In this research 25 air quality monitoring stations were carefully selected in Coimbatore city based on the traffic count, nature of traffic, busy v road intersections with traffic signals having maximum vehicle idling time, traffic congestion and nearness to commercial & industrial places. The stations were selected in the heart of the city, residential areas, industrial areas and outskirts of the city along the main intersections covering the entire city. The measurements of wind speed and its direction, temperature, humidity, rainfall and solar radiation are important parameters used in the study of air quality monitoring results and to further understand the chemical reactions that occur in the atmosphere. High volume sampler was used for collecting the air samples and analysis was done in the laboratory for Total suspended Particulate matter (TSPM), respirable particulate matter (RPM), sulfur dioxide (SO2), Nitrogen oxides (NOx) and carbon monoxide (CO). Periodic data collection of the air pollutant concentrations were carried out. Regression analysis has been done to establish the effect of the meteorological parameters with the concentration of air pollutants. Traffic survey was also carried out. Response surface methodology (RSM) was adopted to find out the influence of the meteorological factors on the concentration of the air pollutants.
