I still await an explanation of how freon, that is heavier than air, manages
to make it to the South pole and finds the magical propert to climb to the
ionisphere and eat ozone.

CO2 is also heavier than air, about 1.5 X air [at standard conditions].

What's missing from the observation are the effects of a turbulent atmosphere
and the specific heat of both freon and CO2 molecules, among others.

In the absence of solar heating and air turbulence both CO2 and FREON would be
hugging the earth's surface and we most likely would not be here [suffocated].

I'm not an atmospheric physicist, but I expect that both CO2 and Freon have
three dimensional motion. They absorb energy from the sun at different rates
[their specific heats and photon absorption cross sections are significantly
different] and expand [become lighter in terms of grams/m^3 @ p=cons.]. Air also
absorbs energy from the sun and expands. The three expansion rates are different
and cause a 'general' lift to the individual gases. This 'lift' is not laminar,
and therefore contributes to a turbulent atmosphere [AKA wind]. As part of the
turbulent flow the heavier molecules are lifted to higher altitudes where they
expand further [become lighter in terms of grams/M^3][Similar to clouds].
Eventually, the lift has insufficient buoyancy to sustain the heavier molecules
and they start a drift back to earth. Some return to earth level. Others are
caught in the updraft and re-cycle to a higher altitude [similar to a vortex
phenomena].

My hypothesis, and qualitative description, would lead to a conclusion that a
band, a thick layer, a region [similar to the E or F regions we are familiar
with] of turbulent heavy gases of varying density forms above the sensible
atmosphere and exhibits turbulent rotation similar to a vortex.

I'm ignorant here and this is just a hypothesis. If we have any atmospheric
physicists or meteorologists on the list I would love to be properly instructed.
