I am Helge R. Olesen, senior advisor at the Department of Environmental Science, Aarhus University, Denmark. I contribute to Wikipedia in the field of atmospheric dispersion modelling.
I am chairman of the initiative on Harmonisation within Atmospheric Dispersion Modelling for Regulatory Purposes.
This initiative organises a series of international conferences on atmospheric dispersion modelling - see www.harmo.org for information on the conferences, providing access to papers presented at all conferences since 2001.
I am founder of Wiki on atmospheric dispersion modelling, http://atmosphericdispersion.wikia.com/
Note on my affiliation Until July 2011 my affiliation was the National Environmental Research Institute, Denmark. As of July 1, 2011 all research departments at the National Environmental Research Institute have become integrated in institutes at Aarhus University. Thus, the staff of the former Department of Atmospheric Environment - where I worked - have been transferred to the new Department for Environmental Science at Aarhus University.
