How to switch off a namelist variable

[James King]

Hi all,

I'm trying to build a transient run based on an existing non-transient run I made previously. The problem I am having is trying to turn off 'ext_frc_cycle_yr', 'srf_emis_cycle_yr', etc. The model doesn't run because these values are fixed at 2010, even though I have not set them in user_nl_cam and I have 'ext_frc_type' etc. set to 'INTERP_MISSING_YEARS'. Following other users on these forums, I have tried:

ext_frc_cycle_yr =
ext_frc_cycle_yr = " (quotation mark)
ext_frc_cycle_yr = '' (two apostrophes)
ext_frc_cycle)yr - ' ' (two apostrophes with a space in the middle)

but to no avail, as when I run ./check_case I get some variation on

ERROR: Invalid namelist variable in '-infile' /glade/work/jamesking/cases/SSP3_transient_test_00/Buildconf/camconf/namelist.
ERROR: in _validate_pair (package Build::NamelistDefinition): Variable name ext_frc_cycle_yr has an input value of type string,
' '
but is defined as type integer in /glade/work/jamesking/CESM2_2_0/components/cam/bld/namelist_files/namelist_definition.xml

How do I turn these settings off? Model version is CESM2.2.0 and I'm working on Cheyenne.

Thanks,

James

If you want to cycle over a single, I think you should set:

ext_frc_cycle_yr               = 2010
ext_frc_type           = 'CYCLICAL'

instead of

ext_frc_type           =  'INTERP_MISSING_YEARS'

Hi Cecile,

I don't want to cycle over a single year, that's the problem! I want to do a transient run but can't work out how to remove the setting 'ext_frc_cycle_yr' which appears in my atm_in even though I haven't set it in user_nl_cam. Trying previous forum suggestions for turning namelist settings off hasn't worked.

Cheers,

James
