Lead fractions from SAR-derived sea ice divergence during MOSAiC

Leads (openings in sea ice cover) are created by sea ice dynamics. Because they are important for many processes in the Arctic winter climate, we aim to detect them with satellites. We present two new techniques to detect leads width of a few hundred meters at a high spatial resolution (700 m) and i...

Description
Summary:Leads (openings in sea ice cover) are created by sea ice dynamics. Because they are important for many processes in the Arctic winter climate, we aim to detect them with satellites. We present two new techniques to detect leads width of a few hundred meters at a high spatial resolution (700 m) and independent of clouds or sun illumination. We use the MOSAiC drift 2019/2020 in the Arctic for our case study and compare our new products to 6 existing lead products.
