2D PIV wind-tunnel data of turbulent boundary layers over twelve urban roughnesses with different frontal and plan solidities. Useful for studying turbulence statistics and parameterising urban roughness.
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.
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.
Raw simulation data and MATLAB scripts for a multi-scale analysis of flow over heterogeneous urban environments. Useful for urban boundary-layer and roughness research.
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.
Modified source code, simulation directories and postprocessing for multi-layer SURFEX-TEB coupling with Meso-NH for urban climate of high-rise cities. Useful for mesoscale urban modelling.
