Displacement height (d $d$) and, particularly, roughness length (z0 ${z}_{0}$) are essential urban aerodynamic parameters for earth system modeling the climatic impact of urbanization. Urban heterogeneities, inherent to real cities and impacting significantly the transfer of energy, mass and momentu...
