MUNICH v2.0: a street-network model coupled with SSH-aerosol (v1.2) for multi-pollutant modelling

Abstract. A new version of a street-network model, the Model Urban Network Intersecting Canyons and Highways 2.0 (MUNICH v2.0), is presented. The comprehensive aerosol model SSH-aerosol implemented in MUNICH v2.0 to simulate street concentrations multiple pollutants, including secondary aerosols. implementation uses application programming interface (API) technology so that may be easily updated. New parameterisations are also introduced v2.0, non-stationary approach reactive particle deposition resuspension, parameterisation wind at roof level. test case over Paris suburb presented for evaluation illustrate impact functionalities. leads an increase 11 % PM10 concentration because formation. Using rather than stationary one decrease NO2 16 %. on built surfaces road resuspension pollutant canyons low.
