This file is to provide information for the manuscript **CMIP6 models agree on similar carbon cycle feedbacks between enhancing terrestrial and marine carbon sinks** submitted to Environmental Research Letters by Wey et al. In this study, we utilize the C4MIP *esm-ssp585*, LUMIP *esm-ssp585-ssp1126Lu* and CDRMIP *esm-ssp585-ocn-alk* experiments. In total, eight models are analyzed. For seven of them, the *esm-ssp585* and *esm-ssp585-ssp1126Lu* experiments are analyzed, and for four of them, the *esm-ssp585* and *esm-ssp585-ocn-alk* experiments are analyzed. All experiments of ACCESS-ESM1-5, CanESM5, CESM2, MIROC-ES2L, UKESM1-0-LL, and NorESM2-LM were downloaded from the ESGF website with the DOI listed below. | Model | Experiment | DOI | | ------------- | ------------------- | ------------------------- | | ACCESS-ESM1-5 | esm-ssp585 | 10.22033/ESGF/CMIP6.4252 | | ACCESS-ESM1-5 | esm-ssp585-ssp126Lu | 10.22033/ESGF/CMIP6.15743 | | CanESM5 | esm-ssp585 | 10.22033/ESGF/CMIP6.3587 | | CanESM5 | esm-ssp585-ssp126Lu | 10.22033/ESGF/CMIP6.3588 | | CESM2 | esm-ssp585 | 10.22033/ESGF/CMIP6.7582 | | CESM2 | esm-ssp585-ssp126Lu | 10.22033/ESGF/CMIP6.7585 | | MIROC-ES2L | esm-ssp585 | 10.22033/ESGF/CMIP6.5526 | | MIROC-ES2L | esm-ssp585-ssp126Lu | 10.22033/ESGF/CMIP6.5529 | | MPI-ESM1-2-LR | esm-ssp585 | 10.22033/ESGF/CMIP6.6558 | | MPI-ESM1-2-LR | esm-ssp585-ssp126Lu | 10.22033/ESGF/CMIP6.6561 | | NorESM2-LM | esm-ssp585 | 10.22033/ESGF/CMIP6.13748 | | NorESM2-LM | esm-ssp585-ocn-alk | 10.22033/ESGF/CMIP6.13749 | | UKESM1-0-LL | esm-ssp585 | 10.22033/ESGF/CMIP6.5969 | | UKESM1-0-LL | esm-ssp585-ssp126Lu | 10.22033/ESGF/CMIP6.5973 | | UKESM1-0-LL | esm-ssp585-ocn-alk | 10.22033/ESGF/CMIP6.12205 | For FOCI, the simulations were conducted for this study and Chien et al. (2022). For MPI-ESM1-2-LR, some of the simulations were downloaded from the ESGF website, and the rest are conducted for this study.
