Urban ventilation screening fields and municipal climate-analysis layers for Linz, Austria

This data set accompanies the article "Benchmarking urban ventilation screening against large-eddy simulation: an evaluation protocol for a Central European city" (Hochebner, Schneider, Tötzer). It contains nine low-cost urban ventilation screening fields for Linz, Austria, computed for two westerly inflow cases (12 June 2011, 08:00 UTC/270° and 13:00 UTC/284°). The fields cover:

• frontal area density
• canopy height
• terrain resistance
• an equal-weight resistance overlay
• least-cost-path and circuit-theory connectivity
• diagnostic terrain flow with and without directional canopy shelter
• a directional canopy shelter index

The fields are provided on their native grids (GeoTIFF) and resampled to the 10 m grid of the PALM reference simulation (NetCDF). The result tables (CSV) report each field's spatial correspondence with the simulated retained wind availability, paired block-bootstrap comparisons between fields, directional-holdout and cross-validation scores, scale dependence and planning-prioritisation performance. They also include results for two layers of the municipal urban climate analysis of Linz, which are available as open data from the City of Linz: https://www.data.gv.at/datasets/8a392d45-1d0c-43d6-a736-944ca28fe2aa?locale=de

The PALM reference data are available from the authors upon request.
