which need to go in code/ |

| 32 |
|
Accordingly, bathy.0??.0??.data need changing. |

N.B. Domain decomposition nPy not active with exch2, i.e. |
| 35 |
|
possible decomps are (for orig. with 17 tiles): |

sNx = 90 30 90 30 |

sNy = 90 30 90 30 |

I've generated artificial tile #18 with all zeros |
| 44 |
|
blanklist.txt needs to be generated by hand. |
| 45 |

Not clear how many procs to invoke in presence of blank list. |

* Real bathymetry, 15 vertical levels, |
| 51 |
|
* monthly climatological forcing via exf package, uses |
| 52 |
|
4x4 deg. fields with on-the-fly interpolation |
| 53 |
|
* Bathymetry is generated via script ... in ... |
| 54 |
|
* Initial conditions for T, S are generated via script ... in ... |
| 55 |
|
|
| 56 |
|
All input fields can be downloaded using script input_15lev/prepare_run |
| 57 |
|
(which also contains link pattern to standard tile00${i}.mitgrid fields), |
| 58 |
|
then link to run directory. |
