Time Series Analysis of Arctic New Ice Extent by Using Multi-source Remotely Sensed Data

Sea ice is the most active and unstable component in polar region that its change is significant for the investigation of regional and global climate and environmental change. In this research, the Arctic sea ice and new ice extent from 2004 to 2012 were extracted and their time series changes were analyzed by using multi-source remotely sensed data. The results indicate: there was an inverse relationship between the sea ice extent changes and the near surface air temperature variations;the new ice extent changes were inversely proportional to the sea ice extent changes;the regional new ice extent changes and the near surface air temperature variations had a close relationship.
