Welcome to our Live Air Quality Data feed, where you can access near real time hourly readings from any one of our nine continuous monitoring stations. You can find multiple substances for one station or one substance for multiple stations. Dates and times are adjustable and you can compare readings to provincial objectives. We monitor for 19 substances that are known to be emitted by various sources in the Airshed. Read a summary of Alberta Ambient Air Quality Objectives for the substances we monitor.
Things to Remember:
- The data is recorded in Mountain Standard Time. Data is generally indicative of ambient conditions but it is raw data. Our quality controls validate the information and then it is stored in a Government of Alberta Air Data Warehouse. The Air Quality Health Index is calculated by the Government of Alberta and records are stored on-line for one year.
- If there are data breaks in our live feed, it simply means data was not recorded for that time period. Often, this is due to scheduled equipment maintenance or calibrations being made at that time.
- We track 19 substances and eight meteorological conditions but not from all stations. Ammonia, for example, is tracked at three stations and nitrogen dioxide at all 10 stations. For a complete list of stations and what substances they monitor, click here.
- You can’t compare substances that have competing measurement units. For example, ppb (parts per billion) versus ppm (parts per million). When this conflict occurs, you will see the pop-up “The Y-axis can only have one scale”.
- From time to time data points may be removed after they have been found to be in error due to instrument malfunction.
- Negative numbers that may appear have not yet been referenced to the daily zero check.
