PEI Air Monitoring Data Hub

What is the PEI Air Monitoring Hub?

The PEI Air Monitoring Data Hub is a website where you can find ambient air quality data and annual PEI Air Quality Reports.  The data is presented in an easy-to-use dashboard type format with interactive maps and graphs. 

Where does the data come from?

The data comes from real-time monitoring equipment that continuously collects data at three sites; Wellington, Charlottetown and Southampton. At each location ground-level ozone (O3), nitrogen oxides (NOX) and fine particulate matter, or PM2.5 (particles that have a mean diameter of 2.5 microns or less) are monitored. In Charlottetown, sulphur dioxide (SO2) is also monitored. Mercury in ambient air and precipitation monitoring are monitored at the Southampton station. 

The operation of the monitoring is accomplished through a partnership with Environment and Climate Change Canada's National Air Pollution Surveillance Program (NAPS).

What type of information is available?

A variety of information is available, such as:

  • O3, NOX , SO2, and PM2.5 real-time ambient air monitoring data 
  • AQHI (Air Quality Health Index) - real-time values and forecasts calculated by Environment and Climate Change Canada
  • Mercury in ambient air real-time data
  • Precipitation monitoring data (pH)
  • Air Management Levels for PEI
  • Canadian Ambient Air Quality Standards for PEI
  • Wildfire smoke forecast maps (Environment and Climate Change Canada)
  • PEI Air Quality Reports 

How often is the data updated?

It depends. Some of the datasets are updated hourly or less, while others are updated annually.
