Parameter | Description |
---|---|
Model Name | AUSTAL |
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:
|
Output Type | The output type depends on the pollutant being modeled. Examples of possible outputs are:
|
Regulatory Status | Regulatory air dispersion model in Germany |
