San Bernardino is an air monitoring station located at 24302 4th St., San Bernardino, California, within the South Coast Air Quality Management District (SCAQMD). The station is operational and contributes to the US EPA's Air Quality System (AQS) network, which monitors ambient air quality across the United States. As part of California's extensive monitoring infrastructure, it supports compliance with the Clean Air Act and state air quality standards. The station is operated by SCAQMD, the local regulatory agency responsible for air pollution control in the South Coast Air Basin. While specific parameters measured are not detailed, typical monitoring at such stations includes criteria pollutants such as ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead. The data collected supports air quality index reporting, health advisories, and regulatory enforcement. San Bernardino is situated in the Inland Empire region of Southern California, an area known for challenging air quality due to topography, vehicle emissions, and industrial sources. The station's data helps inform public health decisions and emission reduction strategies. Its location in a densely populated urban area underscores its importance for community exposure assessment and regulatory compliance.

San Bernardino lies in the South Coast Air Basin, a region with persistent air quality challenges due to geographic trapping of pollutants and high emissions from transportation and industry. The monitoring station provides critical data on criteria pollutants, supporting the region's State Implementation Plan for ozone and PM2.5. Its siting in an urban area ensures representative sampling of population exposure, aiding in health risk assessments and regulatory actions under the Clean Air Act.
