A biogeochemically coupled version of the 1pctCO2-cdr simulation proposed for CMIP6 CDRMIP has been run by 5 CMIP6 ESMs and is archived here. Model names and the corresponding references are listed in Table 1 of the accompanying README file. The model output has been converted to comply with CMIP6 standards (“cmorized”). Model names, variable names, variant labels, and so forth are the same as for data downloaded from the ESGF website (e.g., https://esgf-data.dkrz.de/search/cmip6-dkrz/). One zipped tar-archive per model is provided (where the file name is modelname.tar.gz). The directory structure of the archive (when extracted) follows CMIP6/ESGF standards.
