114	! Description:
115	! ------------
116	!> Radiation models and interfaces
117	!> @todo move variable definitions used in radiation_init only to the subroutine
118	!> as they are no longer required after initialization.
119	!> @todo Output of full column vertical profiles used in RRTMG
120	!> @todo Output of other rrtm arrays (such as volume mixing ratios)
121	!> @todo Adapt for use with topography
122	!>
123	!> @note Many variables have a leading dummy dimension (0:0) in order to
124	!> match the assume-size shape expected by the RRTMG model.
