216	! Initial revision
217	!
218	!
219	! Description:
220	! ------------
221	!> Land surface model, consisting of a solver for the energy balance at the
222	!> surface and a multi layer soil scheme. The scheme is similar to the TESSEL
223	!> scheme implemented in the ECMWF IFS model, with modifications according to
224	!> H-TESSEL. The implementation is based on the formulation implemented in the
225	!> DALES and UCLA-LES models.
226	!>
227	!> @todo Restart data for vertical natural land-surfaces
228	!> @todo Extensive verification energy-balance solver for vertical surfaces,
229	!> e.g. parametrization of r_a
230	!> @todo Revise single land-surface processes for vertical surfaces, e.g.
231	!> treatment of humidity, etc.
232	!> @todo Consider partial absorption of the net shortwave radiation by the
233	!> skin layer.
234	!> @todo Improve surface water parameterization
235	!> @todo Invert indices (running from -3 to 0. Currently: nzb_soil=0,
236	!> nzt_soil=3)).
237	!> @todo Implement surface runoff model (required when performing long-term LES
238	!> with considerable precipitation.
239	!> @todo Fix crashes with radiation_scheme == 'constant'
240	!> @todo Revise calculation of f2 when wilting point is non-constant in the
241	!> soil
242	!> @todo Solve problems with soil heat flux paramterization
243	!> @todo Make pavement_depth variable for each surface element
244	!> @todo Allow for zero soil moisture (currently, it is set to wilting point)
245	!> @note No time step criterion is required as long as the soil layers do not
246	!> become too thin.
