*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.

When the AQI is in this range:	..air quality conditions are:	*...as symbolized by this color:*
Air Quality Index (AQI) Values	Levels of Health Concern	Colors
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 and can be found here or by selecting the "AQI for the Last 45 Days" link on the left side of this page.
