24	! Description:
25	! ------------
26	! Compute average profiles and further average flow quantities for the different
27	! user-defined (sub-)regions. The region indexed 0 is the total model domain.
28	!
29	! NOTE: For simplicity, nzb_s_outer and nzb_diff_s_outer are being used as a
30	! ---- lower vertical index for k-loops for all variables so that regardless
31	! of the variable and its respective staggered grid always the same number of
32	! grid points is used for 2D averages. The disadvantage: depending on the
33	! variable, up to one grid layer adjacent to the (vertical walls of the)
34	! topography is missed out by this simplification.
