      Determines the model run initialization type.
      This setting is only important for the initial run of a production run when the
      CONTINUE_RUN variable is set to FALSE.  After the initial run, the CONTINUE_RUN
      variable is set to TRUE, and the model restarts exactly using input
      files in a case, date, and bit-for-bit continuous fashion.
      Default: startup.
      -- In a startup run (the default), all components are initialized
      using baseline states.  These baseline states are set independently by
      each component and can include the use of restart files, initial
      files, external observed data files, or internal initialization (i.e.,
      a cold start). In a startup run, the coupler sends the start date to
      the components at initialization. In addition, the coupler does not
      need an input data file.  In a startup initialization, the ocean model
      does not start until the second ocean coupling (normally the second
      day).
      -- In a branch run, all components are initialized using a consistent
      set of restart files from a previous run (determined by the
      RUN_REFCASE and RUN_REFDATE variables in env_run.xml).  The case name
      is generally changed for a branch run, although it does not have to
      be. In a branch run, setting RUN_STARTDATE is ignored because the
      model components obtain the start date from their restart datasets.
      Therefore, the start date cannot be changed for a branch run. This is
      the same mechanism that is used for performing a restart run (where
      CONTINUE_RUN is set to TRUE in the env_run.xml) Branch runs are
      typically used when sensitivity or parameter studies are required, or
      when settings for history file output streams need to be modified
      while still maintaining bit-for-bit reproducibility. Under this
      scenario, the new case is able to produce an exact bit-for-bit restart
      in the same manner as a continuation run IF no source code or
      component namelist inputs are modified. All models use restart files
      to perform this type of run.  RUN_REFCASE and RUN_REFDATE are required
      for branch runs.
      To set up a branch run, locate the restart tar file or restart
      directory for RUN_REFCASE and RUN_REFDATE from a previous run, then
      place those files in the RUNDIR directory.
      --- In a hybrid run the model is initialized as a startup, BUT uses
      initialization datasets FROM A PREVIOUS case.  This
      is somewhat analogous to a branch run with relaxed restart
      constraints.  A hybrid run allows users to bring together combinations
      of initial/restart files from a previous case (specified by
      RUN_REFCASE) at a given model output date (specified by
      RUN_REFDATE). Unlike a branch run, the starting date of a hybrid run
      (specified by RUN_STARTDATE) can be modified relative to the reference
      case. In a hybrid run, the model does not continue in a bit-for-bit
      fashion with respect to the reference case. The resulting climate,
      however, should be continuous provided that no model source code or
      namelists are changed in the hybrid run.  In a hybrid initialization,
      the ocean model does not start until the second ocean coupling
      (normally the second day), and the coupler does a cold start without
      a restart file.

    (executable is $EXEROOT/$MODEL.exe, component libraries are in $EXEROOT/lib)
    This is where the model builds its executable and by default runs the executable.
    Note that EXEROOT needs to have enough disk space for the experimental configuration
    requirements. As an example, a model run can produce more than a terabyte of
    data during a 100-year run, so you should set EXEROOT to scratch or
    tmp space and frequently back up the data to a long term archiving storage device
    For a supported machine, EXEROOT is set in $CIMEROOT/machines/config_machines.xml.
    For a userdefined machine, EXEROOT must explicitly be set it in env_build.xml.</desc>
