Urban scale air quality assessment with a harmonized multi-scale model

The performances of an open-source multi-scale air quality model are discussed in this work. The model CAMx-LPiG is implemented to assess air quality in urban areas, with a special focus on road traffic emissions. We aim for developing a flexible and adaptable modelling tool, able to capture from intra-urban up to basin scale processes of both primary and secondary pollutants. Such tool could become a standard to monitor air quality and assess the effects of mobility policies in urban areas.
