*LRAPA did not create this map or does it vouch for its accuracy, or guarantee that it is the most recent map data available. The map should be used only for determining the current and forecasted air quality in your general geographical area and should not be used as a reference for determining locations of property or their boundaries.

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.

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 and can be found here or by selecting the "AQI for the Last 45 Days" link on the left side of this page.
