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