88	! unscheduled_radiation_calls to control calls of the radiation model based on
89	! the skin temperature change during one time step (preliminary version). Set
90	! qsws_soil_eb to zero at model start (previously set to qsws_eb). Removed MAX

153	! Description:
154	! ------------
155	!> Land surface model, consisting of a solver for the energy balance at the
156	!> surface and a four layer soil scheme. The scheme is similar to the TESSEL
157	!> scheme implemented in the ECMWF IFS model, with modifications according to
158	!> H-TESSEL. The implementation is based on the formulation implemented in the
159	!> DALES and UCLA-LES models.
160	!>
161	!> @todo Consider partial absorption of the net shortwave radiation by the
162	!> skin layer.
163	!> @todo Improve surface water parameterization
164	!> @todo Invert indices (running from -3 to 0. Currently: nzb_soil=0,
165	!> nzt_soil=3)).
166	!> @todo Implement surface runoff model (required when performing long-term LES
167	!> with considerable precipitation.
168	!> @todo Fix crashes with radiation_scheme == 'constant'
169	!>
170	!> @note No time step criterion is required as long as the soil layers do not
171	!> become too thin.
