| 7 | | Since r19xx an urban surface model (USM) is available in PALM. A brief description of the USM will follow here (see [wiki:doc/app/lsmpar#LandSurfaceParameters LSM description] as an example). It consists of a multi layer wall and soil model, predicting wall and soil temperature and moisture content, and a solver for the energy balance, predicting the temperature of the surface or the skin layer. Urban surfaces (building surfaces) are simulated using a tile approach. Each surface element consists of a fraction of bare wall/ roof, window and green elements (green roofs/ facades) with underlying soil layers (green roofs only) and a bare wall/ roof structure. |

| | 8 | All parts of the USM code are modularized in module [/browser/palm/trunk/SOURCE/urban_surface_mod.f90 urban_surface_mod]. In this context, a new Fortran namelist {{{urban_surface_parameters}}} was added, containing all USM-related steering parameters. The USM is automatically activated when an {{{urban_surface_parameter}}} is set in the parameter file ({{{_p3d}}}). |
