30	!
31	! 3646 2018-12-28 17:58:49Z kanani
32	! Remove check for simulated_time > 0, it is not required since biometeorology
33	! is only called from time_integration and not during time_integration_spinup
34	!
35	! 3614 2018-12-10 07:05:46Z raasch

45	! and bio_3d_data_averaging,
46	! dom_dwd_user, Schrempf:
47	! - integration of UVEM module part from r3474 (edited)
48	! - split UTCI regression into 6 parts
49	! - all data_output_3d is now explicity casted to sp

85	!>
86	!> @todo Alphabetical sorting of "USE ..." lists, "ONLY" list, variable declarations
87	!> (per subroutine: first all CHARACTERs, then INTEGERs, LOGICALs, REALs, )
88	!> @todo Comments start with capital letter --> "!-- Include..."
89	!> @todo uv_vitd3dose-->new output type necessary (cumulative)
90	!> @todo consider upwelling radiation in UV
