AUSTAL View is a graphical user interface for the official German Federal Environmental Agency air dispersion model, AUSTAL2000.
The AUSTAL2000 model was developed according to Germany's air pollution control regulation TALuft (Technical Instructions on Air Quality).
AUSTAL2000 is a Lagrangian particle tracking air dispersion model that contains its own diagnostic wind field model (TALdia). The model takes into account the influence of topography on the wind field and therefore on the dispersion of pollutants.
