The UNBC Air Quality Map provides hourly PM2.5 observations. It shows the Canadian Air Quality Health Index Plus (AQHI+) values, which are also used by the BCCDC and the BC Air Quality Website. Data on this map are corrected against data from regulatory monitors using a formula developed by the University of Northern BC and Environment and Climate Change Canada, and are therefore the most reliable data available. Learn more about data correction here. Click the map above to see real-time air quality data.
Neighbourhood Sensor Network
The CVRD has worked with partners to establish a neighbourhood sensor network. Sensors for the network were established in collaboration with the School District, the BC Ministry of Environment and community stewards. Real time air quality readings can be found in various neighbourhoods by zooming into the Cowichan Region on the UNBC Air Quality Map.
Provincial Air Quality Monitors
The BC government maintains PM2.5 sensors at 3 locations in the Cowichan region. The data can be found at the BC Air Quality page under Current PM2.5 Data.
