Wind-tunnel dispersion from continuous and puff releases in an idealised European city (COST ES1006 Michelstadt)
BenchmarkLabOn request
Flow and concentration data in the 1:225 Michelstadt model for seven ground-level release scenarios, two wind directions, continuous and puff releases; the blind-test benchmark for emergency-response dispersion models.

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.
