Abstract

Simultaneously modelling the measured NOx and NO2 concentrations is a challenge for many atmospheric dispersion models including the Operational Street Pollution Model (OSPM®). In the present study two streets in Copenhagen, Denmark are modelled using an improved version of OSPM. The improved model contains a new parametrization for the roof-level wind speed with the aim of better representing the NOx concentrations. It is moreover the aim to update the reaction rates for the NO-NO2-O3 chemistry in the street canyons. This is still work-in-progress and thus not presented here. The results show a significantly altered wind direction dependency of the average wind speed for one street canyon and less impact on the other street canyon. The improved wind speed model does however not lead to direct improvements in the street level concentrations.
