WinAUSTAL Pro - Version AUSTAL3 -Air Pollutant Dispersion Calculation

The Lagrangian dispersion models such as Austal3 are not subject to the limitations of the Gaussian dispersion models. To model real conditions complex terrain, buildings as well spatially inhomogeneous and time variable wind/turbulence fields can be handled with Lagrangian dispersion models.

• Project-based, intuitive, layer-based user interface in German, English and recently in Turkish
• The dispersion model AUSTAL3  can be controlled directly and completely from WinAUSTAL.
• Everything in view by multi-window control and history list
• Gauss-Kruger coordinate system and UTM coordinate system selectable
• The AUSTAL.txt can displayed and edited in text- and graphic mode
• Easy digitization of sources, monitor points, individual buildings and building inventories
• Add and visualizing of extra layers (SHP, DXF, MIF, DBF, CSV)
• Automated creation of building grids for complex building structures
• Import (DBF, CSV) of meteorological data (WS, WD and global radiation, ari pressure or cloud cover) to create dispersion category statistics
• View, edit and convert of dispersion category statistics
• Import of building inventories in ESRI Shape format
• Geo-referencing of digital maps (TIF, BMP, JPG, EMF, WMF)
• Layout of maps / calculation results (including north arrow, scale bar and legend)
• Export of all representations or layers in ESRI Shape format or as a graphic file (BMP, JPG)
• Character set of AUSTAL3 adjustable (ISO-8859-1 or UTF8)
• Easy creation and editing of variable time series for source emissions
• Batch processing of AUSTAL3 calculations possible
• Calculation of wind field libraries (without starting dispersion caluclation)
• Calculation and presentation of evaluation areas for GIRL
• Predefined and own legends selectable for presentation of results
• Multiplication, addition or division of 3D AUSTAL3 result files (DMNA format) by selecting a layer and in consideration of factors and / or exponents
• Representation of concentration fields as a horizontal section with freely definable legend on geo-referenced maps
• Representation of wind fields (vectors) as a horizontal section with freely definable legend on geo-referenced maps
• Representation of time series to monitor concentration points for a quick overview of the most heavily loaded hours in the calculation period
• Export of all calculation results into ESRI Shape files (point or polygon) optional under consideration of factors and addition of background concentration
• WinAUSTAL is tested on Windows 11

• AUSTAL3 is the official dispersion model for permitting procedures of technical plants in Germany. It has been developed by Ingenieurbüro Janicke, Dunum on behalf of the German Federal Environmental Agency and provided for free use under GNU license.
• 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.
• AUSTAL3 is a Lagrangian particle model (according to guideline VDI 3945 / 3), allowing to calculate as well concentration time series as statistical parameters.
• AUSTAL3 needs as input a meteorological time series "AKTerm" or the statistics for wind speed, wind direction and dispersion category.
• AUSTAL3 can treat point, line and area sources.
• AUSTAL3 contains a diagnostic wind model in order to treat the effects of complex terrain and buildings.
• AUSTAL3 implemented the odor module. Thus it is possible to calculate odor hour frequencies.
