The stratosphere is the atmospheric layer situated above the troposphere, where most weather phenomena occur. It extends from approximately 10 to 50 kilometers above the Earth’s surface. This region is characterized by a stable temperature gradient, increasing with altitude due to the absorption of ultraviolet radiation by the ozone layer. A notable example of its unique conditions is the stable flight environment it provides, often exploited by commercial aircraft.
This atmospheric layer plays a critical role in protecting life on Earth by absorbing harmful ultraviolet (UV) radiation from the sun. The ozone layer, residing within this layer, is essential for this protective function. Its discovery in the early 20th century and subsequent research highlighted the impact of human activities on its delicate balance. Understanding its composition and dynamics is crucial for mitigating potential threats to this vital shield. Furthermore, its stable temperature gradient and low turbulence make it ideal for long-distance air travel.
