The purpose of the paper is to present the variation of total ozone concentration over Dumdum at Kolkata, India during different seasons. It is concluded that the trend of ozone concentration during different seasons are different. A critical analysis is done and following important results are obtained. (i) The total ozone concentration increases during the pre-monsoon and winter periods. During pre-monsoon period rate of formation of ozone increases sharply with the rise of surface temperature. (ii) TCO decreases during the monsoon and post-monsoon periods, throughout the period of study. During monsoon period rate of depletion of ozone increases and during post-monsoon period rate of depletion of ozone decreases with the increase of temperature. (iii) Possible explanations are also presented.
