Abstract: In the framework of the Interreg-IV 'PM-Lab' project a local-scale exercise was set up to evaluate air pollution in terms of particulate matter (PM) within the centre of Liège, Belgium (pop. 190,000). Sixteen sites distributed on a boulevard and its side streets were selected to determine the spatio-temporal variation of PM concentration in this traffic-dominated area. In addition to the in situ measurements numerical simulations were performed by means of AUSTAL2000. The performance of this Lagrangian dispersion model was checked through some basic qualitative and quantitative comparisons. As the model was able to detect highest PM concentrations both in space and time, test scenarios of emission reductions were also run in order to examine the impact of different traffic related measures.

Keywords: particulate matter; air quality; urban air pollution; atmospheric dispersion modelling; traffic emissions; vehicle emissions; emission reduction; Belgium; numerical simulation; Lagrangian models.
