European Atlantic Offshore Wave Spectral Climatology under Historical and Future Climate Scenarios

This dataset provides 3-hourly ocean wave spectral data at 1,031 fixed offshore locations along the Atlantic coast of Europe (including the British Isles) spanning three 30-year periods: historical (1985–2014), and future projections (2030-2059) under two Shared Socioeconomic Pathways (SSPs). It also includes wave parametric data (significant height, peak period, direction...).

The wave spectra were generated using the Simulating WAves Nearshore (SWAN) model, forced with high-resolution winds obtained through downscaling global climate models using the Weather Research and Forecasting (WRF) model, and open boundary conditions from simulations carried out with the WaveWatch III wave propagation model.

Each NetCDF-4 file includes eight 3-hourly spectral records per day, capturing wave energy distribution across 25 frequency bands and 36 directions for all 1,031 locations (spaced ~10 km apart, 50 km from the coast).

This spectral climatology is suitable for climate impact assessments, wave energy studies, and coastal hazard analysis.
