Intensive Field Campaigns As A Means For Improving Scientific Knowledge To Address Urban Air Pollution

Air quality policies based on scientific and technical information are effective for controlling air pollution and protecting public health. Analysis of observations from periodic intensive field studies combined with updated emission inventories, air quality monitoring and numerical modeling can be used to address the causes that trigger air pollution and catalyze the design of cost-effective emissions control policies.Cutting-edge science is needed to address the air quality challenges posed by growing urbanization and climate change, emergent emission sources, and changes in emission profiles resulting from the implementation of advanced technology and regulatory measures.Cities should work towards building robust infrastructure and air quality management tools and rely on scientific research to attain cleaner air. The impacts of changes in emissions profiles and atmospheric chemistry under a changing climate need to be better understood and incorporated in the design of air quality management programs.
