Models (DEMs) of Difference) for Greenland's periphery subtracting the AeroDEM (Korsgaard et al., 2016) elevation data from the ArcticDEM (Porter et al., 2023). Four timestamps are available given the four nominal years for AeroDEM acquisition (1978, 1981, 1985, 1987).
The .tif files are the first order filtered DoDs (DEM of Difference) of the entire periphery prior to subsequent empiracle rule filtering and clipping to peripheral ice cap and glacier ablation areas.
