111	! Description:
112	! ------------
113	!> Radiation models and interfaces
114	!> @todo move variable definitions used in radiation_init only to the subroutine
115	!> as they are no longer required after initialization.
116	!> @todo Output of full column vertical profiles used in RRTMG
117	!> @todo Output of other rrtm arrays (such as volume mixing ratios)
118	!> @todo Adapt for use with topography
119	!>
120	!> @note Many variables have a leading dummy dimension (0:0) in order to
121	!> match the assume-size shape expected by the RRTMG model.
