The atmospheric concentrations of several atmospheric pollutants: SO2, PM10, and meteorological parameters have been measured at several locations in Konya city, Turkey since 1990. The objective of this work is to estimate the effects of meteorological factors on the air quality levels for this city. The measurements are achieved using 4 fixed stations and 1 mobile station to cover several important areas of Konya. The relationship of pollutants concentrations to five major meteorological parameters is assessed, with a particular focus on the meteorological conditions that create high- pollution episodes.
The results showed that, wind speed, relative humidity and temperature were found to have an influence not only on pollutant concentrations but also on the correlation between pollutants. At higher wind speeds, from the surrounding area was entrained by the wind, thus contributing to ambient particulate matter levels. For SO2and PM10 the highest average concentrations occurred at humidity above 75-80%, atmospheric pressure above 890-910 hpa and lower wind powers than 1.2 m/s during winter period.
