Model Version: CESM2.0
HTML created on: 2017-06-21
Description
The CASEROOT scripts read the XML settings in the env_run.xml file in order to
determine case run specific settings.
Interface Tools
CESM2.0 supports multiple run groups.
The xmlquery
and xmlchange script tools
accept the --subgroup command line argument to define one of the run groups.
Changes to these settings may be made prior to calling case.submit.

File Description Header <header>
These variables MAY BE CHANGED ANYTIME during a run.
Additional machine speific variables that can be changed
during a run are contained in the env_mach_specific file
Note1: users SHOULD NOT modify BUILD_COMPETE in env_build.xml
this is done automatically by the scripts.

Run Group Settings <group id="run_begin_stop_restart"> :
Description <desc> :
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.

Description <desc> :

If any component 'pauses' (see PAUSE_OPTION, PAUSE_N and
PAUSE_COMPONENT_LIST XML variables), the ESP component (if
present) will be run to process the component 'pause' (restart)
files and set any required 'resume' signals.

Attributes :
id = CONTINUE_RUN
value = TRUE
Data Type <type> : logical
Valid Values <valid_values> : TRUE,FALSE
Description <desc> :
A setting of TRUE implies a continuation run
When you first begin a branch, hybrid or startup run, CONTINUE_RUN
must be set to FALSE. When you successfully run and get a restart
file, you will need to change CONTINUE_RUN to TRUE for the remainder
of your run. This variable determines if the run is a restart run.
Set to FALSE when initializing a startup, branch or hybrid case.
Set to TRUE when continuing a run.
Entry ID/Value Definitions <entry> :
Attributes :
id = RESUBMIT
value = 0
Data Type <type> : integer
Description <desc> : If RESUBMIT is greater than 0, then case will automatically resubmit
Enables the model to automatically resubmit a new run. To get
multiple runs, set RESUBMIT greater than 0, then RESUBMIT will be
decremented and the case will be resubmitted. The case will stop automatically
resubmitting when the RESUBMIT value reaches 0.
Long runs can easily outstrip supercomputer queue time limits. For
this reason, a case is usually run as a series of jobs, each
restarting where the previous finished.
Entry ID/Value Definitions <entry> :

TRUE. This flag might be used in conjunction with COMP_RUN_BARRIERS for
timing tests.

Data Type <type> : logical
Valid Values <valid_values> : TRUE,FALSE
Description <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 FALSE.
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.

Attributes :

value = 1
Data Type <type> : integer
Description <desc> : Number of glc coupling intervals per NCPL_BASE_PERIOD.
Description <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).
IMPORTANT: In order to restart mid-year when running with CISM, you MUST specify GLC_AVG_PERIOD = 'yearly'.
If using GLC_AVG_PERIOD = 'glc_coupling_period' with CISM, you can only restart on year boundaries.

Description <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.

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.
