Ozone in the stratosphere protects life on Earth from harmful ultraviolet (UV) radiation and is therefore often called 'good' ozone. Ozone was identified in the atmosphere by Schnbein in 1867 and soon corroborated by Andrews in 1868 (Rubin, 2001) using chemical means.The discovery of ozone in the Earth's atmosphere marked a significant milestone in our understanding of atmospheric chemistry and its crucial role in safeguarding life on our planet. The term "ozone" itself is derived from the Greek word "ozein," meaning "to smell," as the gas has a distinct, sharp odor.
As researchers delved deeper into atmospheric science, the identification of ozone in the stratosphere gained prominence due to its critical function in shielding life on Earth from harmful ultraviolet (UV) radiation. This specific region of the atmosphere, often referred to as the ozone layer, absorbs and attenuates the majority of the sun's ultraviolet rays before they reach the Earth's surface. This protective layer is colloquially known as "good" ozone.
The groundbreaking discovery of ozone in the stratosphere can be attributed to Christian Friedrich Schnbein, a German-Swiss chemist, who first identified the gas in 1867. His findings were swiftly corroborated by Thomas Andrews in 1868, providing a more robust foundation for our understanding of ozone's presence in the atmosphere.
The methodology employed by Schnbein and Andrews involved chemical means, highlighting the pioneering techniques available during the late 19th century. Their experiments allowed for the identification and quantification of ozone, laying the groundwork for subsequent research into its distribution and significance in the Earth's atmosphere.
Over the years, as scientific tools and methods advanced, our understanding of ozone dynamics expanded. Unfortunately, the advent of human-made chemicals, particularly chlorofluorocarbons (CFCs), led to the depletion of ozone in the stratosphere, primarily over Antarctica. This phenomenon, known as the ozone hole, raised global awareness about the environmental impact of human activities and prompted international efforts to mitigate ozone-depleting substances.
In 1987, the Montreal Protocol was established, marking a landmark global agreement to phase out the production and consumption of ozone-depleting substances. The success of this treaty underscores the importance of international cooperation in addressing environmental challenges.
The ongoing study of ozone continues to be a crucial component of atmospheric science. Scientists monitor its levels, study its fluctuations, and assess the effectiveness of environmental policies aimed at preserving and restoring the ozone layer. The story of ozone discovery not only highlights the remarkable progress in atmospheric chemistry but also emphasizes the need for responsible stewardship of our planet's delicate environmental balance.
