Instructions for running Experiment 1 |
|
|
===================================== |
|
|
|
|
|
This is a 1-cpu, 10-hour integration used to make sure that all |
|
|
the files are available and that the sea-ice model compiles and |
|
|
runs. The reading of atmospheric forcing files and the computation |
|
|
of open-water bulk fluxes are carried out within pkg/seaice. |

Instructions for running Experiment 2 |

|
|
compared to that of experiment 1, which used the LSR solver. |

Instructions for running Experiment 3 |
|
|
===================================== |
|
|
|
|
|
This is a test of periodic boundary conditions for LSR |
|
|
and ADI solvers. The domain has a flat bottom and |
|
|
is periodic both in the x and the y directions. |
|
|
All forcing files are null or constant (u10m = v10m = 5 m/s). |
|
|
|
|
|
To run Experiment 3: |
|
|
cd ../../../verification/lab_sea/input |
|
|
ln -sf DATA.1hour data |

|
|
mkdir exp3b |
|
|
mv *tave.0000000001.data exp3b |
|
|
|
|
|
Use matlab script lookat_exp3.m to look at |
|
|
results from exp3a and exp3b: |
|
|
cd ../../../verification/lab_sea/matlab |
|
|
matlab |
|
|
lookat_exp3 |
|
|
|
|
|
Both solvers should and do converge to solutions |
|
|
that are constant at each latitude. But note that |
|
|
the two solutions are not exactly the same because |
|
|
the two solvers represent slightly different |
|
|
approximations of the viscous/plastic equations. |
|
|
|
|
|
|
|
|
Instructions for running Experiment 4 |
|
|
===================================== |
|
|
|
|
|
This is a 2-cpu, 10-hour integration used to test |
|
|
tile edges for sea-ice dynamic solvers. |
|
|
|
|
|
To run Experiment 4: |
|
|
cd ../../../verification/lab_sea/input |
|
|
ln -sf DATA.10hours data |
|
|
ln -sf DATA.SEAICE.lsr data.seaice |
|

|
|
mkdir exp4 |
|
|
mv *tave.0000000010.data exp4 |
|
|
|
|
|
Use the matlab script lookat_exp4.m to compare |
|
|
the 2-cpu output to that of exp1: |
|
|
cd ../../../verification/lab_sea/matlab |
|
|
matlab |
|
|
lookat_exp4 |
|
|
|
|
|
The accuracy of the dynamic solvers is increased by |
|
|
reducing parameter LSR_ERROR for the LSR solver and |
|
|
by increasing parameter NPSEUDO for the ADI solver. |
|
|
The computational cost/accuracy trade-off is quite |
|
|
high for the ADI solver but relatively small for |
|
|
the LSR solver, which is the default solver. |
|
|
|
|
|
|
|
|
Instructions for running Experiment 5 |
|
|
===================================== |
|
|
|
|
|
This is a 2-cpu, 2-year, test integration. It illustrates |
|
|
convention used by seaice_get_forcing.F for multi-year forcing. |
|
|
|
|
|
To run Experiment 5: |
