Advective horizontal and vertical scalar fluxes are computed from measured data for five flow directions. The highest advective contaminant fluxes are measured in the bottom parts of street-canyons. The important role of the vertical turbulent scalar flux in ventilation of intersection is expected. Quadrant analysis of vertical flux of longitudinal momentum is used to determine a domination of sweep or ejection events above the intersection.
