National Air Pollution Surveillance Network - Data

The National Air Pollution Surveillance Network has a Canada-wide database of criteria air contaminants from the early 1970s to the present for designated National Air Pollution Surveillance Network sites, as well as provincial, territorial and other sites. Trace contaminants are also monitored at several stations in the network and analyzed by the air quality research laboratory at River Road.

Data is available upon request by email to RNSPA-NAPSINFO@ec.gc.ca
