 sdesc="Run initialization type"
 ldesc="
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.
--- A hybrid run indicates that the model is initialized more like 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."

DICE is a combination of a data model and a prognostic model. 
The data functionality reads in ice coverage. The prognostic functionality 
calculates the ice/atmosphere and ice/ocean fluxes. DICE receives the same 
atmospheric input from the coupler as the active CICE model (i.e., atmospheric 
states, shortwave fluxes, and ocean ice melt flux). DICE acts very similarly
to CICE running in prescribed mode.) Currently, this component is only
used to drive POP2 in C compsets.
If DICE_MODE is set to ssmi or ssmi_iaf, it is a prognostic mode. 
It requires data be sent to the ice model. 
Ice fraction (extent) data is read from an input stream,
atmosphere state variables are received from the coupler, and then
an atmosphere-ice surface flux is computed and sent to the
coupler. Normally the ice fraction data is found in the same data files 
that provide SST data to the data ocean model. They are normally found 
in the same file because the SST and ice fraction data are derived from the
same observational data sets and are consistent with each other."

The data ocean component (DOCN) always returns SSTs to the
driver. The atmosphere/ocean fluxes are computed in the
coupler. Therefore, the data ocean model does not compute fluxes like
the data ice model. DOCN has two distinct modes of operation. It can
arun as a pure data model, reading in ocean SSTs (normally
climatological) from input datasets, performing time/spatial
interpolations, and passing these to the coupler. Alternatively,
DOCN can compute updated SSTs by running as a slab ocean model where
bottom ocean heat flux convergence and boundary layer depths are read
in and used with the atmosphere/ocean and ice/ocean fluxes obtained
from the driver.
--- A setting of prescribed assumes the only field in the input stream is SST.
It also assumes the SST is in Celsius and must be converted to Kelvin.
All other fields are set to zero except for ocean salinity, which
is set to a constant reference salinity value.

to the data ocean model. They are normally found in the same file
because the SST and ice fraction data are derived from the same
observational data sets and are consistent with each other.
--- A setting of som (slab ocean model) mode is a prognostic mode.  This mode
computes a prognostic sea surface temperature and a freeze/melt
potential (surface Q-flux) used by the sea ice model.  This
calculation requires an external SOM forcing data file that includes
ocean mixed layer depths and bottom-of-the-slab Q-fluxes.
Scientifically appropriate bottom-of-the-slab Q-fluxes are normally
ocean resolution dependent and are derived from the ocean model output
of a fully coupled CCSM run.  Note that while this mode runs out of
the box, the default SOM forcing file is not scientifically
appropriate and is provided for testing and development purposes only.
Users must create scientifically appropriate data for their particular
application.  A tool is available to derive valid SOM forcing. 
Default is prescribed."
