The composition of the Earth's atmosphere is different from the other planets because the various life processes that have transpired on the planet have introduced free molecular oxygen. [7] Much of Mercury's atmosphere has been blasted away by the solar wind. [8] The only moon that has retained a dense atmosphere is Titan.
In 1911 Kilner published one of the first western medical studies of the "Human Atmosphere" or Aura, proposing its existence, nature and possible use in medical diagnosis and prognosis. In its conviction that the human energy field is an indicator of health and mood, Kilner's study resembles the later work of Harold Saxton Burr .
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).
Atmospheric chemistry is a branch of atmospheric science that studies the chemistry of the Earth's atmosphere and that of other planets. This multidisciplinary approach of research draws on environmental chemistry, physics, meteorology, computer modeling, oceanography, geology and volcanology, climatology and other disciplines to understand both natural and human-induced changes in atmospheric ...
An atmosphere (from Ancient Greek ἀτμός (atmós) 'vapour, steam' and σφαῖρα (sphaîra) 'sphere') [1] is a layer of gases that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low.
The troposphere is the lowest of the four layers and extends from the surface of the Earth to about 11 km (6.8 mi) into the atmosphere, where the tropopause (the boundary between the troposphere stratosphere) is located. The width of the troposphere can vary depending on latitude: for example, the troposphere is thicker in the tropics (about 16 ...
UAH provide data on three broad levels of the atmosphere. The Lower troposphere - TLT (originally called T2LT). The mid troposphere - TMT; The lower stratosphere - TLS [3] Data are provided as temperature anomalies against the seasonal average over a past basis period, as well as in absolute temperature values. The baseline period for the ...
In particular, CO 2 stays in the atmosphere for at least 150 years and up to 1000 years, [73] whilst methane disappears within a decade or so, [74] and nitrous oxides last about 100 years. [75] The graph gives some indication of which regions have contributed most to human-induced climate change.
