Wind-tunnel LES validation data for an idealised European city, a cube array and approach boundary layers (CEDVAL-LES)
BenchmarkLabOn request
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.

The Architectural Institute of Japan (AIJ) urban wind environment benchmark suite: wind-tunnel and field data for cases A–M, from a single high-rise building and cube arrays to real districts such as Shinjuku and Niigata, many with STL geometry. Widely used to validate CFD for pedestrian-level wind and dispersion.
DTRA/DHS field study in July 2003: ten 8-hour intensive periods of SF6 releases in the central business district, sampled by 194 bag samplers and 25 fast-response analysers, with winds and turbulence measured at about 100 sites. A classic real-city dispersion benchmark.
Basel Urban Boundary Layer Experiment, 2001–02: a year-long network of energy-balance towers across urban, suburban and rural sites, with a June–July 2002 intensive period adding a wind profiler, sodar/RASS, lidar, a street-canyon tower and four SF6 tracer releases. A reference for urban roughness-sublayer turbulence and energy balance.
Classic multiscale urban dispersion campaign: SF6 and perfluorocarbon tracer releases with meteorology around a single building, across the downtown grid and over the wider city, mostly in stable night-time conditions. Files are openly downloadable by IOP.
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.
Meteorology and air quality field campaign in London in 2011-12, with multiple sites and intensive observations during the 2012 Olympics. Useful for urban boundary-layer and air quality studies; individual datasets are available via the paper authors.
