This website provides additional supplementary material including data files and figure code to aid in the reproduction of our work in the above paper. The files are provided in the table below and encompass three categories.

Primary Reconstruction Results:

1) SW_NAm_Recon_MeanT_1500-1980.dat: The spatial mean of the expected value.

2) SW_NAm_Recon_Grid_1500-1980.nc: The spatially-explitcit value of the reconstruction across the target grid.

3) SW_NAm_Recon_Grid_Uncert_1500-1980.nc: The full 1000-member uncertainty ensemble of the reconstructions.

4) SW_NAm_Recon_Grid_Uncert_1500-1980_mean_sd.nc: The mean and standard deviation of the full 1000-member uncertainty ensemble of the reconstructions.

Proxy Data:

1) WesternNAmITRDB_1400_GRL.txt: Tree-ring proxy data used in the reconstructions.

Distribution Data:

1) Proxy and pseudoproxy distribution data for the validations of the CFR and Index reconstructions. The column structures of the files are listed in the make figure file discussed below and provided in the below table.

2) Make figure file to read in the distribution data and plot the distributions in Figures 1-3 of the main text.
