The measurements were performed by a semi-online field OC/EC analyzer with a two-hour resolution that sufficiently showed the diurnal variability of OC/EC. The seasonal, daily and diurnal behaviour of the EC and OC were studied using an analysis of the collected data. The results of a one-year campaign (Sep 2009 – Aug 2010) provide various seasonal patterns of the EC and OC concentrations characteristic for a suburban site in Central Europe. Different sources of carbonaceous aerosols during the various seasons were identified. The winter main sources were probably traffic (mainly EC) and residential heating (both EC and OC). On the other hand, the main EC source in summer is traffic, while the major OC source may be secondary organic aerosols. Winter concentrations were significantly higher than in other seasons.
