28	! Enable turbulent inflow for passive_scalar and humidity
29	!
30	! 1560 2015-03-06 10:48:54Z keck
31	! Option recycling_yshift added. If this option is switched on, the turbulence
32	! data, which is mapped from the recycling plane to the inflow, is shifted in
33	! y direction (by ny * dy / 2 )

41	!
42	! 1320 2014-03-20 08:40:49Z raasch
43	! ONLY-attribute added to USE-statements,
44	! kind-parameters added to all INTEGER and REAL declaration statements,
45	! kinds are defined in new module kinds,
46	! revision history before 2012 removed,
47	! comment fields (!:) to be used for variable explanations added to
