The Air Quality Health Index (AQHI) is a tool that measures air quality in your community and reports it on a scale from 1 to 10. Learn more about the AQHI and what the air quality around you means to your health by visiting Alberta Environment and Parks page.

Air quality information collected the previous hour becomes available about 15 minutes after the current hour. Information is available for the previous 45 days. Archived data (older than 45 days) is available at the Airdata Warehouse (formally CASA Data Warehouse).

Monitoring air quality

Monitoring stations measure the outdoor ambient air quality. Data from a number of stations, collected over time, are used to determine air quality in a particular area.Several different methods and techniques are used but continuous and passive monitoring equipment is commonly used in Alberta. All monitoring data undergoes quality control and quality assurance procedures. The data is posted to the Airdata Warehouse (Alberta Ambient Air Data Management System) website.

The Alberta monitoring network provides core information for the evaluation of long-term trends and inter-relationships of air quality in the province. Alberta Environment is responsible for conducting province-wide monitoring.

Alberta Airsheds

Alberta’s Airsheds provides leadership in support of healthy air quality for Albertans and the environment. They operate in local Alberta communities to monitor the quality of the air we breath. Data from Airshed monitoring stations contribute to the AQHI. which in turn can help you understand how current air quality can impact your health. Ten Airsheds formed in Alberta between 1996 and 2017. They now operate more than 70 air monitoring stations across the province in compliance with provincial and federal standards, including Alberta’s Air Monitoring Directive. Airsheds are a key partner with established regional networks for responding to local and regional air matters, and they participate in dozens of community education and outreach events each year. They are an important contributor to CASA’s work as airsheds regularly participate in our projects and other initiatives. For more information please see here.
