Option APL enables the calculation, assessment and presentation of air pollutant distribution according to the relevant European guidelines. The results obtained can serve as the basis for action planning with regard to air pollution mitigation plans.

Option APL combines the user-friendly interface of CadnaA with the dispersion model AUSTAL2000, which is state-of-the-art air pollution modeling. Using the CadnaA PCSP technology (Program Controlled Segmented Processing) for full-automatic tiling, project distribution and processing on a network, the dispersion maps e.g. for traffic induced pollutants can be calculated for a project of any size.

• Calculation of air pollutant emission and immission in cities and urban areas
• Prognosis of air pollutant emission and immission to assess mitigation plans for road traffic
• Assessment of measures in the context of noise and air quality mitigation plans
• Prognosis of air pollutant emission and immission by industrial sources

• Maps showing air pollutant distribution for different components (e.g. PM₁₀ fine particles, NO₂, NO_X, SO₂, benzene)
• Meteorological time series with time dependant emission of point, line and area sources
• Standardized emission factors for road traffic
• Calculation of dispersion of pollutants with high resolution including the buildings and the terrain by using data from noise mapping
• Calculation of large areas using the powerful PCSP technology
• Grid arithmetic: superimposition of immission maps from several types of emission sources
• Calculation of plant-specific immission impact in the vicinity including the effect of thermal boost (also when emitted via cooling towers)
