The stratosphere is also the altitude limit of jets and weather balloons, as air is roughly a thousand times thinner there than at the troposphere. [ 11 ] Commercial airliners typically cruise at altitudes of 9–12 km (30,000–39,000 ft) which is in the lower reaches of the stratosphere in temperate latitudes. [ 12 ]
Blue light is scattered more than other wavelengths by the gases in the atmosphere, surrounding Earth in a visibly blue layer at the stratosphere, above the clouds of the troposphere, when seen from space on board the ISS at an altitude of 335 km (208 mi) (the Moon is visible as a crescent in the far background).

The stratosphere receives its warmth from the sun and the ozone layer which absorbs ultraviolet radiation. The next layer, the mesosphere, extends from the stratopause to the mesopause (located at an altitude of 85 km (53 mi)). Temperatures in the mesosphere decrease with altitude, and are the coldest in the Earth's atmosphere. [5]
The International Civil Aviation Organization (ICAO) published their "ICAO Standard Atmosphere" as Doc 7488-CD in 1993. It has the same model as the ISA, but extends the altitude coverage to 80 kilometers (262,500 feet). [7] The ICAO Standard Atmosphere, like the ISA, does not contain water vapor. Some of the values defined by ICAO are:
Earth's atmosphere photographed from the International Space Station.The orange and green line of airglow is at roughly the altitude of the Kármán line. [1]The Kármán line (or von Kármán line / v ɒ n ˈ k ɑːr m ɑː n /) [2] is a conventional definition of the edge of space, though it is not universally accepted.
Black carbon in the atmosphere is like dressing Earth in a black shirt on a sunny day. Spaceflight Will Warm Earth’s Stratosphere 4 Degrees, Study Finds Skip to main content
Dunn’s animation of the asteroid shows it skimming Earth at an altitude of 301 miles, ... suggesting that it could even be pulled into Earth’s atmosphere at that altitude.
The stratosphere is also the altitude limit of jet aircraft and weather balloons, as the air density there is roughly 1 ⁄ 1000 of that in the troposphere. [1] Vertical distance comparison The term altitude can have several meanings, and is always qualified by explicitly adding a modifier (e.g. "true altitude"), or implicitly through the ...
