Instructions for using pkg/ptracers to compute tracer |

Green's functions for Gruber's ocean inversion project |

(see quercus.igpp.ucla.edu/OceanInversion/ for details). |

|

Preprocessed OceanInversion input files are available |
| 9 |
under directories region_mask, takahashi, and |
| 10 |
atm_co2 in this package. All netcdf input files |
| 11 |
have been converted to binary format in order to avoid |
| 12 |
having to link netcdf library with MITgcm code. See |
| 13 |
respective README files in each directory for details. |

=============================================== |

First check that pkg/ptracers works OK by using |
| 18 |
salinity initial and boundary conditions |

1 ===> get MITgcm code from cvs repository |

| 24 |
cvs login ( CVS password: cvsanon ) |

| 26 |
|
| 27 |
2 ===> put MITgcm_contrib/ocean_inversion_project in MITgcm directory |

| 29 |
cd MITgcm |

5 ===> check that PTRACER output for tracer 1 and tracer 30 |
| 57 |
===> is identical to salinity output |
| 58 |
