Short summary
NO2 is a pollutant that regularly exceeds its limit values in European cities. We developed a compact, mobile laser spectrometer that measures NO2 concentrations and installed it on a tram in Zurich. Mobile operation resulted in NO2 concentration data with high spatio-temporal resolution. The data were validated against fixed air-quality monitoring sites and provided detailed insights into the spatio-temporal concentration distribution of NO2 in an urban environment.
