Description:
Parameter values for
kc_nonmycandkn_nonmycswitched in CLM5 & CTSM5.1 .@ecaas noticed low mycorrhizal N uptake rates in CLM5.1 simulations and worked with @rosiealice and FUN developers to determine that parameter values for non-mycorrhizal N uptake costs (
kc_nonmycandkn_nonmyc) in FUN were switched CTSM Issue #2120, see also discussion #2098.@linniahawkins did some tests with the sparse grid to quickly evaluate the global impact of this bug and found lower steady state C pools and fluxes, but similar behavior in transient simulations. This simulation is intended to more fully evaluate impacts of fixing the parameter bug in global CLM land only simulations. Given differences in the code base, it may be necessary to create a new parameter file for the main development branch of the model.
Corrected values for these parameter from @ecaas are below

user_nl_ changes:
Same as #1 plus new paramfile:
paramfile = '/glade/u/home/slevis/cases_LMWG_dev/issue8/inputs/ctsm51_params.LMWG_dev8.c230911.nc'Also from #1 I copied CaseDocs/datm.streams.xml to this case rather than modifying the /cdeps directory, which is what Keith's setup does.
SourceMods:
Same as #1.
