34	! Bugfix: Calculation of subgridscale buoyancy flux for humidity and cloud
35	! droplets at nzb and nzt added

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

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

66	! 667 2010-12-23 12:06:00Z suehring/gryschka
67	! When advection is computed with ws-scheme, turbulent fluxes are already
68	! computed in the respective advection routines and buffered in arrays
69	! sums_xx_ws_l(). This is due to a consistent treatment of statistics with the
70	! numerics and to avoid unphysical kinks near the surface.
71	! So some if requests has to be done to dicern between fluxes from ws-scheme
72	! other advection schemes.
73	! Furthermore the computation of z_i is only done if the heat flux exceeds a
74	! minimum value. This affects only simulations of a neutral boundary layer and
75	! is due to reasons of computations in the advection scheme.

84	! Vertical profiles of potential density and hydrostatic pressure are
85	! calculated.
86	! Added missing timeseries calculation of w"q"(0), moved timeseries q* to the
87	! end.
88	! Temperature gradient criterion for estimating the boundary layer height
89	! replaced by the gradient criterion of Sullivan et al. (1998).

93	! Spline timeseries splptx etc. removed, timeseries w'u', w'v', w'q' (k=0)
94	! added,
95	! bugfix: divide sums(k,8) (e) and sums(k,34) (e*) by ngp_2dh_s_inner(k,sr)
96	! (like other scalars)
97	!
98	! 133 2007-11-20 10:10:53Z letzel
99	! Vertical profiles now based on nzb_s_inner; they are divided by
100	! ngp_2dh_s_inner (scalars, procucts of scalars) and ngp_2dh (staggered
101	! velocity components and their products, procucts of scalars and velocity
102	! components), respectively.

138	! Description:
139	! ------------
140	! Compute average profiles and further average flow quantities for the different
141	! user-defined (sub-)regions. The region indexed 0 is the total model domain.
142	!
143	! NOTE: For simplicity, nzb_s_inner and nzb_diff_s_inner are being used as a
144	! ---- lower vertical index for k-loops for all variables, although strictly
145	! speaking the k-loops would have to be split up according to the staggered
146	! grid. However, this implies no error since staggered velocity components are
147	! zero at the walls and inside buildings.
