AUSTAL View 9.5

Lagrangian Particle Tracking Air Dispersion Model

  AUSTAL View Brochure

  Latest Release Notes

  Version 9.5: Release Notes

Overview

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.

Available AUSTAL View Modules

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.

Features

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 Earthâ„¢

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.

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.

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.



Technical Specifications

AUSTAL View is an interface for the AUSTAL2000 model. See below the technical specifications for this model:

Parameter Description
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
