Current developments in air pollution modelling are explored as a series of contributions from researchers at the forefront of their field. This newest contribution on air pollution modelling and its application is focused on local, urban, regional and intercontinental modelling; data assimilation and air quality forecasting; model assessment and evaluation; aerosol transformation. Additionally, this work also examines the relationship between air quality and human health and the effects of climate change on air quality. The work is comprised of selected papers presented at the 34th International Technical Meeting on Air Pollution Modelling and its Application held in Montpellier, France in 2015. The book is intended as reference material for students and professors interested in air pollution modelling at the graduate level as well as researchers and professionals involved in developing and utilizing air pollution models

This volume seeks to cover the latest scientific developments in the field of air pollution modeling. It contains papers and posters presented at the 26th NATO/CCMS International Technical Meeting on Air Pollution Modelling and Its Application held in Istanbul Technical University, Turkey, May 2003. Major topics covered include: the role of atmospheric models in air pollution policy and abatement strategies (air quality, risk assessment, emergency responses). Integrated regional modelling (local and urban effects, mesoscale phenomena, regional modelling, one and two way nesting, application of existing models). Global and long-range transport (synoptic, hemispheric & global scales, application of existing models). Aerosols as atmospheric contaminants (human exposure and health effects, direct and indirect climate effects, visibility reduction). New developments (microscale to global scale, new models, new extensions to existing models, inverse modelling, data assimilation). Model assessment and verification (model assessment, design of field experiments, use of on-site meteorological data, limits to predictability). Applications of new concepts in different regions of the world are also presented. The domain of the modeling covers all geographical sizes from global down to regional, local, urban and canyon sizes

In 1969 the North Atlantic Treaty Organization (NATO) established the Committee on Challenges of Modern Society (CCMS). The subject of air pollution was from the start, one of the priority problems under study within the framework of various pilot studies undertaken by this committee. The organization of a periodic conference dealing with air pollution modelling and its application has become one of the main activities within the pilot study relating to air pollution. These international conferences were successively organized by the United States (first five); Federal Republic of Germany (five); Belgium (five); The Netherlands (four) and Denmark (five). With this one Portugal takes over the duty. This volume contains the papers and poster abstracts presented at the NATO/CCMS International Technical Meeting on Air Pollution Modelling and Its Application held in Louvain-la-Neuve, Belgium, during 15-19 October 2001. This ITM was jointly organized by the University of Aveiro, Portugal (Pilot country) and by the Catholic University of Louvain, Belgium (host country). The ITM was attended by 78 participants representing 26 countries from Western and Eastern Europe, North and South America, Asia, Australia and Africa. The main topics of this ITM were : Role of Atmospheric Models in Air Pollution Policy and Abatement Strategies; Integrated Regional Modelling; Global and Long-Range Transport; Regional Air Pollution and Climate; New Developments; and Model Assessment and Verification.

The ITM conference series has always had a strong spirit of cooperation under the NATO/CCMS umbrella, and with the considerable interest fram Partner countries to participate in the ITM conferences, it provides an excellent opportunity to create ties between scientists. Whereas all previous ITM conferences have taken place in NATO countries, the 23rd ITM takes place in a Cooperative Partner country, Bulgaria, and is hosted by the National Institute of Meteorology and Hydrology, Bulgarian Academy of Sciences. This fact reflects a general wish for a closer connection and collaboration among scientists fram Partner and NATO countries. This volume contains the papers from the 23rd NATO/CCMS International Technical Meetings on Air Pollution Modelling and Its Application, being held September 28 - October 2, 1998, at Riviera Holiday Club, Varna, Bulgaria. It was attended by 120 participants from 30 countries. Thanks are due to all who made it possible to plan, carry through, and follow up the meeting, and to the participants who made the conference so successful.
