How to ouput m_CO2_c in FWsc2010climo

[jurymark]

When I run component FWsc2010climo, I write fincl='m_CO2_c' to try to output the CO2 concentrations in different levels, but the output is all 0, how do I enable CO2 tracking?

Hi Mark, could you clarify how m_CO2_c output is set up - are you outputting averaged or instantaneous fields, what is the output frequency? Could you share your user_nl_cam configuration? Thanks!

nhtfrq = 6,6
mfilt = 1,1
fincl2 = 'U', 'V', 'T', 'O3', 'Q', 'PS', 'RHO_CLUBB', 'm_CO2_c'
pertlim=1.0e-14

That's it, no A or I (The default seems to be an instantaneous value), using xmlchange:ATM_NCPL=288, with an output frequency of 30 minutes. I tried to add tracer_cnst_specifier = 'CO2' into user_nl_cam configuration but found "Cannot find var "CO2" in file tracer_cnst_halons_3D_L70_1849-2015_CMIP6ensAvg_c180927.nc", I'm trying to expand this nc file and maybe he will work?
Thank you for your patience!

Thanks Mark! I couldn't find a default configuration where CO2 is specified in tracer_cnst_specifier namelist option so I'm not sure if that is the supported way to configure this. As FWsc2010climo is a WACCM compset I will move this to the WACCM forum for visibility. Thanks for your patience!
