Urban Air Quality Modelling

These studies are generally based on index map sections that integrate data on emissions from road networks, industrial facilities, residential/commercial sectors, biogenic emissions, airports, etc.

Dispersion models are configured based on features specific to the urban environment, i.e. canyon effects for roads lined with buildings, urban weather contexts (heat islands), urban photochemistry, regional pollution forcing, etc. The results of these simulations are used to produce GIS-based air quality maps at urban scale, with a sufficiently fine-scale resolution to be able to zoom in down to street scale.

Furthermore, these studies are often the first step in deploying the URBAN’Air operational system, developed to monitor and predict air quality at whole-town scale.
