Limitations Air quality data on this website are automatically polled from the Clean Air Sarnia and Area monitoring network and are intended for public awareness. Because the data is near-real time, they have not undergone complete quality control and quality assurance procedures, and so they may contain errors and are subject to change. The air quality data on this web page are considered “unverified data” and should not be used in published documents. Data integrity and validity may be affected by instrument malfunctions, telemetry connectivity, QA/QC requirements, instrument calibration times or power outages.
