Increasing concentration of tropospheric ozone is a serious air pollution problem faced commonly by the urban people. The present study emphasizes on variations of air pollutant concentrations viz., ozone (O3), nitrogen oxides (NOx), carbon monoxide (CO), sulfur dioxide (SO2) and black carbon (BC) at a tropical urban site located in the Deccan plateau region with semi-arid climate. The air monitoring site revealed typical diurnal/seasonal trends attributing to the complex chemistry of surface O3 formation from its precursors. Role of SO2 in the formation of free radical (HO2●) and its impact on O3 concentration is distinguished part of study. The results showed the highest mean O3 in summer (57.5±15.2 ppbv) followed by winter and monsoon. Observations of BC aerosols showed the highest mean values during winter (8.2±2 μgm-3) and the lowest in monsoon (4.2±1 μgm-3). Besides local influences, long range transport of air masses was also studied by simulating back trajectories at different elevations during the study period. Furthermore, statistical analysis like Pearson correlation and modeling were evaluated. Statistical modeling was performed with both linear (regression) and non-linear (neural network) methods to predict the O3 concentration influenced by the other independent variables.
