Abstract: 

Ozone discovered in 1839 by Shonbine. Until 1850 anyone knew that Ozone is one of the gases that makes atmosphere. Ozone makes the %  of atmosphere volume. Ozone distributed non homogen in the atmosphere. About %10 in the troposphere and %90 in stratosphere. Ozone is the most chemical photo oxidant in the atmosphere so National America Air Quality Standards based on it. If the density of ozone more than 0.12 part per million, it will be dangerous. Tropospheric Ozone is a pollutant and changes primary pollutants to secondary pollutants. In this paper we analyzing Ozone data during 1995- 2005. Esfahan Ozone metric station located in 51 o27 ´East and in 32 o47 ´North in the south part of city. The elevation of it is 1550 m.
In this paper we determine the trend of Ozone by statistical software such as SPSS& EXECL. We conclude that Total Ozone has not significant correlation with weather stability but temperature and wind speed in upper level especially in 50 milibarr have strong effect on it. Surface ozone has strong correlation with surface weather conditions especially with maximum temperature and sun shine.
