Embedded LES of the urban boundary layer with accelerated turbulence generation
Simulation
Data accompanying a study of embedded large-eddy simulation of the atmospheric boundary layer over an urban region using accelerated turbulence generation. Useful for LES inflow and urban boundary-layer modelling.

720 time-mean lattice-Boltzmann LES cases at 10 m resolution, 144 per city, spanning 16 wind directions, 3 reference speeds and 3 seasonal profiles, with 3D mean velocity and TKE plus building, terrain and footprint geometry. Very large (about 25 TB).
Large-eddy simulations of turbulent airflow over 314 realistic urban neighbourhoods from 62 cities in 20 countries, with plan-area densities from 0.05 to 0.75 and several wind directions. Provides canopy-averaged statistics and flow fields, which are useful for canopy parameterisation, model validation and machine learning of urban wind.
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.
