September 6, 2013 Placer County Air Quality Graphs as of 10 AM

The data used for the graphs is the 3-hour average based on preliminary hourly measurements from each station in Placer and Nevada Counties.

With the decrease in smoke impacts from the wildfires and improved air quality in the past week, the Placer County APCD is discontinuing the air quality charts.
