Traffic density, wind and air stratification influence concentrations of air pollutant NO2
Traffic density is the most important factor for much the air pollutant nitrogen dioxide (NO2). However, weather also has an influence, according to a study by TROPOS, which evaluated the influence of weather conditions on nitrogen dioxide concentrations in Saxony 2015 to 2018 on behalf of LfULG. It was shown that wind speed and the height of the lowest air layer are the most important factors that determine how much pollutants can accumulate locally.
