Ozone Layer Recovery

Posted by David Stephen on March 8, 2011 at 3:09 AM

The overall process by which the Ozone Layer protects planet Earth from harmful ultraviolet radiations shows that depleted parts of the ozone hole can be replaced artificially. Part of the process is what this opinion news article seek to explain.


NASA Earth Observatory released images showing Ozone Hole through the years on February 1, 2011. Writings accompanying the images present the 2010 report of science advisers to the Montreal Protocol stating that the protocol has protected the ozone layer from higher level of depletion.


The images show changes in the thickness of the ozone hole over the years in terms of recovery and stability. The Ozone layer can be described as a space containing ozone gas predominant in an upper part of the atmosphere called the stratosphere. The layer helps to prevent harmful ultraviolet rays from reaching the Earth Surface. The ozone layer is crucial to life on planet Earth.


From the knowledge of chemistry, reactive substances are usually in form of solid, liquid or gas which implies that most substances in any of these forms are liable to react with substances alike. Ozone gas can react with several other substances forming products differing in physical and chemical properties from reacting substances; some substances called ozone depleting substances can react with ozone gas and deplete the ozone layer.


Examples of ozone depleting substances are chlorofluorocarbons used for refrigerants and aerosol spray cans, some of these substances escape to the stratosphere where they react with ozone gas forming compounds that cannot prevent harmful ultraviolet rays from reaching the Earth surface.


This is dangerous for man and his environment, which prompted governments to agree to reduce the use of these substances in late 1980's. The agreement is called the Montreal Protocol aimed at phasing out ozone depleting substances.


It has however been predicted that full recovery of the Ozone layer is expected in the middle of the 21st Century. After careful study of the process by which the ozone layer protects planet Earth from harmful ultraviolet rays, I developed an article that suggests possible recovery of the ozone hole artificially. Ultraviolet radiation from the Sun and oxygen gas are involved in reactions leading to creation and destruction of ozone in the stratosphere, this process helps to prevent harmful ultraviolet rays from reaching the earth surface.


Ozone Hole Recovery is an article that suggests using aerodynamic objects to deliver oxygen gas to depleted parts of the ozone layer at lower stratospheric altitude. Expected result will be seen as changes in thickness of the ozone layer. Further scientific and technical review will ensure the process delivers as expected if used in future.

Thank you so much Mr. David. I would kindly wish to ask you a personal chemistry query that has been on my mind for so long. Is there a possibility of bonding three oxygen atoms and if that is possible what are the conditions necessary to create such an atom i.e. the ozone layer atom.
I am a Chemical and Process Engineering student in Moi University in Kenya but i am so much interested in the creation of the artifical ozone layer and the sealig of the ozone hole.
Thanks for reading my message, and i am hoping for a response from you sir.
Thanks in advance.
Yours Faithful

(I can't comment on your article page, so I'm doing it here.) I doubt injecting oxygen could make any difference. There is plenty of oxygen up there. Some other material might help the ozone layer by scavenging those nasty Cl and Br atoms. Maybe sodium hydroxide. Or sodium oxide, or even atomized sodium metal. When Na+ finds Cl or Br, it binds them in NaCl and NaBr. Hydrogen released by reaction of sodium with water might also help, yielding more-stable HCl and HBr.
