Abstract

Abstract:

As an important component of the global climate, Arctic sea ice is considered as an indicator of climate change. The study on the temporal change in the Arctic sea ice has the valuable theoretical importance for the global climate system as well as the practical significance in opening new shipping channels. In this study, we use 10 years' AMSR-E L2 products, which include the daily ice concentration of the Arctic sea, to calculate the monthly ice concentration, and then we analyze the change trajectories of ice concentration. The results show that the ice density in Arctic sea considerably decreased in these years. Generally, the Arctic ice cover reaches its peak in January and reaches its lowest record in September. Because of the rapid decline of sea ice, the ice between the Arctic and lands begins to vanish for few months in a year, which increases the likelihood of activities at Arctic sea, for example, opening up a new channel.
