The Lane Regional Air Protection Agency (LRAPA) was established in 1968 to achieve and maintain clean air in Lane County, Oregon.

LRAPA has eight regulatory-grade air monitoring stations and over 90 commercial-grade particulate matter sensors throughout Lane County. These air monitoring stations collect air samples and report the data from their respective locations. Information from these stations is used to assess levels of air pollution, identify air quality trends, and support the implementation of air pollution prevention strategies.

As a result of decades of work and technological advances, Lane County benefits from good air quality the majority of the year. There are days when air quality fails to meet health-based standards. In the summer, this usually occurs when smoke intrusions from wildfires move into the county. During the winter, smoke from fireplaces and wood stoves burning inefficiently can degrade air quality during prolonged periods of stagnant air.

Understanding the Air Quality Index (AQI)

The current air quality is displayed above using the Air Quality Index (AQI). As seen in the table below, the AQI is a numbered and color coded way to report the daily air quality. The AQI is not a specific unit of measurement, rather it is scaled indication of general air quality. The AQI in Lane county is calculated for two major pollutants regulated by the Clean Air Act: ground-level ozone and particulate matter (PM2.5). For each of these pollutants the US EPA has established national air quality standards to protect public health.
Air Quality Index (AQI) Values Levels of Health Concern Colors
When the AQI is in this range: ..air quality conditions are: ...as symbolized by this color:
0-50 Good Green
51-100 Moderate Yellow
101-150 Unhealthy for Sensitive Groups Orange
151 to 200 Unhealthy Red
201 to 300 Very Unhealthy Purple
301 to 500 Hazardous Maroon
The current AQI represents the amount of pollution in the air using a weighted average of the last twelve hours and is a forecast of the current days average pollution level. The actual AQI level for any given day is based on the 24 hour average of the pollution levels for that day.

To translate the AQI into specific measurements of PM 2.5 or Ozone, please use the AQI to Concentration Calculator.
