摘要：In the present study air quality analyzed for Carbon monoxide (CO), 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 for the city. Results showed that the highest concentration of Carbon monoxide occurs generally in the Night while the least concentration was found at in the morning and mid-night. Monthly concentrations of Carbon monoxide showed the highest value in December and the least value in May. The seasonal concentrations showed the least amounts in spring while the highest amounts in autumn. Relations between the air pollutant and some meteorological parameters were calculated using, temperature, sunshine periods, evaporation, dew point and rainfall the daily average data. The wind data (velocity, direction), relative humidity 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. RMSE test showed that among different prediction models, stepwise model is the best option.
