* The Sacramento region is designated as a severe nonattainment area for the 1997 federal 8-hour ozone standard with an attainment deadline of June 2019. This federal nonattainment area includes all of Sacramento and Yolo counties and portions of El Dorado, Placer, Sutter and Solano counties. It does not include Nevada County (Grass Valley), which has its own nonattainment area for outreach, planning and regulatory purposes. Nor does it include Yuba City, which is outside of this federal boundary.

The real-time Particulate Matter (PM2.5) data displayed on this page is for public information reporting and forecasting only. Per state and federal regulations, it is not used for attainment determination purposes.
Fine Particulate Matter, known as PM2.5, is a complex mixture that may contain soot, smoke, metals, nitrates, sulfates, dust, water and tire rubber. It can be directly emitted, as in smoke from a fire, or it can form in the atmosphere from reactions of gases such as nitrogen oxides.
