MOSAiC drift expedition from October 2019 to July 2020: sea ice conditions from space and comparison with previous years
We combine satellite data products to provide a first and general overview of the physical sea ice conditions along the drift of the international Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition and a comparison with previous years (2005–2006 to 2018–2019)....
