I’m still thinking about ozone and the summer of 2013. I think the good news in California is also the bad news.
The bad? South Coast’s lowest-ever number of eight-hour ozone exceedances is still the worst in the country this year. The Valley’s lowest-ever is second worst. And third place is not even close to South Coast or the Valley.
I checked the number of exceedances for the one-hour ozone standard, too. The Valley has not breached the standard this year, which would be a first if it holds up through the end of the warm season.
South Coast, which includes Los Angeles, Riverside, San Bernardino and Orange counties, had four exceedances of the one-hour standard. Houston had one. I found no others.
