224 LES simulations over idealized building arrays were performed at 0.5 m resolution horizontally and vertically

• •8 plan area densities from 0.0625 to 0.64, covering most urban configurations in global cities.
• •2 horizontal configurations (staggered and aligned)
• •7 building height distributions with Hstd = [0m,2.8m,5.6m]
• •2 wind directions (perpendicular and oblique to building blocks)

314 LES simulations over realistic urban neighbourhoods were performed at 0.5 resolution vertically and 1m horizontally.

• •A representative range of urban densities is considered (0.05-0.75) in global cities.
• •Realistic urban geometries from 62 cities in 20 countries.
• •Covering multiple wind directions.
