IMMISnet - Input Data

The input values in IMMISnet consist of the emission data for the sources under consideration, broken down into a number of polluter groups, and a climatological frequency distribution or a time series of meteorological parameters.
  • point sources
  • line sources (3 polluter groups)
  • areal sources (11 polluter groups)

The input values in IMMISnet consist of the emission data for the sources under consideration, broken down into a number of polluter groups, and a climatological frequency distribution or a time series of meteorological parameters. The model operates chronologically, i.e. the concentration contribution of all the sources considered are calculated for every hour of a year. The representative meteorological conditions for any particular hour are selected randomly from the climatological distribution of meteorological cases in a meteorological frequency distribution. The model determines hourly emissions from the annual emissions, using polluter-group-specific monthly, weekly and daily cycles. Up to 1000 arbitrary cycles can be individually linked to emission sources. 

Not only spatially but also temporally resolved emission data can be used for IMMISnet calculations of immissions.
