This dataset contains one snow covered digital elevation model (DEM) and one snow depth product from April 10, 2019 over the Trail Valley Creek research watershed, Northwest Territories, Canada (68°44'25 N, 133°29'36 W). The products are derived from airborne laser scanner data that was collected with a Riegl VQ-580 on board the Alfred Wegener Institute's POLAR-6 science aircraft. The snow covered DEM contains the snow covered landscape elevations, i.e. the terrain and the snow. To obtain snow depth, a snow-free digital terrain model (DTM) needs to be subtracted from the snow covered DEM. We also provide a snow depth product, which we obtained by subtracting snow-free DTMs of Trail Valley Creek and the Inuvik to Tuktoyaktuk Highway (ITH) (both from August 2018) from the DEM including snow cover. Please note that the snow depth product covers only parts of the complete snow covered DEM. The data can be used for analysing spatial snow accumulation patterns. ...
