LAT/LONG POINT IS OF SAMPLING INLET Air Monitoring Station, Baltimore, Maryland

LAT/LONG POINT IS OF SAMPLING INLET is an operational air monitoring station located at Clifton Park on Rose Street in Baltimore, Maryland, United States. The station is managed by the Maryland Department of the Environment and contributes to the national ambient air quality monitoring network under the US EPA Air Quality System (AQS). As a fixed-site monitor, it provides continuous data on pollutant concentrations to support regulatory compliance and public health assessments. The station operates within the framework of the US Clean Air Act, which mandates monitoring of criteria pollutants such as ozone, particulate matter, carbon monoxide, sulfur dioxide, nitrogen dioxide, and lead. While specific parameters measured at this site are not detailed, typical urban stations in Baltimore track ozone and PM2.5 due to local air quality challenges. The Maryland Department of the Environment follows EPA siting criteria to ensure data representativeness for population exposure and regional transport studies. This monitoring station plays a key role in characterizing air quality in Baltimore, a city with historical industrial emissions and traffic-related pollution. Data from this site supports the State Implementation Plan for attaining National Ambient Air Quality Standards and informs public health advisories. The station's long-term operation contributes to trend analysis and evaluation of emission reduction strategies in the Mid-Atlantic region.

Baltimore's air quality is influenced by a mix of local sources, including vehicle emissions, industrial facilities, and port activities, as well as regional transport from upwind areas. The city is designated as a moderate nonattainment area for the 2015 ozone standard, necessitating robust monitoring to track progress. This station's location in Clifton Park provides a representative urban background site, capturing population exposure. Monitoring data supports the Maryland Department of the Environment's efforts to assess compliance with EPA standards and to develop effective control measures.
