An air pollution source.

AUSTAL2000 is an air pollution dispersion model for simulating the dispersion of air pollutants in the ambient atmosphere.[1][2][3] It was developed by Ingenieurbüro Janick[4] in Dunum, Germany under contract to the Federal Environment Agency of Germany. Although not named in the TA Luft,[note 1] it is the reference dispersion model accepted as being in compliance with the requirements of Annex 3 of the TA Luft and the pertinent VDI Guidelines.[note 2]

Description

It simulates the dispersion of air pollutants by utilizing a Lagrangian simulation model and it has capabilities for building effects, complex terrain, pollutant plume depletion by wet or dry deposition, and first order chemical reactions. It is available for download on the Internet free of cost.[5]

AUSTAL2000G is a similar model for simulating the dispersion of odors and it was also developed by Ingenieurbüro Janicke. The development of AUSTAL2000G was financed by three German states: Lower Saxony (German: Niedersachsen), North Rhine-Westphalia (German: Nordrhein-Westfalen) and Baden Württenberg.

Notes

  1. Germany has a well known air pollution control regulation titled "Technical Instructions on Air Quality Control" (Technische Anleitung zur Reinhaltung der Luft) and commonly referred to as the TA Luft.
  2. Verein Deutscher Ingenieure (VDI) (English: Association of German Engineers) is today the largest engineering association Europe. The role of the VDI in Germany is comparable to that of the American Society of Mechanical Engineers (ASME) in the United States.
