| Parameter Name | Default Value | Data Type | Group | CASEROOT File | Valid Values | Description |
|---|---|---|---|---|---|---|
| COMP_OCN | pop | char | case_comp | env_case.xml | pop | Name of ocean component |
| OCN_PE_CHANGE_REQUIRES_REBUILD | True | logical | case_comp | env_case.xml | TRUE,FALSE | This component requires a clean build if the pelayout changes, if this variable is
not defined for a component it is assumed FALSE
|
| OCN_CHL_TYPE | diagnostic | char | run_component_pop | env_run.xml | diagnostic,prognostic |
Determines provenance of surface Chl for radiative penetration,
computations. This option is used in the POP ecosystem model.
The default is diagnostic.
|
| OCN_TAVG_TRACER_BUDGET | False | logical | run_component_pop | env_run.xml | TRUE,FALSE | tavg output control for tracer-budget terms |
| OCN_TAVG_HIFREQ | False | logical | run_component_pop | env_run.xml | TRUE,FALSE | tavg output control for high-frequency output |
| OCN_ONEDIM | False | logical | run_component_pop | env_run.xml | TRUE,FALSE | TRUE turns off all horizontal motion in POP (single column) |
| OCN_TRACER_MODULES | iage | char | build_component_pop | env_build.xml | None | Optional ocean tracers. Valid values are Any combination of: iage cfc ecosys |
| OCN_TRACER_MODULES_OPT | char | build_component_pop | env_build.xml | None | Optional ocean tracers option (keyword=value pairs) |
|
| OCN_COUPLING | full | char | build_pop | env_build.xml | full,partial | Determine surface freshwater and heat forcing settings.
The full option yields settings that are appropriate for coupling to an
active atmospheric model (e.g., a B-type compset). The partial option yields
settings that are appropriate for coupling to a data atmospheric model
(e.g., a C or G-type compset). The create_newcase command selects the
appropriate setting for this variable based on the specified compset.
Users should NOT EDIT this setting. |
| OCN_TRANSIENT | unset | char | run_component_pop | env_run.xml | unset,CORE2,1850-2000,rcp4.5,rcp8.5 | Determine settings for transient forcing datasets (e.g., atmospheric pCFC
concentrations). The create_newcase command selects the appropriate setting for this
variable based on the specified compset. This option is used in the POP ecosystem model.
Users should NOT EDIT this setting. |
| OCN_ICE_FORCING | active | char | run_component_pop | env_run.xml | active,inactive | Determine under-ice forcing settings.
The active option yields settings that are appropriate for coupling to an active ice model
(e.g., a B or G-type compset). The inactive option yields settings that are appropriate for
coupling to a data ice model (e.g., a C-type compset). The create_newcase command
selects the appropriate setting for this variable based on the specified compset.
Users should NOT EDIT this setting. |
| OCN_CO2_TYPE | constant | char | run_component_pop | env_run.xml | constant,prognostic,diagnostic,box_atm_co2 | Determines provenance of atmospheric CO2 for gas flux computation.
This option is used in the POP ecosystem model.
The default is constant. |
| POP_TAVG_R8 | False | logical | build_component_pop | env_build.xml | TRUE,FALSE | If TRUE then time-averaged history files from POP will contain double precision output |
| POP_AUTO_DECOMP | True | logical | build_component_pop | env_build.xml | TRUE,FALSE | if FALSE, user must set the POP decomp, otherwise cesm_setup script sets it |
| POP_BLCKX | 0 | integer | build_component_pop | env_build.xml | None | Size of pop block in first horiz dimension (do not edit if POP_AUTO_DECOMP is TRUE) |
| POP_BLCKY | 0 | integer | build_component_pop | env_build.xml | None | Size of pop block in second horiz dimension (do not edit if POP_AUTO_DECOMP is TRUE) |
| POP_NX_BLOCKS | 0 | integer | build_component_pop | env_build.xml | None | Number of pop blocks in first horiz dimension (do not edit if POP_AUTO_DECOMP is TRUE) |
| POP_NY_BLOCKS | 0 | integer | build_component_pop | env_build.xml | None | Number of pop blocks in second horiz dimension (do not edit if POP_AUTO_DECOMP is TRUE) |
| POP_MXBLCKS | 0 | integer | build_component_pop | env_build.xml | None | Max number of pop blocks per processor (do not edit if POP_AUTO_DECOMP is TRUE |
| POP_DECOMPTYPE | 0 | char | build_component_pop | env_build.xml | None | pop block distribution type (do not edit if POP_AUTO_DECOMP is TRUE) |
| POP_CPPDEFS | UNSET | char | build_component_pop | env_build.xml | None | POP cpp definitions (for diagnostic use only, setup automatically, overwritten by configure_pop.py - DO NOT EDIT) |
| MARBL_NT | 0 | integer | build_component_pop | env_build.xml | None | pop marbl tracer count (this is runtime configurable in marbl but not in pop - do not edit) |
| POP_PHYS_CYCLE_YEARS_IN_CYCLE | 0 | integer | run_component_pop | env_run.xml | number of years to run before cycling POP physics
POP physics cycling only occurs if POP_PHYS_CYCLE_YEARS_IN_CYCLE>0
and pre- and post-run scripts are specified in env vars
PRERUN_SCRIPT and POSTRUN_SCRIPT |
|
| POP_PHYS_CYCLE_MONTHS_RUN_SINCE_CYCLE | 0 | integer | run_component_pop | env_run.xml | number of months run since most recent cycling of POP physics |
|
| POP_PASSIVE_TRACER_RESTART_OVERRIDE | none | char | run_component_pop | env_run.xml | if not equal to none, then passive tracers modules use this as their restart file |
