About Air Quality Research

Environment Canada's air quality researchers make significant contributions to the understanding of a variety of air pollution problems, in Canada and abroad.

Environment Canada works to develop, apply and provide world-class unbiased, relevant and scientifically sound and timely knowledge, data and information on atmospheric chemistry and physics. This work supports the development of policies and regulations, and high quality environmental services to Canadians.

Environment Canada achieves this by:

  • Conducting research and measuring the physical and chemical processes that determine the chemistry of the atmosphere;
  • Undertaking air quality monitoring and measuring techniques;
  • Measuring and analyzing exhaust emissions, from both mobile and stationary sources;
  • Conducting research and generating information, data and techniques to facilitate the assessment and manage of risk associated with atmospheric releases of chemical substances in commercial use;
  • Conducting stratospheric pollution research and satellite remote sensing to study the photochemistry of ozone and assess ozone depletion;
  • Developing and using ground-based observing technology such as the Brewer spectrophotometer to research ozone, nitrogen dioxide, and the ultraviolet ground-level solar spectrum;
  • Developing tools and techniques to detect and characterize airborne particulate pollution and to contribute to an understanding of its dispersion and motion in the atmosphere; and
  • Conducting modelling research on the transport, transformation and deposition of pollutants in the atmosphere.
