This dataset makes historical air quality data accessible for various parameters at Calgary monitoring stations. The data is collected by the Calgary Region Airshed Zone and submitted to Alberta Environment and Parks (AEP). The data is delivered to the airdata warehouse, a central repository for Alberta's ambient air quality data via a web service provided by AEP. In this way, AEP provides access to quality controlled historical air quality data at its air quality stations.
In addition to air quality monitoring data, an Air Quality Health Index (AQHI) is calculated hourly at certain monitoring stations. The AQHI is a simple way to interpret air quality conditions: it provides a number from 1 to 10+ which indicates the relative health risk associated with local air quality. The higher the number, the greater the health risk. Further information on the AQHI calculation is available at: https://www.alberta.ca/air-quality-health-index--calculation.aspx

This is a measure of the raw rain data accumulated at various rain gauges throughout the City during the rain season, which typically runs from May 1- Sep 30. Readings are taken at 5 minute intervals, and updated daily. This data is QA/QC'd on an annual basis at the end of the calendar year at which time some adjustments may be made to the data. Users should keep in mind that data viewed before March 31 of the following year should be considered in a ‘raw’ state and may be subject to change. Fully QAQC'd data is then made available in the Historical Rainfall dataset.
