Study on Atmospheric Ozone in East Asia with Satellite Observation

The atmospheric ozone in East Asia has been studied with satellite remote sensing. The relationship between at-mospheric ozone and tropopause height is analyzed and its response to weather processes has been discussed. The mean deviation between the total atmospheric ozone content derived from TOVS data and that got from ground-based Dobson spectrophotometer observation is 3.67%. The total atmospheric ozone content increases with the latitude increasing in East Asia. The correlation coefficient between total ozone content and tropopause height is negative. The average is 74%. The total atmospheric ozone content is closely related to weather processes. Ozone con-tent increases while arctic air mass invading and decreases while tropic air mass coming.
