Air Quality Monitoring Data

Fairbanks Carbon Monoxide (CO)

The Fairbanks area is a limited maintenance area for CO. The charts below show historical data from monitors in the Fairbanks area. The Alaska Air Monitoring Plan contains more information about these monitors.

Note: The vertical axis of these charts extends to 10 ppm.

NAAQS
National Ambient Air Quality Standard - A health-based air quality standard set by EPA based on a review of available scientific information. NAAQS exist for criteria pollutants including Particulate Matter (PM2.5 and PM10), Carbon Monoxide (CO), Sulfur Dioxide (SO2), Nitrogen Dioxide (NO2), Ozone(O3), and Lead(Pb).
EPA's NAAQS Webpage
Concentration, µg/m3
The amount of PM2.5 suspended in the air with units of micrograms(one-millionth of a gram) per cubic meter
Exceedance
A day when the 24-hour measured concentration of PM2.5 exceeds the NAAQS.
98th Percentile
The daily value out of a year of PM2.5 monitoring data below which 98 percent of all daily values fall. 40 CFR 50 Appendix N - see section 4.5(a) (PDF)
24-hour Design Value (DV)
A three-year average of the 98th percentile value. An area is in violation of the NAAQS when the Design Values is greater than the 24-hour NAAQS for PM2.5, which is currently set at 35 µg/m340 CFR 50 Appendix N - see section 4.5(b) (PDF)
Clean Data Year
A year when the 98th percentile value is less than the NAAQS.
Exceptional Events
Unusual or naturally occurring events that can affect air quality but are not reasonably controllable.
EPA's Exceptional Events Webpage
DEC's Exceptional Events Webpage
Compliance with PM2.5 NAAQS
24-Hour: 98th percentile, averaged over 3 years, must be below the standardAnnual: Annual arithmetic mean, averaged over 3 years, must be below the standard. 40 CFR 50 Appendix N - see sections 4.1 and 4.2 (PDF)
