13	! Spline timeseries splptx etc. removed, timeseries w'u', w'v', w'q' (k=0)
14	! added,
15	! bugfix: divide sums(k,8) (e) and sums(k,34) (e*) by ngp_2dh_s_inner(k,sr)
16	! (like other scalars)

19	! Vertical profiles now based on nzb_s_inner; they are divided by
20	! ngp_2dh_s_inner (scalars, procucts of scalars) and ngp_2dh (staggered
21	! velocity components and their products, procucts of scalars and velocity
22	! components), respectively.

58	! Description:
59	! ------------
60	! Compute average profiles and further average flow quantities for the different
61	! user-defined (sub-)regions. The region indexed 0 is the total model domain.
62	!
63	! NOTE: For simplicity, nzb_s_inner and nzb_diff_s_inner are being used as a
64	! ---- lower vertical index for k-loops for all variables, although strictly
65	! speaking the k-loops would have to be split up according to the staggered
66	! grid. However, this implies no error since staggered velocity components are
67	! zero at the walls and inside buildings.
