Building-resolved LES wind fields for Beijing, Shanghai, Guangzhou, Shenzhen and Hong Kong (U3DWind)
Simulation
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.
Half-hourly time series, fluxes, quadrant and wavelet results behind the figures of the paper, from the 325 m Beijing tower and the 102 m Xianghe tower, July 2017.
Hourly 2024 observations from 48 automatic weather stations across Shenzhen, including wind speed and direction, temperature, humidity and pressure. Useful for urban climate and wind analysis.
Processed turbulence statistics and 10 Hz fluctuation records for four case studies from the 325 m Beijing tower and the 102 m Xianghe tower, July 2017.
