Intercomparison of Atmospheric Dispersion Models Applied to an Urban Street Canyon of Irregular Geometry

An Introduction to Atmospheric Pollutant Dispersion Modelling

“…Compared to other street models, AEOLIUS/AEOLIUSF is not as commonly used in contemporary settings. Its accuracy is middle-of-the-range, being higher than STREET models but lower than SEUS models [24].…”

“…The choice of pollutant dispersion model plays a key factor in the accuracy of the results obtained [24]. The available modelling techniques were reviewed by Daly and Zannetti [25] over a decade ago, and more recently by Barratt [26] and Colls and Tiwary [27].…”

Quantification and attribution of urban fossil fuel emissions through atmospheric measurements

“…But also even more complex models are developed (such as LES) that can be used specifically in build-up areas and account for the impact of buildings and street orientation on the atmospheric transport (e.g. (Dezzutti et al, 2018;Tolias et al, 2018). However, more detailed models require more input data which, if uncertain, add additional uncertainty to the results.…”

Research on air pollution characteristics and planning strategy of urban street environment

“…The investigation of air pollution in urban street environment has always been a difficult task due to the diverse arrangement of buildings, the uncertainty of the location of pollution sources and the complex turbulence characteristics of urban canopies [10] . Model simulation and field measurement are two main methods applied to the study of urban street air pollution [11] . In model simulation studies, urban street environment is often idealized, and there are unexpected differences between the results of numerical models and the actual situations [12] .…”
