We provide data used to obtain the results of our study, comprising: 1) wave climate statistics for Hs, Tp, and θp for each model and each period studied; 2) two sets of annual maxima distribution for each model, which were bias-corrected assuming that the set of extreme events follows either a Gumbel distribution or a GEV distribution. For more details on the methods, please refer to Toomey et al., 2024 (DOI).

The first part of the dataset can be found in the folder Mean_and_Q95_statistics_by_model. Files are separeted into two categories (two folders), correpsonding to models with atmospherics forcing time frequency of 3hr and 6hr. Further, there are 3 folders for each wave variable. For every statistical indicator, there is a file .nc for each model nad each period (historical, rcp85_mid, rcp 85_end), with name following: "Model_ raw_period_Var_Yearinit_Yearend_statistics", e.g. "RCA4-NorESM1-M_raw_historical_hs_1979_2005_seasonalquantiles.nc".
For hs and tp, there are 4 types of files
a) Model_raw_period_Var_Yearinit_Yearendseasonalquantiles.nc, quantiles in [0.1,0.5,0.9,0.95,0.99]
b) Model_raw_period_Var_Yearinit_Yearendseasonalquantiles_interannual_std.nc
c) Model_raw_period_Var_Yearinit_Yearendseasonalmean.nc
d) Model_raw_period_Var_Yearinit_Yearendseasonalmean_interannual_std.nc
For dp:
a) Model_raw_period_dp_Yearinit_Yearendseasonal_mean_q95hs.nc
b) Model_raw_period_dp_Yearinit_Yearend_seasonalmean_q95hs_interannual_std.nc

The second part of dataset consists in the biascorrected annual maximas assuming that the set of extreme events follows either a Gumbel distribution or a GEV distribution. .nc files can be found in the folder Bias_corrected_annual_maxima_by_model for both 3hr and 6hr models, for both bias correction methods employed (assuming Gumbel and GEV distributions):
a) Model_raw_period_hs_Yearinit_Yearend_annual_maxima_CDF_GEV_bias_corrected.nc
b) Model_raw_period_hs_Yearinit_Yearend_annual_maxima_CDF_GUMBEL_bias_corrected.nc
These distributions of bias corrected annual maxima bias are used in the study to compute return levels.
