CESM2.1.2 DLND2.1 CASEROOT Variable Definitions

Name of land component

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.

      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.
    

directory for coupler history data mode (only used for CPLHIST mode)

case name for coupler history data mode (only used for CPLHIST mode)

      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.
