Historical Air Quality

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

本数据集开放了卡尔加里（Calgary）监测站各类参数的历史空气质量数据访问权限。该数据由卡尔加里区域空气流域区（Calgary Region Airshed Zone）采集，并提交至阿尔伯塔环境与公园厅（Alberta Environment and Parks，AEP）。数据经由AEP提供的Web服务，传输至阿尔伯塔省环境空气质量数据的中央存储库——空气质量数据仓库（airdata warehouse）。借此机制，AEP可为用户提供其各空气质量监测站经质量管控的历史空气质量数据访问服务。除空气质量监测数据外，部分监测站还会每小时计算空气质量健康指数（Air Quality Health Index，AQHI）。AQHI是解读本地空气质量状况的简易工具：其给出1至10+的数值，用以表征与本地空气质量相关的相对健康风险。数值越高，代表健康风险越高。有关AQHI计算方法的更多信息，可通过以下链接查阅：https://www.alberta.ca/air-quality-health-index--calculation.aspx
