. . . . "Wave conditions at storm landfall were reconstructed using the CMEMS regional wave reanalysis for each basin: IBI (Xynthia), NWSHELF (Xaver), and MEDSEA (Gloria). These higher-resolution, basin-specific models (1.5–4 km) were compared with the global WAVERYS reanalysis to assess the impact of model choice. Both approaches are operational products validated against in-situ buoy observations through CMEMS quality assessments." . "Wave conditions at storm landfall were reconstructed using the Copernicus Marine WAVERYS global wave reanalysis (GLOBAL_MULTIYEAR_WAV_001_032). WAVERYS is based on the MFWAM spectral wave model, forced by ERA5 winds and constrained by altimeter and Sentinel-1 SAR observations, on a 0.2° global grid at 3-hourly resolution. The methodological choice was to derive wave fields from a globally consistent model and aggregate results to each site polygon." . "Difference in biodiversity exposure attribution between global and regional wave products. Measured as the biodiversity-weighted fraction of Natura 2000 marine sites where storm-time significant wave height differs by more than a threshold X (~0.4 m), derived from CMEMS validation RMSEs. Site weights are log1p(Annex I habitats + Annex II species). Results are reported per storm and across all storms, with fixed (0.5 m) and relative (10% of peak Hs) sensitivity analyses." . "Coastal Natura 2000 marine sites (SACs and SPAs with marine area > 0) designated under the EU Habitats and Birds Directives. The population covers three European basins affected by the storms shown: the French Atlantic coast (Bay of Biscay, Pertuis Charentais), the southern North Sea and German Bight (Wadden Sea), and the north-western Mediterranean (Catalan coast and Ebro Delta)." . . . . . "At coastal Natura 2000 marine sites in the landfall path of three European storms (Xynthia 2010, Xaver 2013, Gloria 2020), does coupled wave hindcasting using the WAVERYS global ocean wave reanalysis (Copernicus Marine, MFWAM, 0.2 degrees) produce a different biodiversity exposure attribution — measured as the fraction of biodiversity-weighted sites where the storm-window peak significant-wave-height delta exceeds the joint observational noise floor of approximately 0.4 metres — than coupled wave hindcasting using the matched regional CMEMS wave reanalysis (Iberia-Biscay-Ireland at 3 km, North-West Shelf at 1.5 km, Mediterranean at 4 km)?" . . .
