C | SUBROUTINE INI_SALT | |

C | o Set model initial salinity field. | |

C |==========================================================| |
| 11 |
C | There are several options for setting the initial | |
| 12 |
C | temperature file | |
| 13 |
C | 1. Inline code | |
| 14 |
C | 2. Vertical profile ( uniform S in X and Y ) | |
| 15 |
C | 3. Three-dimensional data from a file. For example from | |
| 16 |
C | Levitus or from a checkpoint file from a previous | |
| 17 |
C | integration. | |
| 18 |
C | In addition to setting the salinity field we also | |
| 19 |
C | set the initial salinity tendency term here. | |
