| 4 | | Since r1551 a full land surface model (LMS) is available in PALM. It consists of a four layer soil model for the soil temperature and moisture contents and a solver for the energy balance at the surface. The implementation is based on the ECMWF-IFS land surface parametrization (TESSEL) and its adaption in the DALES model. |

| 6 | | 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}}}). |

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 19 pre-defined [#veg_type vegetation types] and 7 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. |
