C | SUBROUTINE the_main_loop |

C | |

|
|
C | THE_MAIN_LOOP is the toplevel routine for the Tangent Linear and |
| 25 |
|
|
C | Adjoint Model Compiler (TAMC). For this purpose the initialization |
| 26 |
|
|
C | of the model was split into two parts. Those parameters that do |
| 27 |
|
|
C | not depend on a specific model run are set in INITIALISE_FIXED, |
| 28 |
|
|
C | whereas those that do depend on the specific realization are |
| 29 |
|
|
C | initialized in INITIALISE_VARIA. |
| 30 |
|
|
C | This routine is to be used in conjuction with the MITgcmuv |
| 31 |
|
|
C | checkpoint 37. |
