Update of the boundary conditions in MESSy-CLaMS

The routines for updating the boundary conditions are called in clamsbmix_global_end (messy_clamsbmix_si.f90).

There are two routines for updating the boundary conditions:

  • bmix: replace lowest, highest and/or vertical layers (layers used for mixing)

  • replace_boundaries: set boundary conditions below or above a specified zeta-level and within a specified period
