Abstract :
In this research measuring ozone concentration in air quality control Company at Aqdasieh station,and meteorological parameters at Resalat station, was compared and investigated. This investigationwas performed for 7 months (from Oct. 2007 to Apr. 2008). The average daily Ozone concentrationshowed the least quantity of Ozone in early morning and late night air. Comparing the sunshineradiation with variation of Ozone concentration indicated that these two items have direct relations.Increasing the sunshine radiation concludes the increasing of photochemical activity and consequentlyincreasing the Ozone concentration. Investigating the monthly average Ozone concentration showedthat the least registered amount of Ozone was during these 7 months of measurement in Azar(November) and the most registered amount of Ozone occurred in Farvardin (April). The mostimportant factor of main increasing happened in April and in the solar radiation and photochemicalactivities.
