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. |
