Snow height on sea ice, meteorological conditions and drift of sea ice from autonomous measurements from buoy 2019S96, deployed during MOSAiC 2019/20

Snow height was measured by the Snow Buoy 2019S96, an autonomous platform, installed on drifting sea ice in the Arctic Ocean during MOSAiC (Leg 1) 2019/20. The resulting time series describes the evolution of snow height as a function of place and time between 29 Oct 2019 and 01 Aug 2020 in sample i...

Description
Summary:Snow height was measured by the Snow Buoy 2019S96, an autonomous platform, installed on drifting sea ice in the Arctic Ocean during MOSAiC (Leg 1) 2019/20. The resulting time series describes the evolution of snow height as a function of place and time between 29 Oct 2019 and 01 Aug 2020 in sample intervals of 1 hour. The buoy needed re-positioning 2m next to the original position on 14 Jul 2020. The Snow Buoy consists of four independent sonar measurements representing the area (approx. 10 m**2) around the buoy. The buoy was installed on pack ice. In addition to snow height, geographic position (GPS), barometric pressure, air temperature, and ice 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. The data set has been processed, including the removal of obvious inconsistencies (missing values). Records without any snow height may still be used for sea ice drift and meteorological analyses.
