Comparison of Leads Mapping in the Arctic Ocean Between Landsat and MODIS Ice Surface Temperature Products

The sea ice concentration product derived from the Microwave Radiation Image sensors on board the FengYun-3 satellites can reasonably and independently identify the seasonal and long-term changes of sea ice, as well as extreme cases of annual maximum and minimum sea ice extent in polar regions. It is comparable with other sea ice concentration products and applied to the studies of climate and marine environment.

Atmospheric circulation anomalies lead to high Arctic sea ice outflow in winter 2020, causing heavy ice conditions in Barents-Greenland Seas, subsequently leading to ocean warming and inhibited phytoplankton blooms. This suggests that the winter–spring Arctic sea ice outflow can be considered as a predictor of changes in sea ice and other marine environmental environments in the Barents-Greenland Seas, which could help to improve the understanding of the physical connections between them.
