There are many initiatives related to dispersion modelling worldwide but there is no specific guideline for odour modelling. Modelling odours is complex and many of the guidelines on modelling published around the world fall short in treating this vector.
To date, there are already 52 professionals from Australia, Austria, Belgium, Brazil, Chile, China, Ecuador, France, India, Ireland, Italy, New Zealand, Peru, Spain, United Kingdom, USA and Qatar participating in this initiative. The group is quite heterogeneous as it is formed by scientists, consultants, representatives of public administrations and other stakeholders.
This is an initiative promoted by the Environmental International Society of Odour Managers and the website olores.org and it is led by the well-known experts Mr. Günther Schauberger and Ms. Jennifer Barclay.
Modelling odours often requires to forget about traditional dispersion modelling operating modes and to focus on exposure. Odours are perceived in seconds or minutes, not hours and this is key in calculating its impact on ambient air. Most odour incidents are generated during calm or very low wind speeds which do not facilitate the dispersion of an odour and that makes modelling challenging. Last, but not least, there is a need to investigate the role of Instrumental Odour Monitoring Systems (IOMS) on the evaluation of model performance.
Volunteers meet once per month via teleconference while the special task groups, of which there are 6 also meet every month. Each task group has between 5 and 10 members who are responsible for writing and reviewing individual sections within each task group. The task groups are as follows:
Volunteers are always more than welcome in this group, that it is expecting to have the first draft of the handbook after these 12 meetings. Interested may contact the Environmental International Society of Odour Managers, or the website
