This Alberta Official Statistic summarizes annual results of calculations of air quality index values as calculated by quality-assured and quality-controlled hourly ambient air quality data. It reports the number of hours of Poor and Very Poor air quality. It also includes an overview of the index, the substances that are used in its calculation, and the causes of poor air quality both in a general sense, and with specific reference to actual events in the years presented.

Usage Considerations
These statistics are based on results of a series of calculations performed on hourly data, and aggregated over a calendar year. As such, year-to-year differences should not be interpreted as indicators of trends in air quality and should not be extrapolated into the future. Results should not be taken as indicators of healthiness of living in the cities presented on.
Data obtained from CASA Data Warehouse.
Monitoring Stations Map: http://esrd.alberta.ca/focus/state-of-the-environment/air/monitoring-stations-ambient-air-quality-monitoring-in-alberta.aspx.
The linked map is created for a different purpose and may show more stations than are included in this data set, and may not show historical locations.
Calgary East was shut down in 2011 for relocation. Stations which have had PM2.5 monitoring technology upgraded since 2010 are: Medicine Hat and Fort Saskatchewan (2011), Fort McMurray AV (2012), Fort McMurray PM (2013). Stations which experienced reliability issues with the PM2.5 analyzer and failed to meet data completeness criteria are: Edmonton South and Lethbridge (2012), Medicine Hat (2013). The statistics for those stations are unavailable for those years. In some instances, stations have alternative names. Grande Prairie is also referred to as Henry Pirker, and Medicine Hat as Crescent Heights.
