CMIP6 global wind-wave 21st century climate projections phase 1

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 three-grid system to model the polar regions, and implemented in WaveWatch III (v6.07). 

The model configuration is outlined in manuscripts: 
Meucci, Young, Hemer, and Trenham, 2021. CMIP6 derived ocean wind-wave climate across two centuries Part I and Part II. Submitted to JCLIM 

Wave model forcing consisted of surface wind and sea-ice concentration fields from two CMIP6 models. 
The model is run with the latest observation-based source term parametrization ST6, using two different values of the wind-drag coefficient "CDFAC" parameter: 1 and 1.08. 
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 total, this dataset contains over 700 simulated model years of data. 
Gridded field data are provided in this collection. Directional spectra output points are available on request.

Lineage: The wave model is forced with 3-hourly surface winds and linearly interpolated daily sea-ice concentration fields taken from the designated forcing CMIP6 General Circulation Models. Output is produced on the IRI grid as well as at point locations every 10 degrees globally and in higher resolution rings around Australia as a whole, and the SE corner (Vic-Tas).

The computational resources were provided by the NCI through an NCMAS computational time grant. The initial tests were undertaken using the LIEF HPC-GPGPU Facility hosted at the University of Melbourne. This Facility was established with the assistance of LIEF Grant LE170100200. This data collection is supported by the Australian Government through the National Environmental Science Programme's Climate Systems Hub.
