glc_renormalize_smb seq_infodata_inparm control char ['on', 'off', 'on_if_glc_coupled_fluxes']
      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.

vect_map seq_infodata_inparm mapping char ['none', 'npfix', 'cart3d', 'cart3d_diag', 'cart3d_uvw', 'cart3d_uvw_diag']
      vect_map
      turns on the vector mapping option for u and v vector mapping between
      atm and ocean grids in the coupler.  the options are none, npfix,
      cart3d, cart3d_diag, cart3d_uvw, and cart3d_uvw_diag.  the none option
      results in scalar mapping independently for the u and v field which
      tends to generate large errors near the poles.  npfix is the
      traditional option where the vectors are corrected on the ocean grid
      north of the last latitude line of the atmosphere grid.  the cart3d
      options convert the east (u) and north (v) vectors to 3d (x,y,z)
      triplets, and maps those fields before converting back to the east (u)
      and north (v) directions.  the cart3d ignores the resuling "w"
      velocity.  the cart3d_uvw calculates the resulting u and v vectors by
      preserving the total "u,v,w" speed and the angle of the (u,v) vector.
      the _diag options just add diagnotics to the log file about the vector
      mapping.

      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

      array cplflds_customs. The user specified new fields must follow the
      above naming convention.
      As an example, say you want to add a new state 'foo' that is passed
      from the land to the atm - you would do this as follows
      &seq_flds_user
      cplflds_custom = 'Sa_foo->a2x', 'Sa_foo->x2a'

      This would add the field 'Sa_foo' to the character strings defining the

glc_avg_period seq_timemgr_inparm time char ['glc_coupling_period', 'yearly']

      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.
