The Liberty air monitoring station helps characterize exposure to ground-level ozone and fine particulate matter of a segment of the Kansas City metropolitan statistical area. In the past, the station has monitored other pollutants; for example, it monitored nitrogen dioxide from 1982 to 2010.
Pollutants
Ozone Pollutant
The primary National Ambient Air Quality Standard (NAAQS) for ozone is 0.070 parts per million (ppm) averaged over eight hours (annual fourth-highest daily maximum 8-hour concentration, averaged over three years). The federal ozone monitoring season runs from March 1 to Oct. 31.

Fine Particulate Matter (PM 2.5)
The primary National Ambient Air Quality Standards (NAAQS), based on health effects, for fine particulate matter smaller than 2.5 micrometers in diameter, PM2.5, is 35 micrograms per cubic meter of air (μg/m3) averaged over 24 hours (98th percentile, averaged over three years) and 12 μg/m3 annual average (averaged over three years).
