This dataset makes historical air quality data accessible for various parameters at Calgary monitoring stations. The data is collected by the Calgary Regional Airshed and Alberta Environment and Parks groups. The data is collected via a web service provided by the Alberta Environmental Monitoring, Evaluation & Reporting Agency (AEMERA). AEMERA provides access to historical air quality data at its air quality stations.
Prior to 2011, Alberta used the US EPA's Air Quality Index calculation method, which produces an index ranging from 0 to 500 (with <100 corresponding to "good" (0-50) or "moderate" (51-100) air quality). Since 2011, Alberta has used the Canadian 10-point Air Quality Health Index scale, with calculations augmented to include additional pollutants. Further information on the AQHI calculation is available at: http://aep.alberta.ca/air/air-quality-health-index/AQHI-calculation.aspx
