While searching for debris from nuclear bomb tests, Christian Junge discovered in 1960 a layer of microscopic aerosol particles between the tropopause and about 18 miles (30 km) altitude. These particles are composed of sulfuric acid and water and are formed by the chemical transformation of sulfur-containing gases. This layer is called the Junge Layer or the Stratospheric Aerosol Layer. 6, record 1, English, - stratospheric%20aerosol%20layer

The relative maximum of the global vertical aerosol concentration profile in the lower stratosphere is commonly referred to as the Junge aerosol layer, or simply the Junge layer. It is of great importance to study the formation of this layer and to monitor its changes because of the possible impacts of these stratospheric aerosols to global climate. At present, the formation mechanism of the Junge layer is not well understood. Current theories of Junge layer formation include the injection of sulfate particles by volcanic eruptions, turbulent diffusion of tropospheric sulfates, natural (biogenic) emissions of carbonyl sulfide, and other processes. 7, record 1, English, - stratospheric%20aerosol%20layer

Les sulfates disparaissent brusquement de la couche d'aérosols stratosphériques au-delà de 22-23 km d'altitude [...] Il semble donc qu'ils apparaîtraient à ce niveau par réaction [de l'acide sulfurique] néoformé sur l'ammoniac et qu'ils se sédimentent lentement vers le sol. Cette couche joue donc un rôle important dans le cycle biogéochimique du soufre et dans une moindre mesure dans celui de l'azote. 1, record 1, French, - couche%20d%27a%C3%A9rosols%20stratosph%C3%A9riques
