Abstract

Surface ozone measurements were carried out at Molodezhnaya (67.40°S, 45.50°E) and Mirny (66.33°S, 93.01°E) stations in spring 1987-autumn 1988 with a Dasibi 1008-AH ozone analyzer. The data show an annual variation with a summer minimum at 15 ppbv value. The striking feature of the surface ozone record is two types of day-to-day variability. One of the types is characterized by large day-to-day variations with about 10 ppbv magnitude. The likely mechanism of such variations is the vertical transport induced by cyclonic activity. The other type occurs in synoptically quiet periods (frequent in summer) when the day-to-day ozone variations are significant but not so large. The most likely mechanism of these variations is the slope katabatic wind which transports ozone from inside the Antarctic continent. The latitudinal distribution of surface ozone for this period, measured aboard an aircraft, showed a slight increase towards Vostok (78.28°S, 106.48°E) station.
