SURFACE OZONE CONCENTRATION AND ITS CORRELATION WITH METEOROLOGICAL PARAMETERS IN AN INDUSTRIAL URBAN COASTAL AREA ALONG THE BAY OF BENGALB. MUTHULAKSHMI, S. JOHNSON JEYAKUMAR AND I. KARTHARINAL PUNITHAVATHY
This paper tends to study the two year long continuous measurement of gaseous pollutant ozone present in the ambient air at an industrial urban coastal area along the Bay of Bengal. Ozone (O3),an allotrope of oxygen is one of the most powerful oxidants that occur naturally in trace amounts in the Earth's atmosphere. Surface O3 is measured for a period from October 2014 to September 2016 at an industrial area. The observed concentration of ozone pollutant at study area is a function of time. Diurnal variation of O3 reveals that Ozone levels are maximum during afternoon hours and minimum during midnight hours. On a seasonal scale, it is observed that the surface ozone concentrations are higher in summer and pre-monsoon and lower in North-East monsoon and winter respectively. Surface ozone and its variation with meteorological parameters at an industrial coastal area were analyzed through the sequential pattern.
