Air Quality Data
Local air quality affects how we live and breathe and can change from day to day or even hour to hour. This section allows you to check levels of particulate matter (PM), and other common pollutants in the area.
Air Quality Network Map
The current air quality map is designed to help you plan your day by offering current air quality and general forecast information. The dot color indicates the latest air quality level for each monitoring station. Updated daily, the larger regions are also shaded colors, based on the day’s expected air quality forecast for that region.
Air Quality Sensor Map
This map is in beta testing and could experience technical difficulties. The purpose of this testing is to evaluate user experience and determine any unanticipated issues. The Sensor Map shows health-based and instantaneous particle pollution for the Agency’s four-county region.
Air Graphing Tool
This is a technical tool to help you look at and download raw air quality information across our region and other areas in Washington. Data from the last three months is considered preliminary and could be subject to change based on the quality assurance review.
