 CMIP6 global climate model simulations were downloaded from the [Earth System Grid Federation](https://aims2.llnl.gov/search/cmip6). The majority of these downloads were conducted by Tongli Wang, Associate Professor at the UBC Department of Forest and Conservation Sciences.
 The 13 global climate models selected for `climr`, and best practices for ensemble analysis, are described in Mahony et al. (2022) and summarized in `vignette("climr_methods_ensembleSelection")`.
