880 | | In case of [../inipar#topography topography] = '' 'read_from_file' '' the subroutine {{{init_grid}}} reads the topography information. |
881 | | Topography information can be further split-up into building and orography information (netCDF variables ''buildings_0'' and ''orography_0'', respectively). |
882 | | ''orography_0(y,x)'' is an optional variable, comprising rastered orography-height information in m. |
883 | | ''buildings_0'' can be available in two general modes, distinguished by the variable's attribute ''lod''. \\\\ |
884 | | 1) If ''lod'' = 1, ''buildings_0(y,x)'' comprises rastered 2-D floating-point building / topography height information in m, or \\ |
885 | | 2) if ''lod'' = 2, ''buildings_0(z,y,x)'' comprises rastered 3-D integer building / topography information for each grid point. This case, ''buildings_0'' at the respective grid point is either 1 if the grid point belongs to a building, or is 0 if the grid point belongs to the atmosphere. Topography information need to be given up to the highest grid level where topography occurs. It is not required to provide topography information up to the model top. The 2) method is only required if overhanging building structures should be considered. Moreover, in this case, orography information is not considered so far. \\ |
