HARMO - Initiative on Harmonisation within Atmospheric Dispersion Modelling for Regulatory Purposes

(From the Harmonisation Conference Website)

In 1991, a European initiative was launched for increased cooperation and standardization of atmospheric dispersion models for regulatory purposes. A "new generation" of models was emerging and the parametrizations of dispersion processes are even now continuously improving. A need was felt for 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 to improve the "modelling culture". The subsequent activities have now been going on for more than 20 years, and have developed to a series of successful international conferences.

This Harmonisation initiative also provides useful data bases on the Harmonisation website.

A historical overview of the “Harmo Initiative” was presented by Helge Olesen, former chairman, at the 18th Harmo Conference: Twenty-five years of Harmonisation Conferences – looking back and ahead.

A series of international conferences started after the first four workshops, becoming a recognized meeting place for model developers, model users, and stakeholders. Since the year 2000 the proceedings, consisting of 5-pages extended abstracts, are freely available online, subject to authors’ permission. Proceedings, presentations, and posters from the participants are available under the webpage of the relative conference listed here. Proceedings can also be found through a Google Scholar search.

Since 1994 full-length versions of selected papers from the conferences have been published in Special issues of the International Journal on Environment and Pollution (IJEP).
