18 | | • LOD 0 requires a mean surface emission per day (in micromol/m2/d for gases and in kg/m2/d for particulate matter) for each desired species contained in the applied chemical mechanism together with a weight differing between main and side road emissions defined in the PALM Fortran namelist file (see [wiki:doc/app/par Fortran namelist file] and [wiki:doc/app/chemistry_parameters chemistry parameter list]). Furthermore, the street type classification provided by Open Street Map must be included in the PALM static driver (see [wiki:doc/app/iofiles/pids/static Static input file]) |

| 20 | To account for the temporal distribution of the parameterized traffic emissions a diurnal profile based on urban traffic counts is implemented to disaggregate the total emission of the different species to hourly values. Currently, the applied temporal profile is the same for all species and main and side roads. |

| 22 | Please note that LOD 0 is currently not applicable if the horizontal grid exceeds 10 to 15 m at maximum (depending on the width of the streets in the considered area). In this context, it must also be considered, that streets, which are only one grid point wide will probably be eliminated the topography filtering during runtime, i.e. emissions from steets which are only one grid point wiede will be supressed. |
