 All parts of the LSM code are modularized in module [/browser/palm/trunk/SOURCE/land_surface_model.f90 land_surface_model_mod]. In this context, a new Fortran NAMELIST {{{lsm_par}}} was added, containing all LSM-related steering parameters. The LSM is automatically activated when a {{{lsm_par}}} is set in the parameter file ({{{_p3d}}}). The user can easily set all relevant LSM parameters by choosing between 3 different surface types (vegetation, pavement, water) and various pre-defined surface classes 17 pre-defined [#vegetation_type vegetation types], 7 pre-defined [#pavement_type pavement type]s, 4 pre-defined [#water_type water types], and 6 different [#soil_type soil types]. The default setting of the LSM is a soil of medium porosity covered to 85% with short grass. It is also possible to modify the pre-defined vegetation/soil types by overwriting some of the parameters. Moreover it is possible to create user-defined vegetation and soil types from scratch.
 
-A minimum configuration of the LSM requires setting of the parameters [#soil_type soil_type], [#vegetation_type vegetation_type], [#soil_temperature soil_temperature], and [#soil_moisture soil_moisture]. 
+A minimum configuration of the LSM requires setting of the parameters [#soil_type soil_type], [#vegetation_type vegetation_type], [#soil_temperature soil_temperature], [#deep_soil_temperature deep_soil_temperature], and [#soil_moisture soil_moisture]. 
 
 Note that the use of the LSM requires using a [wiki:doc/tec/radiation radiation model].

-The first eight values here represent the temperature of the soil layers (defined at the center of the layers of depths [#dz_soil dz_soil]. An additional value must be provided (here the ninth) which represents the bottom boundary condition (deep soil temperature). Note that this implies that for N soil layers, soil_temperature requires N+1 values, while soil_moisture and dz_soil both must be of size N.
