The ozone layer in the Earth’s atmosphere absorbs Sun’s Ultraviolet radiations. It is mainly found in the lower portion of the stratosphere from approximately 20 to 30 kilometers above the Earth. The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson. Its properties were explored in detail by the British meteorologist GMB Dobson.

World Ozone Day 2013 is being observed to invite the attention of global fraternity towards the fast depleting ozone layer. It was decided by the United Nations Environment Program in 1994 to sensitize the world community on significance of this issue. Since then, it is being observed every year on September 16 and various awareness activities are organized by government, NGOs as well as organizations to highlight the importance of this day. This year’s theme of World Ozone Day 2013 is “A Healthy Atmosphere, the Future We Want”.
