Monitoring Sites Map Air Quality Index (AQI)

Some of the features of this map may be limited on low resolution displays or when using the collapsed view. We recommend using the expanded map.

The bottom left corner of the map includes a legend, information on the monitoring network and explanation of map details.
Note: APCD real-time monitoring network is set to run on Mountain Standard Time (MST) year-round.
Sites that use filter samples (require laboratory analysis) are not uploaded in real time and therefore, are not shown on this map.
Air Quality Index (AQI) values are not validated. Please visit the EPA for validated data
