The goal of this work is the analysis of particulate matter with aerodynamic diameter less than 10 mu m (PM10) recorded in the urban area of Volos, a medium-sized Greek coastal city on the eastern seaboard of Central Greece. For this purpose, concentration measurements of PM10, for a seven-year period (2001-2007) are analyzed. Air pollution data were obtained by a monitoring station, fully automated, that was established by the Hellenic Ministry of the Environment, Energy and Climatic Change, in order to measure air pollution levels in Volos. %26lt;br%26gt;The extracted findings showed that the mean diurnal variation of the examined air pollutant concentrations within the cold and the warm period of the year show a double peak structure with respect to morning and evening hours. Additionally, the intra annual variation of PM10 concentrations shows a double peak pattern. The dominant peak is observed in February and the secondary peak in May/June. Besides, the role of wind seems to be significant as the PM10 exceedances are strongly associated with predominant wind directions.
