The Richards-Gebaur South air monitor sits on land that once housed the Richards-Gebaur Air Force Base, named after two Kansas City area veterans. The air monitoring station is located upwind of the Kansas City metropolitan statistical area, so it helps determine ozone and PM2.5 concentrations in the region — usually before gusts of wind enter the Kansas City metropolitan area.
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).
