This is a major concern for growing coastal communities which are already facing challenges posed by sea level rise 4, 5. As the Earth is warming, the ocean surface wind climate is changing, and thus, the waves 3. Wind waves, particularly their extreme estimates, play a crucial role in the accurate and efficient design of maritime structures 1 and as a primary element of coastal erosion and flood risk assessment studies 2. Wind waves are ocean surface waves generated as a result of the wind blowing over the ocean surface. This dataset is a valuable resource for future wind wave climate research and can find practical applications in offshore and coastal engineering projects, providing crucial insights into the uncertainties connected to wind wave climate future projections. The present ensemble outperforms a previous CMIP5-forced wind wave climate ensemble, showing improved performance across all ocean regions. Two models extend to 140 years (1961–2100) of continuous wind wave climate simulations. For each ensemble member three 30-year slices, one historical, and two future emission scenarios (SSP1-2.6 and SSP5-8.5) are available, and cover two distinct periods: 1985–20–2100. The ensemble performance is evaluated against a reference global multi-mission satellite altimeter database and the recent ECMWF IFS Cy46r1 ERA5 wave hindcast, ERA5H. The spectral wave model uses ST6 physics parametrizations and a global three-grid structure for efficient Arctic and Antarctic wave modeling.

We present a global wind wave climate model ensemble composed of eight spectral wave model simulations forced by 3-hourly surface wind speed and daily sea ice concentration from eight different CMIP6 GCMs.
