  • Snow height was measured by the Snow Buoy 2020S106, an autonomous platform, installed on drifting sea ice in the Arctic Ocean during MOSAiC (Leg 5) 2019/20. The resulting time series describes the evolution of snow height as a function of place and time between 26 August 2020 and 26 June 2021 in sample intervals of 1 hour. The Snow Buoy consists of four independent acoustic range finder measurements representing the area (approx. 10 m**2) around the buoy. In addition to snow height, geographic position (GPS), barometric pressure, air temperature, and surface temperature were measured. Negative values of snow height occur if surface ablation continues into the sea ice. Thus, these measurements describe the position of the sea ice surface relative to the original snow-ice interface. Differences between single sensors indicate small-scale variability of the snow pack around the buoy.
