Seeking information on the default co2 forcing data used in CTSM

[jiamengl]

What version of the code are you using?
ctsm5.1.dev159

Describe your problem or question:
May I get information on the default CO2 forcing data that is used in CTSM? The directory for the data is: /glade/p/cesmdata/cseg/inputdata/atm/datm7/CO2/fco2_datm_global_simyr_1750-2014_CMIP6_c180929.nc

From the attribute of this dataset seems like it is regenerated from an original dataset /gpfs/fs1/p/acom/acom-climate/cesm2/inputdata/atm/waccm/lb/LBC_1750-2015_CMIP6_GlobAnnAvg_c180905.nc but this file is no longer in this directory. I am wondering how this forcing CO2 is generated and if there is any reference to cite?

Since the dataset relates to chemistry, I will move this thread accordingly.

...but also the file is labeled CMIP6, so it's likely documented somewhere in the CMIP6 literature.

Thanks for the reply. I did find a reference about CMIP6 CO2: Meinshausen, M., Vogel, E., Nauels, A., Lorbacher, K., Meinshausen, N., Etheridge, D. M., Fraser, P. J., Montzka, S. A., Rayner, P. J., Trudinger, C. M., Krummel, P. B., Beyerle, U., Canadell, J. G., Daniel, J. S., Enting, I. G., Law, R. M., Lunder, C. R., O'Doherty, S., Prinn, R. G., Reimann, S., Rubino, M., Velders, G. J. M., Vollmer, M. K., Wang, R. H. J., and Weiss, R.: Historical greenhouse gas concentrations for climate modelling (CMIP6), Geosci. Model Dev., 10, 2057–2116, GMD - Historical greenhouse gas concentrations for climate modelling (CMIP6), 2017.
I am just not sure if this is the correct reference to cite
