Abstract

Aircraft measurements of the tropospheric O ₃ concentration were made over Syowa Station, Antarctica from May 1989 to January 1990, except during the polar night months of June and July. The O ₃ concentration increased with height for the whole period of the measurements. Lower tropospheric O ₃ concentration showed a prominent seasonal variation with maximum concentration in winter and minimum in summer, which is very close to the result of continuous O ₃ measurements at Syowa Station. In the upper troposphere, the concentration reached high values in winter, decreased gradually from September to early November and then increased again. As a result, the height-dependent difference of the concentration was reduced from late fall to early spring and enhanced in the remaining seasons of the year. From these results, it is hypothesized that the seasonal variation of height-dependent atmospheric transport processes could influence that of the tropospheric O ₃ concentration over Syowa Station.
