Parameter Name Default Value Data Type Group CASEROOT File Valid Values Description
COMP_LND dlnd char case_comp env_case.xml ['dlnd']
Name of land component
DLND_MODE NULL char run_component_dlnd env_run.xml ['CPLHIST', 'QIAN', 'GPCC', 'CLMNLDAS', 'GLC_CPLHIST', 'NULL']
DLND mode. In CPLHIST mode, land forcing data (produced by CLM) from a previous
    model run is output in coupler history files and read in by the data land model. IN GLC_CPLHIST,
    glc coupling fields are read in from a coupler history file.  In NULL mode, land forcing is
    set to zero and not utilized. The default is NULL.
DLND_CPLHIST_DOMAIN_FILE null char run_component_dlnd env_run.xml []
      Full pathname for domain file for dlnd when DLND_MODE is CPLHIST
      or GLC_CPLHIST.  NOTE: if this is set to 'null' (the default),
      then domain information is read in from the first coupler
      history file in the target stream and it is assumed that the
      first coupler stream file that is pointed to contains the domain
      information for that stream.
    
DLND_CPLHIST_DIR UNSET char run_component_dlnd env_run.xml []
directory for data
DLND_CPLHIST_CASE UNSET char run_component_dlnd env_run.xml []
case name for coupler history data mode
DLND_CPLHIST_YR_ALIGN -999 integer run_component_dlnd env_run.xml []
      Simulation year corresponding to DLND_CPLHIST_YR_START (only used
      when DLND_MODE is CPLHIST or GLC_CPLHIST). A common usage is to
      set this to RUN_STARTDATE. With this setting, the forcing in the
      first year of the run will be the forcing of year
      DLND_CPLHIST_YR_START. Another use case is to align the calendar
      of transient forcing with the model calendar. For example, setting
      DLND_CPLHIST_YR_ALIGN=DLND_CPLHIST_YR_START will lead to the
      forcing calendar being the same as the model calendar. The forcing
      for a given model year would be the forcing of the same year. This
      would be appropriate in transient runs where the model calendar is
      setup to span the same year range as the forcing data.
    
DLND_CPLHIST_YR_START -999 integer run_component_dlnd env_run.xml []
starting year to loop data over (only used when DLND_MODE is CPLHIST or GLC_CPLHIST)
DLND_CPLHIST_YR_END -999 integer run_component_dlnd env_run.xml []
ending year to loop data over (only used when DLND_MODE is CPLHIST or GLC_CPLHIST)
CLM_USRDAT_NAME UNSET char run_component_dlnd env_run.xml []
Dataset name for user-created datasets. This is used as the argument
      in Buildconf/clm.buildnml to build-namelist -clm_usr_name. An example of
      such a dataset would be 1x1pt_boulderCO_c090722. The default value is UNSET.
      This is an advanced flag and should only be used by expert users.
