City of Calgary Historical Air Quality REST API v2.1

The City of Calgary Historical Air Quality API retrieves historical air quality data collected by the Calgary Region Airshed Zone and submitted to Alberta Environment and Parks (AEP). In addition to air quality monitoring data, an Air Quality Health Index (AQHI) is calculated hourly at certain monitoring stations, providing a number from 1 to 10+ that indicates the relative health risk associated with local air quality.
