Is it possible to turn off CLUBB in CESM2_1?

[linlin@email_tamu_edu]

Hi, I wonder if it is possible to turn off CLUBB in CESM2_1, in which CLUBB is a default configuration? I set do_clubb_sgs = .false. first and the corresponding eddy_scheme = 'diag_TKE', history_clubb = .false.,  macrop_scheme = 'park',  shallow_scheme = 'UW'. I got an error of "clubb_readnl:   error reading namelist". I wonder if I turn off CLUBB by setting do_clubb_sgs = .false., why the model would still read the clubb namelist? Thanks very much,Lin

Running CAM with CLUBB requires that the CLUBB code be built, and so this
decision is made at build time (i.e., via arguments to the configure
command).  That is why you are not able to turn it off with namelist
settings.  To turn off CLUBB you should use an xmlchange command to append
the argument "-noclubb_sgs" to CAM_CONFIG_OPTS.  This will automatically
revert the macrop_scheme option to 'park', the eddy_scheme to 'diag_TKE',
and the shallow_scheme to 'UW'.
