61	! Bugfix in calculation of vertical velocity skewness. The added absolute value
62	! avoid negative values in the root. Negative values of w'w' can occur at the
63	! top or bottom of the model domain due to degrading the order of advection
64	! scheme. Furthermore the calculation will be the same for all advection
65	! schemes.

76	! Top bc for the horizontal velocity variances added for ocean runs.
77	! Setting the corresponding bottom bc moved to advec_ws.

79	! 667 2010-12-23 12:06:00Z suehring/gryschka
80	! When advection is computed with ws-scheme, turbulent fluxes are already
81	! computed in the respective advection routines and buffered in arrays
82	! sums_xx_ws_l(). This is due to a consistent treatment of statistics with the
83	! numerics and to avoid unphysical kinks near the surface.
84	! So some if requests has to be done to dicern between fluxes from ws-scheme
85	! other advection schemes.
86	! Furthermore the computation of z_i is only done if the heat flux exceeds a
87	! minimum value. This affects only simulations of a neutral boundary layer and
88	! is due to reasons of computations in the advection scheme.

99	! Added missing timeseries calculation of w"q"(0), moved timeseries q* to the
100	! end.
101	! Temperature gradient criterion for estimating the boundary layer height

109	! (like other scalars)
110	!
111	! 133 2007-11-20 10:10:53Z letzel
112	! Vertical profiles now based on nzb_s_inner; they are divided by

151	! Description:
152	! ------------
153	! Compute average profiles and further average flow quantities for the different
154	! user-defined (sub-)regions. The region indexed 0 is the total model domain.
155	!
156	! NOTE: For simplicity, nzb_s_inner and nzb_diff_s_inner are being used as a
157	! ---- lower vertical index for k-loops for all variables, although strictly
158	! speaking the k-loops would have to be split up according to the staggered
159	! grid. However, this implies no error since staggered velocity components are
160	! zero at the walls and inside buildings.
