Regression Analysis And Forecasting Hourly Concentration Of Surface Ozone In Chennai, Tamil Nadu

Observed Ozone Concentrations are valuable indicators of possible health and environmental impacts. They are also used to monitor changes and trends in the source of Ozone and its precursors. The influence of meteorological variables is a confounding factor. The paper examines Ozone concentration and meteorology in Chennai at Koyambedu which is a major big Bus terminus. We were the first researchers measuring Ozone and meteorological parameters in this site. We have made an effort to understand seasonal variation of Surface Ozone and meteorological parameters. This will be very useful for further research and future researchers. A non-linear regression model has been designed to forecast hourly average ground level Ozone concentration on the next day in Chennai using meteorological data. For this purpose, a number of regression models were considered. The selection of final model was based on extensive analysis and literature. One day hourly forecast of Ozone Concentration was made by the meteorological parameters which are very closely correlated to ozone.
