European coastal biodiversity replication: input data slices and analysis-ready intermediates (Xynthia, Xaver, Gloria)

Input data slices and analysis-ready intermediates for the replication study "European coastal biodiversity exposure under storm waves: WAVERYS vs regional CMEMS wave products at Natura 2000 marine sites." Code repository: https://github.com/annefou/european-coastal-biodiversity-replication This deposit exists to (a) pin the exact data versions the study used, since CMEMS reanalyses are periodically reprocessed, and (b) let the analysis and figure steps be reproduced without re-downloading the large source archives. It is NOT the primary reproduction path: notebook 01 in the repository downloads everything from source on first run. This is a preservation and fast-path layer. What's in this version (v3, 2026-05-30) The intermediates and the analysis schema changed in v3 to drop a methodological flaw discovered after v2: 02 no longer regrids the regional product onto the WAVERYS 0.2 deg grid; each product is now kept on its own native grid. Files are renamed accordingly: <storm>_waverys.nc (native 0.2 deg) and <storm>_regional.nc (native fine grid), replacing the v1/v2 <storm>_aligned.nc and <storm>_regional_native.nc. 03 now samples each product on its native grid per Natura 2000 site polygon site (continuous Hs delta), only one product resolves it (product choice categorically decisive), or neither does (out of scope, reported as coverage). results/per_site_delta.csv and results/headline_stats.csv carry new columns (tier, resolvable, n_tier_*, weighted_frac_differs_headline, weighted_coverage) reflecting the three-tier framing. Contents (~200 MB uncompressed): raw/ per-storm WAVERYS + regional CMEMS wave-height subsets (NetCDF, the exact spatial and temporal slices used). clean/ analysis-ready intermediates per storm: <storm>_waverys.nc and <storm>_regional.nc (each on its native grid), and <storm>_n2000_sites.parquet (marine Natura 2000 sites with Annex I habitat and Annex II species counts, GeoParquet). habitat and Annex II species counts, GeoParquet). results/ headline statistics, per-site delta table, threshold-X sensitivity, results/ headline statistics, per-site delta table, threshold-X sensitivity, and a summary CSV. and a summary CSV <storm>_n2000_sites.parquet (marine Natura 2000 sites with Annex I habitat and Annex II species counts, GeoParquet). results/ headline statistics, per-site delta table, threshold-X sensitivity, and a summary CSV. <storm>_regional.nc (each on its native grid), and <storm>_n2000_sites.parquet (marine Natura 2000 sites with Annex I habitat and Annex II species counts, GeoParquet). results/ headline statistics, per-site delta table, threshold-X sensitivity, and a summary CSV. Three storms: Xynthia (French Atlantic, Feb 2010; regional product IBI), Xaver (North Sea, Dec 2013; NWS), Gloria (NW Mediterranean, Jan 2020; MED). Wave data generated using E.U.
