Parameters
Before running the model you can change the default paramter settings by editing
the file run.param. Here in the input, output paramter tables the listed
parameters are mostly used. They form only a subset of the total set of paramters
in the file run.param.
| Input Parameter | Description | Default Value |
|---|---|---|
| dts | Time step for scalars | 86400 |
| dtu | Time step for baroclinic mode | 10800 |
| dtb | Time step for barotropic mode | 300 |
| nitrun | Number of main iterations of the model | 36000 |
| kinput | 0/2 restart from binary fiele. 1/3 restart from netCDF file | 0 |
| koutpu | 0/2 output to binary fiele. 1/3 output to netCDF file | 0 |
| kstart | 0 ocean at rest, no sea-ice. 1 follow up a run. 3 ocean not at rest, sea-ice prescribed | 1 |
| Output Parameter | Description | Default Value |
|---|---|---|
| nsav | Write restart file every nsav iterations | 360 |
| ninfo | Write information in evolu every ninfo iteration | 30 |
| ntmoy | Average over ninfo iterations (1 or 2) or not (0) | 1 |
| nwjl | Frequency of output local daily values (year) | 1 |
| nwm | Frequency of output monthly means (year) | 1 |
| nwa | Frequency of output annual means (year) | 1 |
| nwtom | Output monthly mean U,V,T,S fields on all levels (1) or not (0) | 0 |
| nwtoa | Output yearly mean U,V,T,S fields on all levels (1) or not (0) | 0 |
| nwtest | 0: write output in years:nw(..), 2*nw(..), ... 1: write output in years:1, nw(..)+1, 2*nw(..)+1, ... | 0 |
| nwtal | Write whole period monthly means (1) or not (0) | 1 |
Input Files
The input files that are required to run the clio model are
listed in the table below.
| Input File | Description |
|---|---|
| run.param | Set input, output parameters |
| output.param | Set paramter for output |
| dynami.param | Set ice dynamic paramters |
| thermo.param | Set ice thermodynamic parameters |
| rest.om | Restart file for clio |
| cpointj.dat | Asci file contains points for ice local daily output |
Output files
The program creates the several output files in which it stores the
results of the simulation. These files are listed in the following
table.
| Output File | Contents |
