A percolation framework maps heatwave losses in lower-exposure street networks: code and derived data

This record contains the code and derived data supporting the manuscript “A percolation framework maps heatwave losses in lower-exposure street networks”. The archive covers 264,174 street segments and 6,205 Lower Layer Super Output Areas across London, Birmingham, Bristol, Manchester and Newcastle. The archive includes road-level Heat Exposure Index outputs, city-level Cool Network Index and threshold-integrated Cool Network Index summaries, deprivation and sensitivity results, derived land-surface-temperature scenario inputs, figure and Supplementary Information source tables, workflow documentation, a data dictionary and SHA-256 checksums. Running `python run_pipeline.py` verifies the principal reported values and checks all packaged Python sources. The downstream stages that can be recomputed from archived data are documented in `REPRODUCE.md`. Raw LiDAR tiles, complete hourly shadow rasters and provider-supplied inputs that cannot be redistributed are not included. Their access routes and expected locations are documented in `data/00_manifests/input_manifest.csv` and `docs/RAW_DATA_SOURCES.md`. Licensing terms for the code, author-generated data and third-party-derived geometry are specified in `LICENSE.md`.
