Use of ADMS-Urban to calculate high resolution air quality maps in urban areas

       

The urban dispersion model ADMS-Urban has been developed from the well known industrial source dispersion model ADMS 3. The model calculates concentration of pollutants at very high resolution (<20km) allowing explicit treatment of roads, including street canyons, point and area sources. The model includes a chemistry model and allowance for the effects of complex terrain. System features include easy links to road traffic models, the emission modelling toolkit (EMIT) and output via GIS in a form which allows assessment of the model output against air quality standards and objectives. After describing the main features of the model, topics covered will include model validation in London and Budapest, examples of model applications in air quality studies and examples of its use for air quality forecasting.
