Vertical Distribution of Atmospheric Ozone at Tateno and Other Four Stations in and near Japan

Abstract

Vertical ozone distributions are estimated from Umkehr observations at Tateno, Sapporo, Kagoshima, Torishima and Marcus, in and near Japan, according to Walton's method A. The effects of observational errors and of the assumption of ozone amount below 12km height on the result are discussed at first. Comparing the results by the method A with those by the method B, it is revealed that differences between the results by the two methods seem to be caused partly by the assumption of ozone amount below 12km.
At Tateno, ozone in 12-24km height is about 40% of total ozone or more, and ozone in 24-36km is about 40% of total or less. Correlation coefficients of the ozone amount in 12-24km height and that in 24-36km with 200mb height are given, and relations between vertical distributions of ozone and temperature in August are shown. Seasonal variations of ozone in each layer at the five stations are discussed qualitatively.
