摘要:

Tropospheric Ozone (O3), Ultraviolet-B radiation (UVB) and Aerosol Light Scattering Coefficient (SC) were investigated along the cruise during the Fourth Chinese National Arctic Research Expedition from July 1st to September 20th in 2010. The results show that O3, UVB and SC display obviously decreasing trend in response to increasing latitude. The minimum values were observed in the central Arctic Ocean. The average concentration of O3 was 15.9 ppbv in the Bering Sea and 15.1 ppbv in the Arctic Ocean, respectively. The concentration of O3 slightly increased to 17.5 ppbv in the high Arctic region. The average value of UVB was 0.26 W/ m2 in the Bering Sea and 0.14 W/m2 in the Arctic Ocean, respectively. The average value of SC in the Bering Sea was 4.3 1/Mm, which was more than two times higher than that in the Arctic Ocean, where the mean value was lower at 1.7 1/Mm. Totally, UVB and SC showed stable in the central Arctic Ocean.
