Vertical Ozone Distribution at Syowa Station, Antarctica, in 1966

"Vertical distribution of ozone at Japanese Antarctic station Syowa, 69°00′S, 39°35′E, was observed by means of carbon-iodine type chemical ozonesondes. Main purpose of this report is to give the results obtained by the soundings during the period from March 1966 to January 1967. Describing the data reduction method with some related problems, 28 vertical ozone distributions are given in ozonagrams and tables. A smoothed time-height cross section of ozone partial pressure is presented, with discussion on the seasonal characteristic ozone profiles and the ozone changes in each layer during the stratospheric sudden warming in 1966. Also, it is noted that the tropopauses are found 1-2km above the level where ozone begins to increase upwards into the stratosphere.
