<desc>Logical to archive all interim restart files, not just those at eor
If TRUE, perform short term archiving on all interim restart files,
not just those at the end of the run. By default, this value is TRUE.
The restart files are saved under the specific component directory
($DOUT_S_ROOT/$CASE/$COMPONENT/rest rather than the top-level $DOUT_S_ROOT/$CASE/rest directory).
Interim restart files are created using the REST_N and REST_OPTION variables.
This is for expert users ONLY and requires expert knowledge.
We will not document this further in this guide.</desc>

<desc>
Coupler sequencing option. This is used to set the driver namelist variable cpl_seq_option.
CESM1_ORIG is the cesm1.1 implementation.
CESM1_MOD includes a cesm1.3 mod that swaps ocean merging and atm/ocn flux
computation.
RASM_OPTION1 runs prep ocean before the ocean coupling reducing
most of the lags and field inconsistency but still allowing the ocean to run
concurrently with the ice and atmosphere.
RASM_OPTION2 is similar to RASM_OPTION1
but sequences the ice model, prep ocean and ocean model in that order. The
ocean model loses some of the concurrency with the ice model.
CESM1_ORIG_TIGHT and CESM1_MOD_TIGHT are consistent with the old variables
ocean_tight_coupling = true in the driver. That namelist is gone and the
cpl_seq_option flags take it's place.
TIGHT coupling makes no sense with the OPTION5 and OPTION6 flags.

<desc>Activates additional CO2-related fields to be exchanged between components. Possible values are:
CO2A: sets the driver namelist variable flds_co2a = .true.; this adds
prognostic CO2 and diagnostic CO2 at the lowest model level to be sent from
the atmosphere to the land and ocean.
CO2A_OI: sets the driver namelist variable flds_co2a = .true.; this adds
prognostic CO2 and diagnostic CO2 at the lowest model level to be sent from
the atmosphere to the land and ocean. Also sets the driver namelist variable
flds_bgc_oi = .true.; this turns on the transfer of bgc fields between the
ocean and seaice components via the coupler.
CO2B: sets the driver namelist variable flds_co2b = .true.; this adds
prognostic CO2 and diagnostic CO2 at the lowest model level to be sent from
the atmosphere just to the land, and the surface upward flux of CO2 to be
sent from the land back to the atmosphere
CO2C: sets the driver namelist variable flds_co2c = .true.; this adds
prognostic CO2 and diagnostic CO2 at the lowest model level to be sent from
the atmosphere to the land and ocean, and the surface upward flux of CO2
to be sent from the land and the open ocean back to the atmosphere.
CO2_DMSA: sets the driver namelist variable flds_co2_dmsa = .true.
The namelist variables flds_co2a, flds_co2b, flds_co2c and flds_co2_dmsa are
in the namelist group cpl_flds_inparm.

<desc>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).

Only used for compsets with DATM and POP (currently C, G and J):
If true, compute albedos to work with daily avg SW down
If false (default), albedos are computed with the assumption that downward
solar radiation from the atm component has a diurnal cycle and zenith-angle
dependence. This is normally the case when using an active atm component
If true, albedos are computed with the assumption that downward
solar radiation from the atm component is a daily average quantity and
does not have a zenith-angle dependence. This is often the case when
using a data atm component. Only used for compsets with DATM and POP (currently C, G and J).
NOTE: This should really depend on the datm forcing and not the compset per se.
So, for example, whether it is set in a J compset should depend on
what datm forcing is used.

Only used for compsets with DATM and POP (currently C, G and J):
If ocn, ocn provides EP balance factor for precipitation.
Provides EP balance factor for precip for POP. A factor computed by
POP is applied to precipitation so that precipitation balances
evaporation and ocn global salinity does not drift. This is intended
for use when coupling POP to a DATM. Only used for C, G and J compsets.
