The phrase "atmosphere equilibrium" is correct and usable in written English.
It can be used in contexts related to environmental science, meteorology, or physics when discussing the balance of atmospheric conditions.
Example: "The researchers studied the factors that contribute to atmosphere equilibrium in order to understand climate change better."
Alternatives: "atmospheric balance" or "air equilibrium".
4He concentrations in the shallow aquifer above the Great Artesian Basin range from atmospheric equilibrium to 1000 times enriched over atmosphere.
The temperature range given for a doubling of CO2 in the atmosphere, called equilibrium climate sensitivity, was 2.0C to 4.5C in that report.
The carbon dioxide in the atmosphere is in equilibrium with, and far less abundant than, the oceanic inventory of carbon dioxide, bicarbonate ions (HCO3-), and carbonate ions (CO32-).
This eventually led to the concussion theory of rain-making -- the idea that by setting off explosions (artillery fire would do nicely) the atmosphere's tenuous equilibrium would be disturbed and rain would fall.
This result demonstrates that an atmosphere near thermal equilibrium was achieved in the HWD apparatus used.
The use of hot-wall deposition (HWD), which can provide an atmosphere near thermal equilibrium, is therefore indicated here [18].
The solubility limit of Pb in ZnSe is quite narrow, less than 1 mol% in the film form, indicating that an atmosphere near thermal equilibrium is achieved in the apparatus used.
In Antarctic winter, there is no real tropopause to prevent such descent, hence the quotes in the title: the temperature profile is often that of a radiative equilibrium atmosphere.
The basic thermal structure is set by the balance between absorption of solar UV and infrared radiation to space, but it is significantly modified by momentum deposition by atmospheric waves, notably internal atmospheric gravity (buoyancy) waves, that drives the atmosphere away from radiative equilibrium.
When the muscles of inspiration relax, the volume of chest and lungs decreases, lung air becomes transiently compressed, its pressure rises above atmospheric pressure, and flow into the atmosphere results until pressure equilibrium is reached at the original lung volume.
