15	! Calculation of turbulent fluxes with WS-scheme only for the whole model
16	! domain, not for user-defined subregions.

22	! Bugfix in calculation of vertical velocity skewness. The added absolute value
23	! avoid negative values in the root. Negative values of w'w' can occur at the
24	! top or bottom of the model domain due to degrading the order of advection
25	! scheme. Furthermore the calculation will be the same for all advection
26	! schemes.
27	!
28	! 696 2011-03-18 07:03:49Z raasch
29	! Bugfix: Summation of Wicker-Skamarock scheme fluxes and variances for all
30	! threads
31	!
32	! 678 2011-02-02 14:31:56Z raasch
33	! Bugfix in calculation of the divergence of vertical flux of resolved scale
34	! energy, pressure fluctuations, and flux of pressure fluctuation itself
35	!
36	! 673 2011-01-18 16:19:48Z suehring
37	! Top bc for the horizontal velocity variances added for ocean runs.
38	! Setting the corresponding bottom bc moved to advec_ws.
39	!
40	! 667 2010-12-23 12:06:00Z suehring/gryschka
41	! When advection is computed with ws-scheme, turbulent fluxes are already
42	! computed in the respective advection routines and buffered in arrays
43	! sums_xx_ws_l(). This is due to a consistent treatment of statistics with the
44	! numerics and to avoid unphysical kinks near the surface.
45	! So some if requests has to be done to dicern between fluxes from ws-scheme
46	! other advection schemes.
47	! Furthermore the computation of z_i is only done if the heat flux exceeds a
48	! minimum value. This affects only simulations of a neutral boundary layer and
49	! is due to reasons of computations in the advection scheme.
50	!
51	! 624 2010-12-10 11:46:30Z heinze
52	! Calculation of q*2 added

55	! optional barriers included in order to speed up collective operations
56	!
57	! 388 2009-09-23 09:40:33Z raasch
58	! Vertical profiles of potential density and hydrostatic pressure are
59	! calculated.
60	! Added missing timeseries calculation of w"q"(0), moved timeseries q* to the
61	! end.
62	! Temperature gradient criterion for estimating the boundary layer height
63	! replaced by the gradient criterion of Sullivan et al. (1998).
64	! Output of messages replaced by message handling routine.
65	!
66	! 197 2008-09-16 15:29:03Z raasch
67	! Spline timeseries splptx etc. removed, timeseries w'u', w'v', w'q' (k=0)
68	! added,
69	! bugfix: divide sums(k,8) (e) and sums(k,34) (e*) by ngp_2dh_s_inner(k,sr)
70	! (like other scalars)
71	!
72	! 133 2007-11-20 10:10:53Z letzel
73	! Vertical profiles now based on nzb_s_inner; they are divided by
74	! ngp_2dh_s_inner (scalars, procucts of scalars) and ngp_2dh (staggered
75	! velocity components and their products, procucts of scalars and velocity
76	! components), respectively.
77	!
78	! 106 2007-08-16 14:30:26Z raasch

83	! Statistics for ocean version (salinity, density) added,
84	! calculation of z_i and Deardorff velocity scale adjusted to be used with
85	! the ocean version
86	!
87	! 87 2007-05-22 15:46:47Z raasch
88	! Two more arguments added to user_statistics, which is now also called for
89	! user-defined profiles,
90	! var_hom and var_sum renamed pr_palm
91	!
92	! 82 2007-04-16 15:40:52Z raasch

96	! Collection of time series quantities moved from routine flow_statistics to

98	! moisture renamed humidity

112	! Description:
113	! ------------
114	! Compute average profiles and further average flow quantities for the different
115	! user-defined (sub-)regions. The region indexed 0 is the total model domain.
116	!
117	! NOTE: For simplicity, nzb_s_inner and nzb_diff_s_inner are being used as a
118	! ---- lower vertical index for k-loops for all variables, although strictly
119	! speaking the k-loops would have to be split up according to the staggered
120	! grid. However, this implies no error since staggered velocity components are
121	! zero at the walls and inside buildings.
