Description This dataset contains archived 3-hourly outputs from wave climate simulations at 0.5-degree global grid resolution carried out using an Irregular-Regular-Irregular (IRI) three-grid system to model the polar regions, and implemented in WaveWatch III (v6.07).
The model configuration is outlined in manuscripts:
- Meucci A., Young I. R., Hemer M., Trenham C., and Watterson I. 2023. 140 Years of Global Ocean Wind-wave Climate Derived from CMIP6 ACCESS-CM2 and EC-Earth3 GCMs. Global Trends, Regional Changes, and Future Projections. Journal of Climate, 1-56. DOI: https://doi.org/10.1175/JCLI-D-21-0929.1
- Meucci A., Young I.R., Trenham C. and Hemer M., (in prep). CMIP6-derived wave climate observation-based model ensemble.

Wave model forcing consisted of surface wind and sea-ice concentration fields from 8 CMIP6 models. The model is run with the latest observation-based source term parametrization ST6, using wind-drag coefficient "CDFAC" parameter value of 1 for all models and also 1.08 for ACCESS-CM2 and EC-EARTH3.

Archived variables, in monthly netCDF files for all simulations, include wind speed, significant wave height, second order mean wave period, peak frequency, mean and peak wave direction, wave energy, and 3 partitions of significant wave height.

In phase 1, each model simulates 140 years from 1961-2100 in 3 slices: historical (1961-2014), SSP1-2.6 (2015-2100) and SSP5-8.5 (2015-2100).
In phase 2, each model is simulated in three 30-year time slices: historical (1985-2014), SSP1-2.6 (2071-2100) and SSP5-8.5 (2071-2100).
In total, this dataset contains over 1400 simulated model years of data.

Gridded field data are provided in this collection. Directional spectra output points are available on request.
