Aerosol Optical Depth, Ice Cover, and Cloud Cover

Chapter
Part of the SpringerBriefs in Environmental Science book series (BRIEFSENVIRONMENTAL)

Abstract

This chapter investigated the relationships between aerosol optical depth, sea-ice cover (ICE), and cloud cover (CLD) in the Greenland Sea in 20°W–10°E, 65°N–85°N during the period 2003–2012. We focused more on 70°N–80°N and divided it into two 5° zonal apart. Remote sense satellite data were used to do correlation analysis. Enhanced statistics methods are used for correlation and regression analysis. According to the 10-year data, AOD was high in spring, and low in summer, and it rose back again in autumn. AOD content was generally higher in southern region (70°N–75°N) than the northern region (75°N–80°N). AOD and ICE had positive correlations, while AOD and CLD had negative correlations. The peaks of ICE and CLD were all 1 month earlier than the peak of AOD. That indicates both ice cover and cloud cover all had influenced on AOD content. After shifting ICE and CLD 1 month later, they both had long-term equilibrium relationship with AOD. The correlation between AOD and ICE was stronger than the correlation between AOD and CLD, indicating that the aerosols in Arctic mostly came from the sea ice rather than from the air cloud. Melting ice (MI) resulted in the increasing of the AOD content.
