Ozone in California
The Air Resources Board of California (ARB)publishes a large Almanac of
air monitoring data on their website and it is plain they regard tropospheric
ozone as one of their major air quality problems. It is obvious from
the graph below constructed from their data that the measures to reduce vehicle
emissions (and other air pollution) over the last 20 or 30 years have paid
big dividends in better air quality, particularly in Los Angeles.
My point is that with air standards for ozone set at the 0.8 ppm level
it looks clear that for most places, urban or rural, the graph suggests that
this may seldom be achieved and the map below backs this up. Exceedences
are pretty much all over.
Unless you go along with the story that all the ozone exceedences over
the vast area of rural California (see map right from ARB almanac) have
been transported there by wind, there would seem little point in maintaining
these unreasonably high standards set down in the zone of naturally ocurrences.
Talking about transport of ozone bearing air by wind, the map below
also from ARB almanac suggest to me that all possibilities have
been covered, in that air can be transported from anywhere to anywhere by
the wind system indicated by these arrows.
What is the net effect of all this if I am right and the ARB and the EPA
is Canute-like, trying to drive down ozone down below natural levels.
The effect will be, damaging excessive regulations on industry,
power generation and motorists. The cost to the USA taxpayer and the
economy will be in the billions.
