### Calculation according to

Dispersion calculations according to

When calculating according VDI 3782 part 1 / 2001, the 9 TA Luft wind velocity categories are taken into account, as well as a new parameter set for 180 instead of 150 Meters in the dispersion parameter calculation (F, f, G, g).

### Calculation accuracy

These settings influence the calculation accuracy and therefore the calculation time and the needed disk space. (more)

### Store vertical distribution

Characteristics for receptor points of different heights or graphical cross-sections through the waste gas plume are possible with stored vertical distribution only. (more)

### Rise according to VDI 3784 part 2 {With the option cooling tower only}

The calculation of the plume rise will be performed with the Model

### Use Alternative Dispersion Parameter

Dispersion parameter deviating from the guideline can be used. The accompanying form can be opened with this button. Parameters will appear on the print-out of characteristics calculations. (more)

### Anemometer height [m]

The anemometer height is to be entered between 3 m and 50 m. The knowledge of the anemometer height (in rare cases deviating from 10 m) is required for the correlation between the vertical wind profile and a wind velocity class. For very low sources VDI 3782 defines a constant wind velocity from a height of 10m. As within the context of

### Receptor point height [m]

Set the receptor point height between 0 m and 100 m. For a certain receptor point height, concentrations are always entered. If a concentration array without vertical distribution is calculated, the receptor point height is the only available height during the characteristic calculation (usually the receptor point height is 1.5 m). (more)

### Calculation for dispersion category

The concentration area calculation can be limited to a dispersion category. Therefore the calculation of the characteristic statistic is also limited to this category. (more)

### Calculation of wind velocity (1-9 and for VDI 3782 part 1 1992, 1-15)

The concentration area calculation can be limited to a wind velocity category. Therefore the calculation of the characteristic statistic is also limited to this category. (more)

### Inversion heights

Inversion height values can be entered between 250 and 1500. Dispersion calculations according to
