15	! ngp_2dh_s_inner (scalars, procucts of scalars) and ngp_2dh (staggered
16	! velocity components and their products, procucts of scalars and velocity
17	! components), respectively.

53	! Description:
54	! ------------
55	! Compute average profiles and further average flow quantities for the different
56	! user-defined (sub-)regions. The region indexed 0 is the total model domain.
57	!
58	! NOTE: For simplicity, nzb_s_inner and nzb_diff_s_inner are being used as a
59	! ---- lower vertical index for k-loops for all variables, although strictly
60	! speaking the k-loops would have to be split up according to the staggered
61	! grid. However, this implies no error since staggered velocity components are
62	! zero at the walls and inside buildings.
