[[TracNav(doc/app/partoc|nocollapse)]]

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.

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}}}).
