Time-resolved wind-tunnel velocity data built to validate LES: three approach boundary layers, flow and puff dispersion in a cube array, and the 1:225 idealised Central-European city Michelstadt with flat or slanted roofs.
224 large-eddy simulations of flow over idealised building-block arrays. They systematically vary plan-area density (8 values, 0.0625 to 0.64), aligned and staggered layouts, 7 building-height distributions, and perpendicular or oblique wind. A parameter sweep for canopy parameterisation and model validation.
Turbulent inflow data of a rough atmospheric boundary layer for LES of Michelstadt, the semi-idealised Central European city model from the University of Hamburg wind-tunnel test cases (CEDVAL-LES), not the real town.
LES output of an urban canopy and dense vegetated canopies over varying terrain complexity, for roughness-sublayer momentum statistics and TKE budgets.
