The local copy of S/R aim_surf_bc.F (in code directory) provide |
| 9 |
|
a) the SST field (hard coded). |
| 10 |
|
b) the time in the year is fixed and corresponds to the spring equinox; |
| 11 |
|
this ensures a symetric forcing between N & S hemispheres. |

|
The model uses the standard 5-level vertical resolution of the Speedy_v23 |
| 13 |
|
code; the horizontal resolution is 2.8125 with 128x23 grid points. |

o To reproduce the run : |
| 18 |
|
|
| 19 |
|
The genmake options are in .genmakerc, so that the simplest form |
| 20 |
|
of genmake can be used : |
| 21 |
|
cd build |
| 22 |
|
../../../tools/genmake2 -mods=../code [-of= ... if needed] |
| 23 |
|
make depend |
| 24 |
|
make |
| 25 |
|
|
| 26 |
|
ln -s ../input/* . |

Notes: |
| 31 |
|
* To produce a short test that is relevant for the Atmosphere physics part, |
| 32 |
|
a restart file (pickup.0000051840) is included. The model reaches |
| 33 |
|
a statistical equilibrium after 1 year. |
| 34 |
|
* the file aim_SST.* contains the SST field. |
| 35 |
|
* Since aim pkg uses arrays with MAX_NO_THREADS as dimension, the maximum |
| 36 |
|
number of treads is set to 1 (in code/EEPARAMS.h) instead of 32, so that the |
| 37 |
|
size of the executable is reduced. This obviously needs to be changed |
| 38 |
|
before compiling on a multi-threaded platform. |

|
Northern boundary : |
| 41 |
|
o initially, the domain (SIZE.h) 128x24x5 with a land line as the Northern |
| 42 |
|
boundary, reduciong the effective domain to 128x23x5. |
| 43 |
|
o To have a more efficient code (and a good starting point for MIT Atmos. |
| 44 |
|
Physics), the new domain (SIZE.h) is now 128x23x5 . |
| 45 |
|
Northern and Southern boundaries are "closed" like the in Lat-Lon set-up. |
