The 24-h average of meteorological conditions during the smoke episode and typical days. All indoor sensors were aggregated in the indoor facility calculations. Outdoor sensors are the rooftop air quality egg, Clark Drive, Kensington Park, and Vancouver International Airport (YVR) which are part of the National Air Pollution Surveillance (NAPS) network.
