Atmosphere (Air Quality)

The layer of life-supporting gases (air) that surrounds the earth

Atmosphere (Atmospheric Chemistry)

The sum total of all the gases surrounding the Earth, extending several hundred kilometers above the surface in a mechanical mixture of various gases in fluid-like motion. The permanent constituents are molecular nitrogen; 78.1%, molecular oxygen; 20.9%, argon; 0.934%, and approximately 0.036% carbon dioxide. Various other components exist in trace amounts. Not to be under emphasized, these trace components are where the interesting atmospheric chemistry occurs. The atmosphere can also be artificially divided into layers. Example: the troposphere (the layer closest to the earth) and the stratosphere (the layer above the troposphere).

Trenberth; pp. 53-115; 1992; Cambridge University Press; London.]

Atmosphere (Carpet)

A standard unit of pressure exerted by a 29.92 inch column of mercury at sea level and equal to 1000 grams per square centimeter.

Atmosphere (Champagne)

Unit of measure for pressure inside a bottle of sparking wine or champagne. 1 Atmosphere equals 14.7 pounds per square inch (the standard atmospheric pressure at sea level in the world). Commercial sparkling wines commonly contain 4 to 6 atmospheres of CO2 pressure when measured at room temperature. A well-chilled sparkling wine contains the same amount of CO2, but because more of the CO2 remains dissolved in the wine at colder temperatures, the measured pressure is lower. And, the bubbles last longer in the glass.

Atmosphere (Cinematography)

Extras who are staged and photographed to portray normal human traffic needed to add detail in various script situations. (Production)

Atmosphere (Climatology)

The mixture of gases, such as oxygen and nitrogen, which make up the air around our planet.

Atmosphere (Entertainment Industry)

Another term for "extras" or "background artists".

Atmosphere (Environment)

The 500 km thick layer of air surrounding the earth which supports the existence of all flora and fauna.

Atmosphere (Explosives)

The envelope of air surrounding the earth; also, the body of gases surrounding or comprising any planet or other celestial body. Atmospheric pressure may be measured as weight per area. On earth, normal air pressure at sea level is 14.7 pounds of weight per square inch, or 1033 grams of weight per square centimeter. Expressed in more formal units of force per area, one atmosphere is equal to 1,013,300 dynes/cm2. One million dynes per square centimeter has been set equal to one bar, therefore one atmosphere is equal to 1.0133 bars.

Atmosphere (Film Production)

Extras who are staged and photographed to portray normal human traffic needed to add detail in various script situations. (Production)

Atmosphere (Forestry)

The gaseous envelope (air) surrounding the earth

Atmosphere (Geography)

The envelope of gases surrounding the earth

Atmosphere (Import Cars)

The mass of air that surrounds Earth.

Atmosphere (Natural Gas)

The outdoor air in general. Also a mixture of gases within any specified chamber, such as heat-treating furnace.

Atmosphere (Oceanography)

The Earth's atmosphere is the layer of gases that surround the Earth. It is a mixture of nitrogen (78%) and oxygen (21%). The atmospheric gases in the remaining 1 percent are argon (0.9%), carbon dioxide (0.03%), varying amounts of water vapor, and trace amounts of hydrogen, ozone, methane, carbon monoxide, helium, neon, krypton, and xenon.

Atmosphere (Physical Geography)

The atmosphere is the vast gaseous envelope of air that surrounds the Earth. Its boundaries are not easily defined. The atmosphere contains a complex system of gases and suspended particles that behave in many ways like fluids. Many of its constituents are derived from the Earth by way of chemical and biochemical reactions.

Atmosphere (Planetary Science)

Mixture of gases that surround and are gravitationally attached to a planet.

Atmosphere (Sanitation)

(1) The outer part of the earth surrounding the lithosphere and hydrosphere and consisting predominantly of air. It contains other matter, such as water vapor and dust particles. (2) The pressure of air at mean sea level on the earth's surface.

Atmosphere (Satellite Meteorology)

The envelope of air surrounding the planet Earth and held in place due to the Earth’s gravitational attraction. The Earth’s atmosphere is subdivided vertically into the troposphere, stratosphere, mesosphere, and thermosphere.

Atmosphere (Science)

A mixture of gases surrounding the Earth, primarily composed of nitrogen and oxygen

Atmosphere (Weather)

The gaseous or air portion of the physical environment that encircles a planet. In the case of the earth, it is held more or less near the surface by the earth's gravitational attraction. The divisions of the atmosphere include the troposphere, the stratosphere, the mesosphere, the ionosphere, and the exosphere.
