Sažetak
In the paper a CFD-based micro scale air quality model called ENVI-met will be presented. ENVI-met distinguishes itself
from other CFD-models due the implementation of a detailed vegetation model which describes the interaction of local vegetation,
not only on the wind field, but also on the thermodynamic processes and the diffusion and deposition of gases and particulate
matter. This makes the model particularly suitable for a recent research programme initiated by the Air Quality Innovation Project
(IPL), founded by the Dutch Ministry for Transport, Public Works and Water Management (Rijkswaterstaat) and the Ministry of
Housing, Spatial Planning & the Environment (Ministry of VROM). One of the seven branches of the IPL-project is to investigate
both by measurements and modelling the effect of line vegetation along a motorway on local air quality. Recently the model results
have been compared to a first measurement campaign.
