It is part of the state-level air quality monitoring network managed by the California Air Resources Board (CARB), which feeds data into the US EPA Air Quality System (AQS). As a fixed-site monitor, it provides continuous ambient air quality measurements essential for assessing compliance with National Ambient Air Quality Standards (NAAQS). The station operates under California's stringent air quality regulations, which include monitoring for criteria pollutants such as ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead. The last reported sample date is July 12, 2025, indicating active data collection. While specific parameters measured are not detailed, typical urban stations in the San Francisco Bay Area monitor a standard suite of pollutants to address regional smog and particulate concerns. San Jose - Jackson serves a densely populated urban area in Silicon Valley, where air quality is influenced by traffic emissions, industrial activity, and seasonal wildfires. The data collected supports local air district planning, health advisories, and long-term trend analysis. This station plays a key role in the Bay Area Air Quality Management District's network, helping to protect public health and meet federal and state air quality goals.
