Short summary
This paper presents a comprehensive summary of roadside measurements using a mobile laboratory, equipped with state-of-the-art instrumentation. Pollution gradients were observed for particle number, black carbon, organics, some metals, and gases at four different highway environments. Flow dynamics appeared to be an important factor, however, at the most open site, condensation of semi-volatile organics was observed. The fleet average NO2 emission factor increased over the last decade.
