Austal2000 is an
atmospheric dispersion model for simulating the dispersion of air pollutants in the ambient
atmosphere
An atmosphere () is a layer of gas or layers of gases that envelop a planet, and is held in place by the gravity of the planetary body. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. A s ...

in Dunum, Germany under contract to the Federal Ministry for Environment, Nature Conservation and Nuclear Safety.
Although not named in the TA Luft, 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.
Description
It simulates the dispersion of air pollutants by utilizing a
random walk
In mathematics, a random walk is a random process that describes a path that consists of a succession of random steps on some mathematical space.
An elementary example of a random walk is the random walk on the integer number line \mathbb Z ...
process (
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.

Austal2000G is a similar model for simulating the dispersion of odours and it was also developed by Ingenieurbüro Janicke. The development of Austal 2000G was financed by three German states: Niedersachsen, Nordrhein-Westfalen and Baden-Württemberg.
