چکیده

in the present study, air quality analyses for ozone (o3) were conducted in shiraz, a city in the south of iran. the measurements were taken from 2011 through 2012 in two different locations to prepare average data in the city. the average concentrations were calculated for every 24 hours, each month and each season. results showed that the highest concentration of ozone occurs generally in the afternoon while the least concentration was found in the morning and at midnight. monthly concentrations of ozone showed the highest value in august and june while the least value was in december. the seasonal concentrations showed the least amounts in autumn while the highest amounts were in spring. relations between the air pollutant and some meteorological parameters were calculated statistically using the daily average data. the wind data (velocity, direction), relative humidity, temperature, sunshine periods, evaporation, dew point, and rainfall were considered as independent variables. the relationships between concentration of pollutant and meteorological parameters were expressed by multiple linear regression equations for both annual and seasonal conditions using spss software. root mean square error (rmse) test showed that among different prediction models, stepwise model is the best option.
