	29	!
[1977]	30	! 1976 2016-07-27 13:28:04Z maronga
	31	! Parts of the code have been reformatted. Use of radiation model output is
	32	! generalized and simplified. Added more output quantities due to modularization
	33	!
[1973]	34	! 1972 2016-07-26 07:52:02Z maronga
	35	! Further modularization: output of cross sections and 3D data is now done in this
	36	! module. Moreover, restart data is written and read directly within this module.
	37	!
	38	!
[1967]	39	! 1966 2016-07-18 11:54:18Z maronga

	47	! Bugfix: for water surfaces, the initial water surface temperature is set equal
	48	! to the intital skin temperature. Moreover, the minimum value of r_a is now
	49	! 1.0 to avoid too large fluxes at the first model time step
	50	!
[1851]	51	! 1849 2016-04-08 11:33:18Z hoffmann
	52	! prr moved to arrays_3d

	60	!
[1789]	61	! 1788 2016-03-10 11:01:04Z maronga
[1788]	62	! Bugfix: calculate lambda_surface based on temperature gradient between skin
	63	! layer and soil layer instead of Obukhov length
	64	! Changed: moved calculation of surface specific humidity to energy balance solver
	65	! New: water surfaces are available by using a fixed sea surface temperature.
	66	! The roughness lengths are calculated dynamically using the Charnock
	67	! parameterization. This involves the new roughness length for moisture z0q.
	68	! New: modified solution of the energy balance solver and soil model for
	69	! paved surfaces (i.e. asphalt concrete).
	70	! Syntax layout improved.
	71	! Changed: parameter dewfall removed.
[1758]	72	!

	75	!
[1758]	76	! 1757 2016-02-22 15:49:32Z maronga
[1757]	77	! Bugfix: set tm_soil_m to zero after allocation. Added parameter
	78	! unscheduled_radiation_calls to control calls of the radiation model based on
	79	! the skin temperature change during one time step (preliminary version). Set
	80	! qsws_soil_eb to zero at model start (previously set to qsws_eb). Removed MAX

	86	! Bugfix: zero resistance caused crash when using radiation_scheme = 'clear-sky'
	87	! Bugfix: calculation of rad_net when using radiation_scheme = 'clear-sky'
	88	! Added todo action
[1698]	89	!

	143	! Description:
	144	! ------------
[1682]	145	!> Land surface model, consisting of a solver for the energy balance at the
	146	!> surface and a four layer soil scheme. The scheme is similar to the TESSEL
	147	!> scheme implemented in the ECMWF IFS model, with modifications according to
	148	!> H-TESSEL. The implementation is based on the formulation implemented in the
	149	!> DALES and UCLA-LES models.
	150	!>
[1691]	151	!> @todo Consider partial absorption of the net shortwave radiation by the
[1709]	152	!> skin layer.
[1788]	153	!> @todo Improve surface water parameterization
[1691]	154	!> @todo Invert indices (running from -3 to 0. Currently: nzb_soil=0,
	155	!> nzt_soil=3)).
	156	!> @todo Implement surface runoff model (required when performing long-term LES
	157	!> with considerable precipitation.
[1709]	158	!> @todo Fix crashes with radiation_scheme == 'constant'
[1682]	159	!>
[1709]	160	!> @note No time step criterion is required as long as the soil layers do not
	161	!> become too thin.
