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.
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.
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).
Eddy-covariance flux and meteorological observations from Swindon, 2011-2013, with SUEWS forcing files. Useful for urban surface energy balance model evaluation.
Long-running tall-tower eddy-covariance records of momentum, sensible and latent heat and CO2 over downtown and suburban Indianapolis, with raw 10 Hz data for turbulence statistics.
