Located in the Mingo National Wildlife Refuge, this air monitor provides data to help federal and state agencies assess regional haze. It's part of a program called Interagency Monitoring of Protected Visual Environments (IMPROVE), charged with improving visibility in national parks larger than 6,000 acres and national wilderness areas larger than 5,000 acres.
Of the approximately 155 national parks and wilderness areas in the program, two are in Missouri: Mingo National Wildlife Refuge and Hercules Glades.
Pollutants
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).
