Odor model data

Odor model data form

TA Luft, VDI 3782 part 4

Select odor model according to VDI 3782 part 4 or the Factor-10-method.

Variance factor

Variance factor for the Factor-10-method


Select a model for the waste gas plume rise from the list.

Lower epsilon threshold

Variance threshold


In the guideline draft lambda=0.22 is set.

Time assessment threshold

For determination of the subjective odor frequency, brief odor influences will be increased to 100 %, if the time share exceeds the assessment threshold.

Sigma distance

Alternatively to calculate the dispersion parameters.
