WebDispersion modelling is among the most common tools for assessing air quality levels in urban areas due to that fact the available monitoring data provide only fragmented images of air quality. The last decade has witnessed renewed interest in steady-state Gaussian-like dispersion modelling, which is the primary focus in urban air quality research. WebThe dispersion area is usually composed of three distinct zones: The initial mixing zone, the full mixing zone and the far field zone [ 6 ]. In this work, we focus on the third zone where dispersion is considered longitudinal and one-dimensional in the flow direction.
