Have you checked out Oregon Department of Environmental Quality's upgraded Air Quality Index yet? The color-coded tool reports how clean the air is at over 37 monitors around the state and provides information on potential health risks. The index now puts more data at your fingertips allowing you to view weather data, generate reports using historical data and more. And there's a mobile app now too! Just search for OregonAir in your smart phone's app store.
