"Releases of harmful gaseous materials are of high concern of decision making bodies. The understanding of short-range dispersion of air-borne substances within the urban canopy is crucial to predict spread of such pollutants. The simplest description of the transport and dispersion of a passive contaminant is the equation of advection. The terms describing purely advective and turbulent transport of the passive contaminant appear after some modification of this equation. The method developed by the researcher team of Wind Engineering Center of Tokyo Polytechnic University allows to measure flow and concentration fields simultaneously. Direct calculation of advective and turbulent fluxes is possible from obtained datasets. The comparison of those fluxes within 6 different arrangements of idealised urban canopies is shown and the importance of a proper determination of the turbulent fluxes at the edge of the plume and above the roof top level is emphasised." . . .
