A Special Ozone Observation at Syowa Station, Antarctica from February 1982 to January 1983

Abstract

The Atmospheric ozone plays a significant role in heat balance of the stratosphere. Its behavior at high latitude is of special interest, since the stratospheric ozone at high latitude is thought to be transported from lower latitude through dynamical processes. However limited information is so far obtained, because the ozone observation at high latitude is sparse. There are only two ozone stations operating in Antarctica; Syowa Station (69°S) and Amundsen-Scott (90°S), where the total ozone has been observed in sunlit months only. To make up this deficiency extensive observations were carried out at Syowa Station from February 1982 to January 1983 as a part of the international project of Middle Atmosphere Program (MAP). This paper gives some preliminary results of this observation.
