A preliminary result of the ozone observation at GDR-research base (70.77゜S, 11.85゜E) from May to December 1985

摘要

At 70.77°S, 11.85°E, regular balloon-borne ozone soundings were started in 1985. These soundings have been performed using an electrochemical ozone sonde on the basis of the Brewer principle. A comparison was made with ozone soundings at middle northern latitudes (Lindenberg 52.21°N, 14.12°E). During polar spring, the period of extreme ozone depletion, a double peak structure was typical at 71°S. The analysis of the height variations of two peaks suggests that they are due to different physical mechanisms at high southern and middle northern latitudes.
