AUSTAL View is a Lagrangian particle tracer model. Widely used in Germany, AUSTAL is capable of modeling complex wind fields and transient behavior. 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.
AUSTAL View is available in three versions (T, G, and TG) and an add-on module. See description below:
- AUSTAL View T: This version supports the TA Luft chemicals but does not support odor modeling (formerly AUSTAL View).
- AUSTAL View G: This version supports odor modeling but does not support the TA Luft chemicals (formerly ODOR View).
- AUSTAL View TG: This version supports all the TA Luft chemicals and odor modeling. This version combines the specialized AUSTAL View T and AUSTAL View G Versions (formerly AUSTAL View G+).
- Multi-Core Module: This module allows for the use of a multi-core (multi-processor) compatible model executables, and allows for the use of up to 8 multi-processors in a single-machine.
Integrated Graphical User Interface
Fully integrated interface combining easy to use graphical tools (e.g., sources, buildings, monitor points, and grid), seamless model run, and automated contouring and posting of results.
Powerful 3D Visualization
Complete 3D visualization of your entire modeling area. Sources, buildings, and modeling results are displayed in context with the surrounding terrain. Apply custom textures to buildings to further increase building realism. Create animation file (*.avi) of your 3D visualization.
Export to Google Earth
This exciting feature allows you to export your buildings, sources, receptors and contours into Google Earth giving you a more realistic image of where your pollutants will impact surrounding areas. learn more
Automated Download of Terrain Data (SRTM)
Advanced terrain processing capabilities available for several terrain data formats such as SRTM, USGS DEM, and XYZ.. Automated download of DEM and SRTM files from webGIS. SRTM3 data at 90m resolution is available worldwide. Automated conversion of these formats into the GridASCII data format required by the model.
Support for Several Base Map Formats
Visualizing your site in AUSTAL View is easy. Our full-featured support for a variety of image and base map formats allow you to design your model with confidence and view your results in context with your site. Supported base maps include: Bitmap, DLG, DXF, JPEG, LULC, MrSID, Shapefile, and TIFF/GeoTIFF.
Clear communication of your modeling and results are crucial to a successful project. AUSTAL View lets you impress with integrated report generation. 'Source Parameters', 'Monitor Point Results', and 'Maximum Calculation Results' are examples of reports automatically generated by AUSTAL View.
Met Data Visualization Tool - Windrose
Meteo View, which is included in the AUSTAL View package, allows you to create windrose plots for your meteorological data. The following formats are supported: AKT, AKTerm, AKS, series.dmna, zeitreihe.dmna. Options to manipulate the appearance of the windrose are available such as colors, petal size, grid sectors, etc.
Met Data Visualization Tool - Graph
Meteo View, which is included with the package, can also display bar graphs of the wind class and dispersion class frequency distribution and time series graph for wind speed, wind direction, and dispersion class.
German and English Versions Available
The AUSTAL View user interface, help files, and user's guides are available in German and English languages. The AUSTAL2000 model is also available in both languages.
AUSTAL View is an interface for the AUSTAL2000 model. See below the technical specifications for this model:
- Model Name: AUSTAL2000
- Developed By: German Federal Environmental Agency (UBA)
- Model Type: Lagrangian particle tracking air dispersion model
- Range: 100 times the source height. For example, for a stack height of 250 m a range of up to 25 km in radius is realistic.
- Source Types: Point, area, volume, line, cooling tower
- Pollutants and Emissions: Multi-pollutants can be model in a single run
- Emissions can be specified as constant or time-dependent
- Meteorology: Hourly meteorological data in AKT, AKTerm, and AKS formats are accepted by the model. The AKT, AKTerm format contain the hourly data for wind direction, wind speed, and stability class according to Klug/Manier. The AKS file contains the statistics of wind direction, wind velocity and dispersion class.
- Note: To support users without access to the above met file formats, AUSTAL View accepts a CSV file with the following hourly met data parameters: wind direction (deg), wind speed (m/s), and Monin-Obukhov Length (m).
- Terrain: Flat or Elevated. The model accepts terrain data in GridASCII format.
- Note: AUSTAL View accepts the following terrain data formats: GridASCII, XYZ, USGS DEM, and SRTM.
- Receptors: Single or nested grid, monitor points
- Other Options: Several additional model options are available, such as:
- Wind field around buildings and terrain
- Conversion of NO to NO2 (according to guideline VDI 3782 Part 1
- Variable source parameters (temperature, thermal flow, discharge velocity, and time scale
- Output Type: The output type depends on the pollutant being modeled. Examples of possible outputs are:
- annual mean of concentration,
- annual mean of deposition,
- maximum daily mean with nn exceedances,
- maximum hourly mean with nn exceedances,
- estimative of the statistical uncertainty, and
- time series of hourly concentration (only at monitor point locations)
- Regulatory Status: Regulatory air dispersion model in Germany
