The data from these monitors are used to determine compliance with the Environmental Protection Agency’s National Ambient Air Quality Standards (NAAQS) for the criteria pollutants:
- carbon monoxide (CO)
- lead (Pb)
- nitrogen dioxide (NO2)
- ozone (O3)
- course particles (PM10)
- fine particles (PM2.5)
- sulfur dioxide (SO2)
