Comparative study of measured and modelled number concentrations of nanoparticles in an urban street canyon

For the first time, this work demonstrated that the competing influences of transformation processes on nanoparticles negate each other’s effect and hence can be ignored in street–scale dispersion modelling. This paper supported the hypothesis embedded in widely deployed ‘Operational Street Pollution Model (OSPM)’ (Matthias Ketzel: mke@dmu.dk). The findings have helped substantially aerosol measurement analysts and dispersion modellers to take improved account of street-scale transformation. In turn, this assists policy makers relying on the outputs of such models.
