14	! When advection is computed with ws-scheme, turbulent fluxes are already
15	! computed in the respective advection routines and buffered in arrays
16	! sums_xx_ws_l(). This is due to a consistent treatment of statistics with the
17	! numerics and to avoid unphysical kinks near the surface.
18	! So some if requests has to be done to dicern between fluxes from ws-scheme
19	! other advection schemes.
20	! Furthermore the computation of z_i is only done if the heat flux exceeds a
21	! minimum value. This affects only simulations of a neutral boundary layer and
22	! is due to reasons of computations in the advection scheme.

85	! Description:
86	! ------------
87	! Compute average profiles and further average flow quantities for the different
88	! user-defined (sub-)regions. The region indexed 0 is the total model domain.
89	!
90	! NOTE: For simplicity, nzb_s_inner and nzb_diff_s_inner are being used as a
91	! ---- lower vertical index for k-loops for all variables, although strictly
92	! speaking the k-loops would have to be split up according to the staggered
93	! grid. However, this implies no error since staggered velocity components are
94	! zero at the walls and inside buildings.
