Abstract:
Manmade structures necessary to accommodate fast growing populations change the average temperature of urban environment leading to warmer local climate. Urban temperatures might exceed those in rural areas with up to 10 0C and it is estimated that the difference might increase over the next 50 years. Studies are carried out to evaluate the effect of temperature on urban air quality as well as the effect of air pollution on urban temperature. The objective of the present paper is to study the correlation between meteorological conditions and pollutant concentration in urban environment. Monitoring pollution stations provided data for meteorological parameters and pollutant concentrations, respectively. Pollutants considered have been SO2, CO, NOx and O3 their hourly evolution has been studied along with meteorological parameters for 12 months (January - December 2006). A double-cross comparison has been made between data sets form 2 urban stations and 2 suburban stations. Correlation has been used to study the cause-effect relation between urban temperature and pollutant concentration.
