v6 v7 10 10 Two modes require emission data from file. Gridded emission information can be provided in two LODs via a netCDF file (see also [https://palm.muk.uni-hannover.de/trac/wiki/doc/app/iofiles/pids]): 11 11 12 • LOD 1 files require annual emission information which are temporally disaggregated by PALM-4U using sector-specific standard time factors12 • LOD 1 files require gridded annual emission information which are temporally disaggregated by PALM-4U using sector-specific standard time factors 13 13 14 • LOD 2 files must contain pre-processed emission information that is already temporally disaggregated. At the moment hourly emission data is required. Other temporal intervals will be possible in later versions. IMPORTANT: In this mode the initial date of the simulation has to coincide with the first day for which emission values are available.14 • LOD 2 files must contain gridded pre-processed emission information that is already temporally disaggregated.

This option, named ’Parameterized’ mode, is currently only implemented for the traffic sector:
