On 16 September 2026, from 14:00 to 16:00 (online), we will host a free webinar dedicated to a topic that is of growing interest worldwide: the validation of odour dispersion models using the grid method defined in EN 16841‑1.

   Consultants run odour dispersion models around the world, but because odour concentration is difficult to measure reliably in ambient air, there is no practical way to know whether the model predictions are right or wrong. With the approach developed and applied in Germany, Austria and Switzerland, along the last over 40 years, it is possible to check the performance of a model and verify whether an odour dispersion assessment has been done correctly against field measurements.
