Several methods to determine the aerodynamic characteristics of a site through analysis of its surface form (morphometry) are considered in relation to cities. The measures discussed include zero-plane displacement length (z d), roughness length (z 0), depth of the roughness sublayer, and aerodynamic conductance. A sensitivity analysis is conducted on seven formulas to estimate z d and nine to estimate z 0 , covering a wide range of probable urban roughness densities. Geographic information systems developed for 11 sites in 7 North American cities are used to characterize their morphometry-the height, shape, three-dimensional area, and spatial distribution of their roughness elements (buildings and trees). Most of the sites are in residential suburbs, but one is industrial and two are near city centers. This descriptive survey of urban geometric form is used, together with the morphometric formulas, to derive the apparent aerodynamic characteristics of the sites. The resulting estimates of z d and z 0 are compared with values obtained from analysis of wind and turbulence observations. The latter are obtained from a survey of approximately 60 field studies and 14 laboratory studies of real and scale model cities. Despite the comprehensive nature of the survey, very few studies are found to be acceptable and their scatter is large, hence they do not provide a standard against which to test the morphometric algorithms. Further, the data show only weak relations between measured z d and z 0 and roughness density. The relative merits of morphometric and wind-based estimates of aerodynamic parameters are discussed. Recommendations are made concerning the choice of method to estimate z d and z 0 in urban areas and their most likely magnitude.

The dispersion data in neutral stability condition were picked out of a series of lowlevel tracer experiments conducted in several urban areas, and were analyzed on the basis of Gaussian plume model. Dispersion parameters calculated from the tracer data were related to several readily measured or derived meteorological data. The results were compared with those of previous dispersion experiments conducted in urban areas. Under neutral stability condition the vertical standard deviation of concentration correspond to C to D stability classes of the Pasquill-Gifford curves.On the other hand, the crosswind standard deviation of concentration scattered between A and D-E stability classes.
