Weed Air Monitoring Station | California Air Quality Monitoring

Weed Air Monitoring Station is an operational air quality monitoring facility located at 575 White Avenue in Weed, California, within Siskiyou County. It is operated by the California Air Resources Board and contributes to the US EPA Air Quality System (AQS) network, which tracks criteria pollutants and other atmospheric parameters across the United States. The station operates under the regulatory framework of the US Clean Air Act and EPA ambient air quality standards. While specific parameters measured are not detailed, typical air monitoring stations in California measure ozone, particulate matter (PM2.5 and PM10), nitrogen dioxide, sulfur dioxide, carbon monoxide, and lead, along with meteorological data. The California Air Resources Board ensures siting representativeness and data quality through rigorous protocols. This station serves the community of Weed and surrounding areas by providing critical data for air quality assessments, public health advisories, and regulatory compliance. Its location in a rural area of Siskiyou County helps characterize regional air quality, which is influenced by agricultural activities, wildfires, and transportation emissions.

Weed is located in the Shasta Valley of northern California, an area with a mix of agricultural land, forests, and rural communities. Air quality in the region can be affected by seasonal wildfires, agricultural burning, and vehicle emissions. The monitoring station helps track pollutants such as particulate matter and ozone, which are of concern for public health and environmental compliance. Its data supports the California Air Resources Board's efforts to meet state and federal air quality standards.
