IMMISluft - Output of concentrations

 

Model output
IMMISluft calculates the annual mean values for SO2,CO,CO2,CO2 (reported),NOx,NO2, particle matter (PM10, PM2,5, particle number), soot, HC, benzene, toluol, xylene, Pb, CH4, NH3, N2O, Benzo(A)pyren.

Calculation of statistical characteristics according to EU Council directives 
IMMISluft calculates 98%-percentiles and the following statistical characteristics according to EU Council directive 96/62/EG:

  • Exceeding probability of hourly limit value of NO2
    (There is no output of the 99,8%-percentile of hourly mean values since corresponding statistical error is in the order of magnitude of the limit value.)
  • 90,4%-percentile of PM10 daily mean value
  • Exceeding days of PM10
  • Highest sliding 8-hours mean value of CO

These values were calculated for two concentration points on both sides of the street. Concentration point is located 1.5 m above the ground and with a distance of 15% to the next building.
