Short summary

We present results from the long-term measurements (5 years) of highly time-resolved atmospheric PM₁ composition at an urban street canyon site. Overall, the results increased knowledge of the variability of PM₁ concentration, composition, and sources in a traffic site and the implications for urban air quality. The investigation of pollution episodes showed that both local and long-range-transported pollutants can still cause elevated PM₁ and PM_2.5 concentrations in northern Europe.
