Regner provided support of the Ozone hole theory below. My rsponse
Subject political:
Regner, I am sure that if you take into account the quantities of O2 relative
to O3 , even if the figures you provide with higher absorbtion of UV for O3
than O2 were correct , that the major absorbtion factor is the oxygen, simply
because there is so much more of it.
However I think the figures and the theories presernted are fudged for
political reasons, and I could furnish a contrary opinion... if you want , but
it is of no import really, the times they are a changing. You said,
The depletion of the O3 layer
seems to have slowed down, lately, and that is attributed to the international
ban on CFCs.
Like as in also this last year the worlds temperature has dropped considerably
due to climate change, a preferred buzz word over Global Warming, faced as we
are with the threat by some of another mini ice age. . Snow where it never
snowed before, North, and snow here in the South .. where it is rare..
Can you confirm the sun has been rather quiet? NASA had to explain it as the
"cycles always vary"..
I meant to ask you before, Seeing as you are in the right position, can you get
access to a trustworthy record of the suns UV spectrum variation since at least
the 1950"s and from when satellite records were begun.

But I noticed this little bit which separates the real science from the
pseudo..
"A 2005 study showed that a gamma-ray burst originating within 6,500
light-years of Earth could be enough to strip away the ozone layer and cause a
mass extinction. ""
The Ozone layer plays little part in filtering our suns UV rays..
Ozone, O3, has an absorption peak at 254nm of 1e-17/[1/cm^2] with a width of
40nm
(see, e.g., Parisse, Brion & Malicet, 1996, Chem. Phys. Letters, 248, 31-36).
It is actually quite close to the Gaussian: 1.14*exp(-((lambda-254.)/24.)^2).
This is a photo-detachment continuum, meaning that the molecule dissociates
into an
O2 molecule and a free oxygen atom. These can combine with others to form O3
again.
O2, on the other hand, has a 3e-17/[1/cm^2] peak around 60nm and a
1.5e-17/[1/cm^2]
peak around 140nm - same magnitude as for O3 but at much short wavelength in
the
vacuum UV (VUV). There are hardly any Solar photons there.
There is also a 7e-24/[1/cm^2] peak at 200nm - this is a photo-detachment
continuum
causing dissociation into two free oxygen atoms when absorbing this light.
These free atoms join with O2 molecules to form new O3 molecules (as opposed
to the
recycling described above). Due to the very low cross-section and the fewer
Solar photons
available at such short wavelengths, this is a fairly slow process.
Note that this O2 absorption is almost 7 orders of magnitude weaker than
the
absorption by O3. Most of O2's UV absorption happens in the UV-C band and
beyond,
where there are hardly any Solar photons. Most of the harmful UV photons from
the Sun
fall in the UV-B band which is completely covered by the O3 absorption. The
less harm-
ful UV-A band is only partially covered by O3.
See, e.g., Solar Radiation Spectrum from Wikipedia
Source of absorption spectra:
MPI-Mainz-UV-VIS Spectral Atlas of Gaseous Molecules
Ozone is easily destroyed by the radicals NO, OH, Cl and Br which acts as
catalysts
(are not consumed in the process) and each radical can destroy more than
100,000 O3
molecules. The action of these free radicals and the formation of new O3 in
the
presence of sunlight, obviously results in a yearly cyclic variation in O3
concentrations
in the Polar regions - that is a well known and natural cycle.
What has changed, however, is the concentrations of Cl and Br due to human
activity.
These increases have caused a decline in the minimum (winter) concentrations
of O3 in
the Polar regions. These are the much cited ozone-holes. The depletion of the
O3 layer
seems to have slowed down, lately, and that is attributed to the
international ban on CFCs.

The ozone layer is created by the action of Oxygen filtering out UV. The
reaction is analogous to surf when the wave hits the beach. (a lot of froth)
The ozone layer dissappears (and always has) at both poles during the long
winter night, and comes back quickly as soon as the sun sees some O2.
You do not see much media on ozone holes today HA! Gone the way of nuclear
winter, and followed by global warming, which is now replaced with the climate
change buzz word, preparing for a possible new ice age.. all our fault still ..
They make me sick...
