| 2 | ======================= | 
| 3 |  | 
| 4 | Instructions for using pkg/ptracers to compute tracer | 
| 5 | Green's functions for Gruber's ocean inversion project | 
| 6 | (see quercus.igpp.ucla.edu/OceanInversion/ for details). | 
| 7 |  | 
| 8 | 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. | 
| 14 |  | 
| 15 |  | 
| 16 | =============================================== | 
| 17 | First check that pkg/ptracers works OK by using | 
| 18 | salinity initial and boundary conditions | 
| 19 | =============================================== | 
| 20 |  | 
| 21 | 1 ===> get MITgcm code from cvs repository |

| 24 | cvs login ( CVS password: cvsanon ) | 
| 25 | cvs co MITgcm | 
| 26 |  | 
| 27 | 2 ===> put MITgcm_contrib/ocean_inversion_project in MITgcm directory | 
| 28 |  | 
| 29 | cd MITgcm | 
| 30 | cvs co -d ocean_inversion_project MITgcm_contrib/ocean_inversion_project | 
| 31 |  |

| 55 |  | 
| 56 | 5 ===> check that PTRACER output for tracer 1 and tracer 30 | 
| 57 | ===> is identical to salinity output | 
| 58 |  |
