Abstract:
This dataset provides record of glacier surface melt conditions on Devon Ice Cap, Nunavut, Canada, derived from sub-weekly Sentinel-1 synthetic aperture radar (SAR) Extra Wide (EW) mode imagery and digital elevation model (DEM) derivatives for the period 2015–2024. A convolutional neural network (CNN) was trained using 8,297 manually labelled samples to classify four surface classes: glacier ice, slush, wet snow/firn, and dry snow. The repository includes ~300 classified raster products for each acquisition period. All data are georeferenced, time-stamped, and formatted for direct integration into GIS and remote sensing workflows.
This dataset can be used for melt onset, extent, and duration across a decade of observations and supports applications in surface mass balance assessment, firn evolution studies, and the development and benchmarking of machine learning approaches for SAR-based cryospheric monitoring in the Canadian Arctic Archipelago.
