Data for "A New Year-Round Weather Regime Classification for North America"

This dataset supports the work presented in "A New Year-Round Weather Regime Classification for North America" by Lee et al. (2023), published in Journal of Climate: https://doi.org/10.1175/JCLI-D-23-0214.1 

The dataset includes the Z500 climatology and anomalies, the EOFs/PCs, and the parameters required to attribute each day to a regime, alongside the regimes as assigned over 1979-2022 (time series in netCDF and csv formats). In addition, we also supply the standardized projection of each day onto the cluster-mean normalized Z500 anomalies for each regime, termed the Weather Regime Index (WRI).
