Wind tunnel measurements of concentration and velocity in urban geometries with trees

This dataset contains concentration and velocity mesurements performed in the aerodynamic wind tunnel of the Ecole Centrale de Lyon (France). An idealized urban district was simulated by an array of blocks, and two rows of model trees were arranged inside a street. Reduced scale trees were chosen to mimic a realistic shape and aerodynamic behaviour.Three different spacings between the trees were considered: "zero" (no trees), "half" (14 cm distance between the tree trunks) and "full" (7 cm distance between the tree trunks). The dataset includes: concentration and velocity measurements performed within a street canyon, under various geometries and wind directions; the characterization of the boundary layer above the buildings; the characterization of the tree drag. The detailed description of the dataset is contained in the document Info_dataset.pdf
