Wind tunnel measurements and LES modelling of realistic urban wind flow over downtown Montreal

This dataset provides Cobra probe wind tunnel measurements and Large Eddy Simulation via LES-DT of the flow over a realistic downtown Montreal model. Two wind directions are included, SW and NE. All velocities are in m/s and Reynolds stresses in m²/s² at model scale.

The package contains:

• the city geometry (STL) for each wind direction
• 288 locations with raw and filtered velocity time series (U, V, W) based on entropy-based sensor placement
• 32 profiles at fixed (x, y) stations, raw and filtered, with per-height statistics
• repeatability (UQ) pairs: selected probes measured twice, raw and filtered, with statistics
• LES-DT probe time series, raw and Cobra-filtered, with matching statistics
• LES mean fields (UMean, UPrime2Mean) on the seven measurement heights
• interactive 3D HTML viewers of the city with the probes and with the profile stations

Wind-tunnel filtering removes dropout samples with speed below 0.01 m/s. LES filtering keeps samples with speed at least 2 m/s and direction within 45 degrees of the oncoming wind (+x), based on the Cobra probe accuracy thresholds. Statistics files report U, V, W, uu, vv, ww, k and TI for the raw and filtered signals.
