Background of the initiative
In 1991, a European initiative was launched for increased cooperation and standardisation of atmospheric dispersion models for regulatory purposes. A "new generation" of models is emerging with physically more justifiable parametrisations of dispersion processes. A need was felt for these new models to be developed in a well-organized manner and turned into practical, generally accepted tools fit for the various needs of decision-makers. On this background it was decided to organize a series of workshops to promote the use of new-generation models within atmospheric dispersion modelling, and in general improve "modelling culture". This series of activities has now been going on for about 10 years.
See also: "Ten years of Harmonisation activities: Past, present and future". Paper presented at the 7th Harmonisation conference in May 2001.
The initiative is managed by a steering committee.
Workshops and conferences
One central activity of the initiative has been a series of workshops and conferences.
Information on each of the meetings since 1992 is available through
the overview page:
List of
Harmonisation conferences and workshops
For all workshops and
conferences there is information on the papers presented. For some of
the workshops/conferences, also information on the outcome of the
meetings and some full text papers are available.
Proceedings of the Harmonisation workshops and conferences
For the past workshops and conferences, lists of titles and authors of papers
presented are available.
For all conferences since 2001, the proceedings are freely available on-line.
Furthermore, full-lenght versions of papers from the conferences have been published in Special issues of the
International Journal of Environment and Pollution.

The links here will take you directly to the on-line proceedings from, respectively the conferences in Crete, October 2005 and Cambridge, July 2007. Many PowerPoint presentations from the conferences are also available.
International conference in Cavtat, Croatia (2008)
The next conference - the 12th International conference on
Harmonisation within Atmospheric Dispersion Modelling for
Regulatory Purposes - will take place in Cavtat, Croatia, October 6-9, 2008.

"Model Validation Kit"
A central activity of the "Harmonisation" initiative, closely related to the conferences, is the distribution of the so-called Model Validation Kit.
The Model Validation Kit is intended to be used for evaluation of atmospheric dispersion models.
It is a collection of four field data sets as well as software for model evaluation.
The Kit is a practical tool intended to serve as a common frame of reference for model performance evaluation.
It addresses the classic problem of dispersion from a single point source.
During the series of Harmonisation conferences, many papers have referred to the Kit. The package was updated to Version 2.0 in October 2005.
An ASTM standard guide on model evaluation was published in November 2000. It represents an alternative approach to that of the Model Validation Kit. More info...
Activities related to the initiative. Tools for dispersion modelling.
You will find an annotated list of activities and tools which are somehow related to the initiative (e.g.
the e-mail discussion list AtmosphericDispersion, the Model Documentation System, various COST actions, the
web site Datasets for Atmospheric Modelling, a tool for model intercomparison etc. on a separate page:
