29	! Enable turbulent inflow for passive_scalar and humidity
30	!
31	! 1560 2015-03-06 10:48:54Z keck
32	! Option recycling_yshift added. If this option is switched on, the turbulence
33	! data, which is mapped from the recycling plane to the inflow, is shifted in
34	! y direction (by ny * dy / 2 )
35	!
36	! 1353 2014-04-08 15:21:23Z heinze
37	! REAL constants provided with KIND-attribute
38	!
39	! 1346 2014-03-27 13:18:20Z heinze
40	! Bugfix: REAL constants provided with KIND-attribute especially in call of
41	! intrinsic function like MAX, MIN, SIGN
42	!
43	! 1320 2014-03-20 08:40:49Z raasch
44	! ONLY-attribute added to USE-statements,
45	! kind-parameters added to all INTEGER and REAL declaration statements,
46	! kinds are defined in new module kinds,
47	! revision history before 2012 removed,
48	! comment fields (!:) to be used for variable explanations added to
49	! all variable declaration statements
50	!
51	! 1092 2013-02-02 11:24:22Z raasch
52	! unused variables removed
53	!
54	! 1036 2012-10-22 13:43:42Z raasch
55	! code put under GPL (PALM 3.9)

57	! Initial version (2008/03/07)

59	! Description:
60	! ------------
61	! Imposing turbulence at the respective inflow using the turbulence
62	! recycling method of Kataoka and Mizuno (2002).
