Operated under the California Air Resources Board (CARB), this station is part of the broader US EPA Air Quality System (AQS) network, which monitors criteria pollutants and other atmospheric parameters to ensure compliance with National Ambient Air Quality Standards (NAAQS). The station's last reported sample date is July 31, 2025, indicating ongoing data collection. As part of California's extensive air monitoring network, this station likely measures pollutants such as ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead, though specific parameters are not detailed. The station's siting in a rural area of the Sacramento Valley provides representative data for regional air quality, complementing urban monitors in nearby cities like Chico and Sacramento. CARB's network adheres to EPA monitoring regulations and quality assurance protocols. The environmental significance of this station lies in its contribution to understanding air quality trends in California's agricultural Central Valley, where sources include farming activities, wildfires, and transportation. Data from this station supports public health advisories, regulatory compliance, and research on air pollution impacts. Its long-term operation helps track progress toward cleaner air standards and informs local air quality management strategies.
Environmental context
Willows-Colusa Street station operates in California's Sacramento Valley, a region with significant agricultural activity and occasional wildfire smoke. The station's rural siting provides baseline air quality data away from major urban sources, helping to distinguish regional background pollution from local emissions. Monitoring here supports the California Air Resources Board's efforts to meet federal and state air quality standards, particularly for ozone and particulate matter, which are concerns in the Central Valley due to topography and meteorological conditions.
