Digital Elevation Models from the summer season 2019 at the EastGRIP deep drilling site

DOI

Two-dimensional maps of the snow surface, i.e., digital elevation models (DEMs), were generated from daily sets of photos during the summer season of 2019 at the EastGRIP deep drilling site in the accumulation zone of the Greenland Ice Sheet. From mid-May to the beginning of August 2019, about 170 photos were taken every day along a 40 m long transect using a Sony α 7R camera and a fixed lens of 35 mm focal length. The camera was mounted at a height of ~2 m. The entire covered area is 400 m^2 (= 40 x 10 m). Following a Structure-from-Motion photogrammetry approach described in Zuhr et al. (2021) and using the software Agisoft Metashape, DEMs were generated for each day with suitable weather conditions. The DEMs have a resolution of 1 x 1 cm. Missing areas in the DEMs are either caused by a snow sampling scheme carried out in the same area or by insufficient coverage in the point cloud. The largest gap between consecutive DEMs is three days and happened once. Gaps of two days occurred five times and a one-day gap seven times.
