Preface
Worldwide air pollution remains a threat to human health and the environment.
Despite the efforts over the last decades, especially in the USA and Europe, many
of the air pollutant concentrations are still too high, leading to persistent air quality
problems. “Air pollution is still responsible for more than 400.000 premature deaths
in Europe each year,” states the European Environment Agency.
Since 1969, scientists and policy makers from all over the world meet to discuss
these problems at the International Technical Meeting on Air Pollution Modeling
and its Application (ITM), using air quality models to study the atmospheric
transport, chemistry, impacts and sources of air pollution, its effect on human
health, and its interaction with climate change. Their results, new insights, and
discussions are very much appreciated by regulators and policy makers and help
them to underpin national and international abatement programs and protocols.
This volume contains the abstracts and papers presented at the 36th ITM, held in
Ottawa, Canada, from May 14–18, 2018. The 36th ITM was organized by Carleton
University and Environment and Climate Change Canada (Host Country) and
VITO in Belgium (Pilot Country) in conjunction with the annual WMO-GURME
meeting. Key topics presented at this ITM correspond to the sections in this book
and include: regional and intercontinental modeling; local- and urban-scale modeling; emission modeling and processing; data assimilation and air quality forecasting; model assessment and verification; aerosols in the atmosphere; modeling
air pollution in a changing climate; and air quality effects on human health and
ecology.
The ITM was attended by 131 participants representing 22 countries. Keynotes
were presented by Randall Martin, Dalhousie University (air quality effects on
human health), Arlene Fiore, Columbia University (modeling air pollution in a
changing climate), Luisa T. Molina, Massachusetts Institute of Technology (localand urban-scale modeling), and Richard Burnett, Health Canada and University of
Washington (air quality effects on human health).
On behalf of the ITM Scientific Committee and as organizers and editors, we
would like to thank all the participants who contributed to the success of the
meeting and its high scientific level. We especially recognize the organizational and
