12	! Bugfix in calculation of vertical velocity skewness. The added absolute value
13	! avoid negative values in the root. Negative values of w'w' can occur at the
14	! top or bottom of the model domain due to degrading the order of advection
15	! scheme. Furthermore the calculation will be the same for all advection
16	! schemes.
17	!
18	! 696 2011-03-18 07:03:49Z raasch
19	! Bugfix: Summation of Wicker-Skamarock scheme fluxes and variances for all
20	! threads
21	!
22	! 678 2011-02-02 14:31:56Z raasch
23	! Bugfix in calculation of the divergence of vertical flux of resolved scale
24	! energy, pressure fluctuations, and flux of pressure fluctuation itself
25	!
26	! 673 2011-01-18 16:19:48Z suehring
27	! Top bc for the horizontal velocity variances added for ocean runs.
28	! Setting the corresponding bottom bc moved to advec_ws.
29	!
30	! 667 2010-12-23 12:06:00Z suehring/gryschka
31	! When advection is computed with ws-scheme, turbulent fluxes are already
32	! computed in the respective advection routines and buffered in arrays
33	! sums_xx_ws_l(). This is due to a consistent treatment of statistics with the
34	! numerics and to avoid unphysical kinks near the surface.
35	! So some if requests has to be done to dicern between fluxes from ws-scheme
36	! other advection schemes.
37	! Furthermore the computation of z_i is only done if the heat flux exceeds a
38	! minimum value. This affects only simulations of a neutral boundary layer and
39	! is due to reasons of computations in the advection scheme.
40	!
41	! 624 2010-12-10 11:46:30Z heinze
42	! Calculation of q*2 added
43	!
44	! 622 2010-12-10 08:08:13Z raasch
45	! optional barriers included in order to speed up collective operations
46	!
47	! 388 2009-09-23 09:40:33Z raasch
48	! Vertical profiles of potential density and hydrostatic pressure are
49	! calculated.
50	! Added missing timeseries calculation of w"q"(0), moved timeseries q* to the
51	! end.
52	! Temperature gradient criterion for estimating the boundary layer height
53	! replaced by the gradient criterion of Sullivan et al. (1998).
54	! Output of messages replaced by message handling routine.
55	!
56	! 197 2008-09-16 15:29:03Z raasch
57	! Spline timeseries splptx etc. removed, timeseries w'u', w'v', w'q' (k=0)
58	! added,
59	! bugfix: divide sums(k,8) (e) and sums(k,34) (e*) by ngp_2dh_s_inner(k,sr)
60	! (like other scalars)
61	!
62	! 133 2007-11-20 10:10:53Z letzel
63	! Vertical profiles now based on nzb_s_inner; they are divided by
64	! ngp_2dh_s_inner (scalars, procucts of scalars) and ngp_2dh (staggered
65	! velocity components and their products, procucts of scalars and velocity
66	! components), respectively.
67	!
68	! 106 2007-08-16 14:30:26Z raasch
69	! Prescribed momentum fluxes at the top surface are used,
70	! profiles for wp and w"e are calculated
71	!
72	! 97 2007-06-21 08:23:15Z raasch
73	! Statistics for ocean version (salinity, density) added,
74	! calculation of z_i and Deardorff velocity scale adjusted to be used with
75	! the ocean version
76	!
77	! 87 2007-05-22 15:46:47Z raasch
78	! Two more arguments added to user_statistics, which is now also called for
79	! user-defined profiles,
80	! var_hom and var_sum renamed pr_palm
81	!
82	! 82 2007-04-16 15:40:52Z raasch
83	! Cpp-directive lcmuk changed to intel_openmp_bug
84	!
85	! 75 2007-03-22 09:54:05Z raasch
86	! Collection of time series quantities moved from routine flow_statistics to
87	! here, routine user_statistics is called for each statistic region,
88	! moisture renamed humidity
89	!
90	! 19 2007-02-23 04:53:48Z raasch
91	! fluxes at top modified (tswst, qswst)
92	!

102	! Description:
103	! ------------
104	! Compute average profiles and further average flow quantities for the different
105	! user-defined (sub-)regions. The region indexed 0 is the total model domain.
106	!
107	! NOTE: For simplicity, nzb_s_inner and nzb_diff_s_inner are being used as a
108	! ---- lower vertical index for k-loops for all variables, although strictly
109	! speaking the k-loops would have to be split up according to the staggered
110	! grid. However, this implies no error since staggered velocity components are
111	! zero at the walls and inside buildings.
