| Parameter Name | Default Value | Data Type | Group | CASEROOT File | Valid Values | Description |
|---|---|---|---|---|---|---|
| COMP_ICE | dice | char | case_comp | env_case.xml | ['dice'] | Name of ice component |
| DICE_MODE | ssmi | char | run_component_dice | env_run.xml | ['prescribed', 'ssmi', 'ssmi_iaf', 'copyall', 'null'] | DICE mode. 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 POP 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. |
