Snow height on sea ice, meteorological conditions and drift of sea ice from autonomous measurements from buoy 2019S91, deployed during RV Araon 2019 ...
Snow height was measured by the Snow Buoy 2019S91, an autonomous platform, installed on drifting sea ice in the Arctic Ocean during RV Araon 2019. The resulting time series describes the evolution of snow height as a function of place and time between 13 August 2019 and 25 August 2019 in sample inte...
