World Ozone Day is also known as International Day for the Preservation of the Ozone Layer and was designated by the United Nations General Assembly in 1994. The observance of this day commemorates the date in 1987 when the Montreal Protocol on Substances that Deplete the Ozone Layer was signed. This day aims to raise awareness about ozone layer depletion and the need to take action by preserving the ozone layer. In the earth’s stratosphere, the ozone layer is a region absorbing most of the Sun’s ultraviolet radiation, thereby protecting the earth from harmful rays. Therefore, the depletion of the ozone layer is a global concern and is the biggest factor in global warming.

History and Significance of World Ozone Day

Charles Fabry and Henri Buisson, both French physicists, discovered the ozone layer in 1913. The scientists deduced that there was no radiation at the ultraviolet end of the spectrum, which was being absorbed by something in the atmosphere. After conducting some tests, the spectrum of the missing radiation was matched to one known chemical, ozone. This is when the properties of ozone were explored and it was found that the ozone in the earth’s stratosphere is a result of ultraviolet light striking ordinary oxygen molecules with two oxygen atoms. This day for the preservation of the ozone layer is therefore observed to create awareness about it and also because it gives us an opportunity to learn about the ways in which we can preserve the planet.
