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 are commonly used in Alberta. All monitoring data undergoes quality control and quality assurance procedures. The data is posted to the CASA Data 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.
