Annotation	In this paper, a wind-tunnel study on dispersion of a tracer gas emitted from a ground-level line source positioned within complex obstacle arrays is presented. The models consisted of courtyard buildings blocks with pitched roofs and of uniform and non-uniform heights. Tracer exchange between the street canyon cavities and surrounding flow was studied by simultaneous point measurement of flow and tracer concentration. While there was found a significant impact of the roof-height variability on the tracer exchange rate from the canyon in the case of wind approaching perpendicularly to the along-canyon axis, in the case of the oblique wind the impact was insignificant.
