Snow height information derived from Digital Elevation Models from the summer season 2019 at the EastGRIP deep drilling site

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 repr...

Description
Summary: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.
