	78	! Description:
	79	! ------------
[1682]	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!
