      WARNING: CAM is tuned to the default value of this variable. Because it affects
      so many different parameterizations, changes to this variable may require a

      orbital model setting.  this sets how the orbital mode will be
      configured.
      "fixed_year" uses the orb_iyear and other orb inputs are ignored.  In
      this mode, the orbital parameters are constant and based on the year.
      "variable_year" uses the orb_iyear and orb_iyear_align.  In this mode,
      the orbital parameters vary as the model year advances and the model
      year orb_iyear_align has the equivalent orbital year of orb_iyear.
      "fixed_parameters" uses the orb_eccen, orb_mvelp, and orb_obliq to set
      the orbital parameters which then remain constant through the model
      integration. [fixed_year, variable_year, fixed_parameters]  (default: 'fixed_year'.)

    <desc>
      Whether to renormalize the surface mass balance (smb) sent from lnd to glc so that the
      global integral on the glc grid agrees with the global integral on the lnd grid.

      Unlike most fluxes, smb is remapped with bilinear rather than conservative mapping weights,
      so this option is needed for conservation. However, conservation is not required in many
      cases, since we often run glc as a diagnostic (one-way-coupled) component.

      Allowable values are:
      'on': always do this renormalization
      'off': never do this renormalization (see WARNING below)
      'on_if_glc_coupled_fluxes': Determine at runtime whether to do this renormalization.
         Does the renormalization if we're running a two-way-coupled glc that sends fluxes
         to other components (which is the case where we need conservation).
         Does NOT do the renormalization if we're running a one-way-coupled glc, or if
         we're running a glc-only compset (T compsets).
         (In these cases, conservation is not important.)

      Only used if running with a prognostic GLC component.

      WARNING: Setting this to 'off' will break conservation when running with an
      evolving, two-way-coupled glc.

      Period at which coupler averages fields sent to GLC.
      This supports doing the averaging to GLC less frequently than GLC is called
      (i.e., separating the averaging frequency from the calling frequency).
      This is useful because there are benefits to only averaging the GLC inputs
      as frequently as they are really needed (yearly for CISM), but GLC needs to
      still be called more frequently than that in order to support mid-year restarts.

      Setting glc_avg_period to 'glc_coupling_period' means that the averaging is
      done exactly when the GLC is called (governed by GLC_NCPL).
