The Yolo-Solano AQMD monitors ambient air quality to protect public health and comply with federal and state requirements. Our monitoring network provides real-time data that allows the District to forecast air quality and issues advisories to the public as needed. The monitoring network also allows the District to show progress toward air quality standards.

Annual Network Plan
ARB produces an Annual Network Plan that details the state’s air monitoring network.

The state Annual Network Plan is submitted to the U.S. Environmental Protection Agency for review.
