v25 v26 2 2 3 3 == Overview == 4 Since r1551 a full land surface model (LSM) is available in PALM (see [source:palm/trunk/SOURCE/land_surface_model .f90 land_surface_model.f90]). It consists of a four layer soil model, predicting soil temperature and moisture content, and a solver for the energy balance, predicting the temperature of the skin layer. Moreover, a liquid water reservoir accounts for the presence of liquid water on plants and soil due to precipitation. The implementation is based on the ECMWF-IFS land surface parametrization (H-TESSEL) and its adaptation in the DALES model ([#heus Heus et al. 2010]).4 Since r1551 a full land surface model (LSM) is available in PALM (see [source:palm/trunk/SOURCE/land_surface_model_mod.f90 land_surface_model_mod.f90]).
