54	! Bugfix: for water surfaces, the initial water surface temperature is set equal
55	! to the intital skin temperature. Moreover, the minimum value of r_a is now
56	! 1.0 to avoid too large fluxes at the first model time step

71	! Changed: moved calculation of surface specific humidity to energy balance solver
72	! New: water surfaces are available by using a fixed sea surface temperature.
73	! The roughness lengths are calculated dynamically using the Charnock
74	! parameterization. This involves the new roughness length for moisture z0q.

76	! paved surfaces (i.e. asphalt concrete).

82	!
83	! 1757 2016-02-22 15:49:32Z maronga
84	! Bugfix: set tm_soil_m to zero after allocation. Added parameter
85	! unscheduled_radiation_calls to control calls of the radiation model based on
86	! the skin temperature change during one time step (preliminary version). Set
87	! qsws_soil_eb to zero at model start (previously set to qsws_eb). Removed MAX
88	! function as it cannot be vectorized.
89	!
90	! 1709 2015-11-04 14:47:01Z maronga

102	! Replaced rif with ol
103	!
104	! 1691 2015-10-26 16:17:44Z maronga

150	! Description:
151	! ------------
152	!> Land surface model, consisting of a solver for the energy balance at the
153	!> surface and a four layer soil scheme. The scheme is similar to the TESSEL
154	!> scheme implemented in the ECMWF IFS model, with modifications according to
155	!> H-TESSEL. The implementation is based on the formulation implemented in the
156	!> DALES and UCLA-LES models.
157	!>
158	!> @todo Consider partial absorption of the net shortwave radiation by the
159	!> skin layer.
160	!> @todo Improve surface water parameterization
161	!> @todo Invert indices (running from -3 to 0. Currently: nzb_soil=0,
162	!> nzt_soil=3)).
163	!> @todo Implement surface runoff model (required when performing long-term LES
164	!> with considerable precipitation.
165	!> @todo Fix crashes with radiation_scheme == 'constant'
166	!>
167	!> @note No time step criterion is required as long as the soil layers do not
168	!> become too thin.
