Use the CASEROOT tools xmlquery to query these variables and xmlchange to change their values.

Parameter Name Default Value Data Type Group CASEROOT File Valid Values Description
COMP_GLC dglc char case_comp env_case.xml ['dglc'] 
Name of land component
DGLC_MODE noevolve char run_component_dglc env_run.xml ['noevolve'] 
      NOEVOLVE mode is used in CESM as follows.
      In typical runs, CISM is not evolving; CLM computes the surface mass
      balance (SMB) and sends it to CISM, but CISM’s ice sheet geometry
      remains fixed over the course of the run. In these runs, CISM serves
      two roles in the system:
GLC_USE_GREENLAND FALSE logical run_component_dglc env_run.xml None 
Whether to include the Greenland Ice Sheet in this DGLC simulation
    This should generally be set at create_newcase time (via the compset). In principle it
    can be changed later, but great care is needed to change a number of other variables
    to be consistent (GLC_GRID, GLC_DOMAIN_MESH and possibly others).
GLC_USE_ANTARCTICA FALSE logical run_component_dglc env_run.xml None 
Whether to include the Antarctica Ice Sheet in this DGLC simulation
    This should generally be set at create_newcase time (via the compset). In principle it
    can be changed later, but great care is needed to change a number of other variables
    to be consistent (GLC_GRID, GLC_DOMAIN_MESH and possibly others).
DGLC_SKIP_RESTART_READ FALSE logical run_component_dglc env_run.xml ['TRUE', 'FALSE'] 
 If set to true, than dglc restarts will not be read on a continuation run.
