摘要：

We report on measurements from an automated air pollution and meteorological station operating in the city center of Ljubljana, Slovenia. Aerosol black carbon, SO2, NO and NO2 were measured continuously on a 30-min timebase. Filter samples integrated over periods of 1-3 days were analysed for total particulate carbon and sulfur species. Large variations of pollutant concentrations were seen, correlating with emission source activity and periods of meteorological stagnation. Correlations between primary (BC) and secondary (S(P)) species were seen, suggesting a rapid SO2 to sulfate conversion mechanism. We discuss the influence of meteorology and primary emission activity on air quality in the city.
