Abstract:
Snow height information derived from digital elevation models (DEMs) from the summer season of 2019 at the EastGRIP deep drilling site (75° 38'N, 36° 00'W, ~2,700 m altitude) in the accumulation zone of the Greenland Ice Sheet. The DEMs cover an area of 400 m^2 (x = 40 m, y = 10 m). A representative area of 20 cm width from y = 1.9 to y = 2.1 m along the 40 m transect was chosen in order to study the snow height evolution throughout the 2019 season (mid-May to the beginning of August). 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. A 20-point moving average is used to provide snow height information for stable water isotope data sampled in the same transect.
