The impacts of Black Carbon (BC) on adverse public health and Earth’s climate system have been recognized and evidenced in recent decades. Most of the studies on BC were conducted in urban/traffic areas. There are relatively few studies using real-time measurements of BC at rural background areas, especially in Central Europe. This study is a 5-year characterization of BC from biomass burning (BCbb) and fossil fuel combustion (BCff) at the National Atmospheric Observatory Košetice (49°35ʹ N, 15°05ʹ E), in central Czech Republic. The measurements of BC in PM10 were performed at 4 m above the ground with a multiple wavelength aethalometer (AE31, Magee Scientific). Paralell measurement of trace gases (NO2, NOx and SO2), biomass burning tracers (levoglucosan and mannosan) and meteorological parameters (temperature, wind speed and direction) were also performed at the station.
