Observation and Analysis of Vertical Ozone Variation over the Arctic Chukchi Sea
北极楚克奇海上空臭氧垂直变化的探测与分析

Chinese first scientific research expedition was carried out in the summer of 1999. Analysis on the observation data, TOMS total ozone, and NCEP circulation shows a close relationship between total ozone and ozone below 13 km over the Chukchi Sea, while the variation in the maximum concentration at about 20 km does not show any relation to the TOMS total ozone. Results show that the total ozone variation is mainly dependent on the lower ozone variation. The atmospheric ozone amount experienced a high-low-high variation, with low-high-low tropopause altitude in the observation. The synoptic system in 500 hPa maybe responsible to the local ozone variation.
