Abstract(s)The City of Viana do Castelo in Portugal has developed an air quality program, which includes prediction of pollutant concentration for NO2, CO, PM10, O3 and C6H6. A range of numerical models were used to produce the concentration maps: the ADMS-Urban model for the pollutants dispersion; the Hills model to calculate air flow and turbulence over complex terrain, including the effects of variable surface roughness; the CORINAIR v.5 to estimate traffic emissions. This paper presents the methodology developed to validate the modelled results. Predicted concentrations were compared against measured concentrations of a chosen pollutant: Carbon Monoxide, CO. Five comparison statistics were calculated for three test points in order to find out the quality of the modelled results. Additionally, a hourly profile of predicted versus measured concentrations was developed.
