Ozone Chapter 8.
Ozone in the lower atmosphere (i.e. the troposphere and lower stratosphere,..) has a long lifetime, on the order of months to years.
Note that the typical daily variations are 10-20 Dobson Units or about 5%. The largest changes up or down from one day to the next are about 50 DU or 15%.
You keep talking about the lower ozone layer.. We aren't discussing the ozone on the border of the stratosphere and troposphere...we are talking about the ozone which exists up in the high stratosphere...
The air in the high stratosphere is at only 5 mbar. Not much ozone nor anything else compared to the lower stratosphere.
Besides that there is no diurnal variation in the stratosphere. This is from the source I cited.
4.1 Short-Term Variability in the Upper Stratosphere
......
While ozone is produced and destroyed on a time scale of one day or less at altitudes greater than 40 km altitude, this does not in itself lead to a diurnal variation of ozone. This is because when sunlight is present, production and loss are balanced (as given by the steady state approximation in the upper stratosphere). When the sun sets, both production and loss are turned off and the ozone concentration increases slightly as O atoms are converted to ozone molecules in three body reactions involving O, O2, and M.
It looks like your model of daily variation of ozone doesn't hold water. The ozone in the troposphere and lower atmosphere drops at most by 15% at night. And the ozone in the upper stratosphere increases slightly at night.
I guess your source believes that the reactions between O3, nitrogen, hydrogen, natural chlorine and bromine molecules, and yes, even what few CFC's there are all stop at night, or during the arctic winter.
The things you will believe if someone just prints it for you and it seems to agree with what you believe.
I am still waiting for one of you wackos to tell me how you think CFC's at a concentration of 3 parts per BILLION, are a threat to the ozone layer when O3 readily reacts with nitrogen, hydrogen, natural chlorine and bromine molecules which together amount to something over 780,000 parts per MILLION.. The skid mark thought that it was because CFC's are a catalyst, but NO is also a catalyst and exists in the stratosphere at something between 1 and 3 parts per million as opposed to CFC's which are 3 parts per billion...
So lets hear it. How are CFC's a threat to the ozone layer?
