Stratosphere
The stratosphere is the Earth's second major atmospheric layer, located above the troposphere and below the mesosphere, with altitudes ranging from approximately 8 to 18 km depending on latitude. Temperature increases with altitude in this layer, reaching around -3°C at its top, and it hosts unique life forms, including certain bacteria and birds. Notably, the stratosphere was explored through experiments that revealed its characteristics, including the discovery of an isothermal layer by Léon Teisserenc de Bort and Richard Assmann.

- 5. So what isStratosphere?? The stratosphere is the second major layer of Earth’s atmosphere just above the troposphere and below the mesosphere .It is stratified in temperature, with warmer layers higher up and cooler layers farther down. At moderate latitudes the stratosphere is situated between about 10–13 km and 50 km altitude above the surface, while at the poles it starts at about 8 km altitude, and near the equator it may start at altitudes as high as 18 km.
- 6. Let’s know moreinformation on the Stratosphere!! Within this layer, temperature increases as altitude increases. The top of the stratosphere has a temperature of about −3°C just slightly below the freezing point of water. Methane ,while not a direct cause of ozone destruction in the stratosphere, does lead to the formation of compounds that destroy ozone.

In 2001 an Indian experiment, involving a high-altitude balloon, was carried out at a height of 41 kilometres and a sample of dust was collected with bacterial material inside.Also, some bird species have been reported to fly at the lower levels of the stratosphere. On November 29, 1973, a Rüppell's vulture was ingested into a jet engine 11,552 m above the Ivory Coast, and bar-headed geese reportedly overfly Mount Everest's summit, which is 8,848 m.
- 10. DISCOVERY OF STRATOSPHERE… €Léon Teisserenc de Bort and Richard Assmann, in separate publications and following years of observations, announced the discovery of an isothermal layer at around 11–14 km, which is the base of the lower stratosphere. This was based on temperature profiles from unmanned instrumented balloons.
