    7878Allowed are the values  'dirichlet'  (cs(k=nz+1) does not change during the run),  'neumann'  (cs(k=nz+1) = cs(k=nz)),
    79 
    80 ### RFo No idea whther this really works für cs
    8179and  'initial_gradient' .
    8280With the  'initial_gradient'  boundary condition the value of the scalar concentration gradient at the top is calculated from the initial scalar concentration profile (see cs_surface, cs_vertical_gradient) by: bc_cs_t_val = (cs_init(k=nz) - ss_init(k=nz-1)) / dzu(nz). Using this value (assumed constant during the run) the concentration boundary values are calculated as
    83 
    84 
    8581cs(k=nz+1) = cs(k=nz) + bc_cs_t_val * dzu(nz+1)
    86 
    8782(up to k=nz the prognostic equation for the chemical species concentration is solved).
    88 ###
    8983
    9084When a constant cs flux is used at the top boundary (top_csflux), bc_cs_t = 'neumann' must be used, because otherwise the resolved scale may contribute to the top flux so that a constant value cannot be guaranteed.
