    "title": "European Atlantic Wave Data under Historical and Future Climate Scenarios (EAWAVES-CLIM)",
    "abstract": "This dataset provides 3-hourly ocean wave data for the European Atlantic domain spanning three 30-year periods: a historical simulation (1985–2014) and future projections (2030–2059) under two Shared Socioeconomic Pathways (SSP2-4.5 and SSP5-8.5). It includes directional wave spectral data at 1,031 fixed offshore locations along the Atlantic coast of Europe, as well as gridded wave parameters covering the full North Atlantic simulation domain.\r\n\r\nThe wave data were generated using the Simulating WAves Nearshore (SWAN) model, forced with high-resolution winds obtained through dynamical downscaling of global climate models using the Weather Research and Forecasting (WRF) model, and open boundary conditions derived from WaveWatch III simulations.\r\n\r\nThe spectral component consists of NetCDF-4 files describing wave energy distribution across 25 frequency bands and 36 directions at offshore locations spaced approximately 10 km alongshore and 50 km from the coast.",

    "dataLineage": "This dataset was generated using a multi-stage modeling workflow. First, atmospheric variables from multiple CMIP6 climate models were bias-corrected and dynamically downscaled using the WRF model to produce high-resolution wind fields. These winds were then used to drive WaveWatch III simulations across the North Atlantic to provide offshore boundary conditions. Finally, the SWAN wave model was run at high resolution along the European Atlantic coast using WRF winds and WaveWatch III boundaries to compute detailed 3-hourly wave spectra at 1,031 offshore points. The entire workflow was repeated for three periods: historical (1985–2014) and future scenarios SSP2-4.5 and SSP5-8.5 (2030–2059). The output files were processed, verified, and stored in NetCDF-4 format following CF conventions before being transferred to the CEDA data centre.",
