Correction: Mary Nichols said that Nevada County has the worst ozone than any rural county in the nation. I had omitted the rural county reference in my notes, thus created a misleading post. Several people have requested a correction. I have removed the LA chart, as it is not applicable to the post. I am working on a much longer post on the ozone issue, specifically the role of higher temperature in the generation of ozone. Stay tuned.

Eyeballing the chart, It looks like LA is just a bit higher than Nevada County. These are measurements, they are not the product of a model that creates the red blobs on the ozone chart.

Update #1: (09-30-10,1400) Here is a plot of the Nevada County Ozone for the summer of 2010. We did not exceed the EPA standard of 75ppb (.075ppm) Came close twice, but did not exceed the limit. (Click for a larger impage.)
