In order to study pollution dispersion in built up area, aeraulic simulation at reduced scale in a boundary layer wind tunnel is intensively used at CSTB. The experimental set up and the associated procedures are described here. A comparison with complementary approaches developed at CSTB, numerical simulation and full scale measurements using tracer gas release is also provided.
