About air indicators
Alberta’s Environmental Science Program monitors air quality across the province to better understand long-term changes over space and time. Explore the air indicators below to:
- learn more about why these indicators are important
- read about trends in Alberta’s air quality
- access additional data and resources
Other indicators
Explore air indicators
Fine particulate matter gets into the atmosphere due to human activities and natural emission sources like wildfire smoke.
The major sources of nitrogen dioxide are the burning of fuels for vehicles, home heating and industrial processes.
Ozone is a major component of smog, which is a mixture of gases and particles emitted into the air by human activities.
The major source of sulphur dioxide is the burning of sulphur-containing materials from industrial sources.
Wildfire smoke is a complex mixture of gases and particles and a major contributor to poor air quality.
Emanating from human and natural sources, ions travel via rain or snow and settle on the ground.
Use of indicators
The condition of environment indicators report on the current state and trends in Alberta’s air across the province. The air indicators were selected, prepared and reported on to meet this purpose. Other types of reporting, such as reporting against the Canadian Ambient Air Quality Standards (through Alberta’s Air Zone Reports) or compliance reporting near an industrial facility, have different purposes and requirements. Therefore, other reporting may use different data sets, data analysis methods, or time periods and are not directly comparable to the condition of environment reporting. For further details, visit:
Air monitoring
Alberta’s air is continually monitored to establish levels of air quality and the amount of air pollution deposited on Alberta’s land and water from airborne sources. To learn more about air monitoring, and to access data, see: Environmental monitoring.
Feature resource
The 5-year air quality and deposition monitoring, evaluation and reporting (MER) plan provides a roadmap and framework for the delivery of monitoring, evaluation and reporting activities being undertaken in partnership with stakeholders from 2021 to 2025. The plan contains 37 implementation items aimed at achieving 3 key outcomes including:
- providing the data and information required to manage air quality and deposition within environmental limits;
- reporting air quality information in real-time to inform the public and emergency response personnel about risk to human health; and
- sharing technical information on monitoring methods, and address current and emerging air quality and deposition issues.
