WinAUSTAL Pro

... AUSTAL for Windows

WinAUSTAL is a user-friendly interface for creating and visualizing the AUSTAL input file and for graphically displaying the calculation results. WinAUSTAL enables the user to quickly and conveniently analyze plants and projects with regard to the dispersion of air pollutants in accordance with the amended TA Luft.

The new version of the Technical Instructions on Air Quality Control (TA Luft), the central set of regulations for air pollution control with regard to plants requiring approval under immission control law in Germany, comes into force on December 1, 2021. It was published in issue no. 48 - 54 of the Joint Ministerial Gazette on September 14, 2021.

Lagrangian dispersion models such as AUSTAL are not subject to the limitations of Gaussian dispersion models. Complex topographies, buildings and spatially inhomogeneous, temporally variable wind and turbulence fields, i.e. realistic conditions, can be handled with Lagrangian dispersion models.

The AUSTAL program was developed by Ingenieurbüro Janicke on behalf of the Federal Environment Agency in Berlin. AUSTAL is freely available at www.umweltbundesamt.de.

AUSTAL

AUSTAL is a dispersion model that represents an exemplary implementation of the annex “Dispersion calculation” of the “Technical Instructions on Air Quality Control (TA Luft)”.
AUSTAL (starting with version 3) refers to TA Luft 2021 and is the successor to AUSTAL2000 (ending with version 2), which refers to TA Luft 2002.
AUSTAL is a Lagrangian particle model (according to guideline VDI 3945 sheet 3), which enables the user to perform both statistical and time series calculations.
AUSTAL requires as input data a meteorological time series AKTerm or a dispersion class statistic AKS, if necessary a file with a digital terrain model and an input file with all necessary input parameters for the dispersion calculation.
AUSTAL can calculate odor hour frequencies.
AUSTAL has implemented the diagnostic wind field model TALdia. This makes it possible to calculate flow fields taking into account topography (terrain flow) and buildings (building flow).
