The station collects air quality data, with the most recent sample recorded on June 30, 2025. While specific parameters measured are not detailed, typical air monitoring stations in California track criteria pollutants such as ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead, in compliance with the Clean Air Act and National Ambient Air Quality Standards (NAAQS).
