Snow height on sea ice and sea ice drift from autonomous measurements from buoy 2022S117, deployed during Charcot expedition 2022 ...

Snow height was measured by the Snow Buoy 2022S117, an autonomous platform, drifting on Arctic sea ice, deployed during the expedition with Le Commandant Charcot in 2022. The resulting time series describes the evolution of snow height as a function of place and time between 12 Aug 2022 and 06 Feb 2...

Description
Summary:Snow height was measured by the Snow Buoy 2022S117, an autonomous platform, drifting on Arctic sea ice, deployed during the expedition with Le Commandant Charcot in 2022. The resulting time series describes the evolution of snow height as a function of place and time between 12 Aug 2022 and 06 Feb 2023 in sample intervals of 1 hour. The Snow Buoy consists of four independent sonar measurements representing the area (approx. 10 m**2) around the buoy. The buoy was installed close to the North Pole. In addition to snow depth, geographic position (GPS), barometric pressure, air temperature, and an internal ice 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 and contains quality flags for different kinds ...
