Ozone in the troposphere is a pollutant, a constituent of smog. Ground level ozone is regarded as a pollutant by the World Health Organisation. A high concentration of tropospheric ozone can contribute to a potentially important climate forcing, which needs to be properly assessed. In this study Surface ozone measurement was estimated at vadasery, which is one of the heavy traffic prone area in Kanyakumari district has been analysed for a period of 12 months .Ozone measurements was carried out by using a hand held ozone monitor from Aeroqual. In Diurnal variation cycle shows maximum value of ozone around 14.30 hrs and minimum around 5.30 hrs. The highest ozone concentrations was recorded in April ( 0.0583ppm) and minimum in June (0.010ppm) .Seasonal Variation of surface ozone showed maximum values during winter (0.05065ppm) and minimum values at Southwest monsoon(0.01411ppm).
