Abstract

Tropospheric ozone (O3), ultraviolet B (UVB) radiation and aerosol light scattering coefficients (SC) were investigated on a cruise ship during the fourth Chinese National Arctic Research Expedition from July 1 - September 20, 2010. The results showed that O3, UVB and SC decreased with increasing latitude, with minimum values recorded in the central Arctic Ocean. Average O3 concentrations were 15.9 ppbv and 15.1 ppbv in the Bering Sea and Arctic Ocean, respectively. Ozone concentrations increased to 17.5 ppbv in the high Arctic region. Average UVB values were 0.26 W * m(-2) and 0.14 W * m(-2) in the Bering Sea and Arctic Ocean, respectively. The average SC in the Bering Sea was 4.3 M * m(-1), more than twice the value measured in the Arctic Ocean, which had an average value of 1.7 M * m(-1). Overall, UVB and SC values were stable in the central Arctic Ocean.
