1 Native means every model on their native grid they were run on

2 CMIP-ng: Next Generation archives were maintained by Reto’s group (Jan Sedlacek/Lukas Brunner) Ruth Lorenz / C2SM took over cmip6-ng in 2022. contact: cmip6-archive@env.ethz.ch, documentation: https://doi.org/10.5281/zenodo.3734128
