Abstract: This study focuses on a 5-year measurement of equivalent Black carbon (EBC) at a regional background site in Central Europe. The aim is to identify the potential sources of EBC, especially fossil fuel (ff) and biomass burning (bb). Measurements of EBC in PM10 were performed from September 2012 to December 2017 at NAOK (National Atmospheric Observatory Košetice, 49°35ʹ N, 15°05ʹ E), central Czech Republic, with a 7-wavelength aethalometer (AE31, Magee Scientific). The aethalometer model, based on the wavelength dependence of light absorption (Angstrom coefficient), has been used to estimate EBCbb (EBC from biomass burning) and EBCff (EBC from traffic). The influence of local and distant sources has been investigated using the Conditional Probability Function (CPF) and Backward Trajectories Cluster Analysis (BTCA).\nClear seasonal, diurnal and weekly variations of EBC were observed at the NAOK that could be related to the sources fluctuations and transport characteristic. The higher concentrations of EBC were measured during winter (1.00 ±0.87 μg m-3) in comparison with summer (0.44 ±0.29 μg m-3).\n
