Ambient Air Quality Monitoring Program - Current Site Conditions
Some of NDEP's monitor data is presented in "near real-time" (hourly basis) on this page using the Air Quality Index (AQI). The AQI is an index for reporting air quality for various pollutants. The AQI is divided into six categories represented by a color and numerical range. For information on activity guidance during poor air quality events, please visit AirNow.gov or download the AirNow App.
