79	! ------------
80	!> Advection term for scalar variables using the Piacsek and Williams scheme
81	!> (form C3). Contrary to PW itself, for reasons of accuracy their scheme is
82	!> slightly modified as follows: the values of those scalars that are used for
83	!> the computation of the flux divergence are reduced by the value of the
84	!> relevant scalar at the location where the difference is computed (sk(k,j,i)).
85	!> NOTE: at the first grid point above the surface computation still takes place!
