Abstract

We report on one-year continuous measurements of aerosol black carbon (BC) at the EMEP/GAW regional air quality station on Mt. Krvavec in Slovenia, where ozone concentration has been monitored routinely since 1991. The results show several characteristic BC and O-3 concentration patterns. At times we observe a negative correlation: high BC and low ozone can be attributed to the mixing of fresh polluted air up to the temperature inversion layer or to the local pollution sources, while low BC and high ozone can be due to down-welling from the free troposphere. At other times we observe a positive correlation between these two species, as a result of the transport of polluted air from regional sources, in the absence of strong temperature inversions.
