* Real bathymetry, 15 vertical levels, |
| 54 |
|
|
* monthly climatological forcing via exf package, uses |

4x4 deg. fields with on-the-fly interpolation |

* Bathymetry is generated via script ... in ... |

All input fields can be downloaded using script input_15lev/prepare_run |
| 60 |
|
|
(which also contains link pattern to standard tile00${i}.mitgrid fields), |
| 61 |
|
|
then link to run directory. |

|
* forced by 6-hourly NCEP atmos. state, uses original reduced Gaussian grid |

and exf interpolation on-the-fly |

|
|
* initial conditions generated via scripts in |
| 71 |
|
|
MITgcm_contrib/eh3/llc/ecco-godae/climatology/ |
| 72 |
|

resulting fields are |

|
|
llc90x90x360_50lev_ptemp.bin, llc90x90x360_50lev_salt.bin |
| 74 |

these fields are run are run with a diffusion/conv.adj. setup of MITgcm |
| 75 |
