NEWKIRK IMPROVE Air Monitoring Station, Kay County, Oklahoma

NEWKIRK IMPROVE is an air monitoring station located north of Newkirk, Oklahoma, along Highway 77. Operated by the Cherokee Nation, this station is part of the broader network of air quality monitoring facilities in the United States. It serves the rural area of Kay County, contributing to the understanding of local air pollution levels. The station operates under the regulatory framework of the US EPA Air Quality System (AQS), which sets standards for criteria pollutants such as ozone, particulate matter, and nitrogen dioxide. While specific parameters measured at this site are not detailed, typical rural monitoring stations track a subset of these pollutants to assess background air quality. The station's last reported sample date is October 2020, indicating ongoing data collection. This facility plays a key role in monitoring air quality in a region influenced by agricultural activities and transportation. Data from NEWKIRK IMPROVE helps inform public health advisories and supports compliance with National Ambient Air Quality Standards (NAAQS). Its operation by the Cherokee Nation underscores the involvement of tribal authorities in environmental monitoring.

The station is situated in a rural area of north-central Oklahoma, where air quality is primarily affected by agricultural emissions, dust, and vehicle traffic. Monitoring in such locations helps establish background concentrations and detect regional transport of pollutants. The facility's data contributes to the EPA's AQS network, which supports regulatory compliance and research on air quality trends.
