The air quality warnings in Iowa due to the smoke from Canadian wildfires were cleared by midday Tuesday. Air quality ratings indicate when air is unhealthy for sensitive groups, like people with asthma. Todd Russell works in the Air Monitoring program for the Iowa Department of Natural Resources, and he says even he was surprised to learn smoke was drifting over the state given our wet spring, but air quality maps clearly show the origins.
