OBSERVATION SYSTEM SIMULATION EXPERIMENT |
| 4 |
|
| 5 |
OSSE is an MITgcm configuration to simulate data assimilation with a |
| 6 |
deterministic ensemble Kalman filter and a model of a rotating tank of |
| 7 |
water with an ice bucket at the center. |

INSTALLATION |
| 10 |
|
| 11 |
At the time of this writing, the OSSE requires MITgcm checkpoint48 to |
| 12 |
compile and run. MITgcm can be obtained from |
| 13 |
<http://mitgcm.org/source_code.html>. If downloading from the CVS |
| 14 |
server, use the command |
| 15 |
|
| 16 |
cvs co -r 'checkpoint48' MITgcm |
| 17 |
|
| 18 |
in order to specify the correct version. Read the instructions on the |
| 19 |
the webpage before trying to use the CVS server. |
| 20 |
|
| 21 |
The OSSE directory tree can be obtained from the MITgcm CVS repository |
| 22 |
with the command |
| 23 |
|
| 24 |
cvs co MITgcm_contrib/osse |
| 25 |
|
| 26 |
The code and its revision history can be browsed at |
| 27 |
|
| 28 |
<http://dev.mitgcm.org/cgi-bin/viewcvs.cgi/MITgcm_contrib/osse/> |
| 29 |
|
| 30 |
A good place to put the osse directory tree is in MITgcm/verification, |
| 31 |
where examples and test examples of MITgcm configurations are kept. |
