Abstract

Deep street canyons are a common feature of densely populated urban areas in Southern Europe. In these locations, multi-storey residential and/or office buildings surround relatively narrow streets reducing natural air ventilation. That may result in high concentrations of traffic-related pollutants, such as CO, in heavily congested streets and/or streets with high density of two-stroke motorcycles. Well calibrated and user-friendly dispersion models are needed for assessing air quality under these conditions. In the present study, two different modelling techniques are used to simulate CO concentrations at different heights within a deep street canyon (Via Nardones) in Naples, Italy.
