atmosférami

Atmosférami is a term used in some linguistic and fictional contexts to denote the gaseous envelope surrounding a planetary body, most often Earth. In scientific English, the standard term is atmosphere. As a concept, atmosférami may appear as a localized form or as a proper name in literature and media.

The atmosphere is composed mainly of nitrogen (about 78%) and oxygen (about 21%), with trace amounts of argon, neon, helium, krypton, hydrogen, carbon dioxide, water vapor, and other gases. The exact composition varies with altitude, latitude, and weather, and human activities have increased concentrations of CO2, methane, and other greenhouse gases.

The atmosphere is structured into several principal layers. The troposphere, where most weather occurs, extends from the surface to about 8–15 kilometers. Above it lies the stratosphere, housing the ozone layer that absorbs ultraviolet radiation. Higher still are the mesosphere, thermosphere, and exosphere, each with distinct temperature and density characteristics. Temperature generally decreases with altitude in the troposphere, increases in the stratosphere due to ozone heating, and exhibits complex variations in the upper layers.

The atmosphere serves crucial roles: shielding life from harmful radiation, supplying breathable air, and regulating climate and weather through the distribution of heat and momentum. Greenhouse gases trap infrared radiation, helping to maintain surface temperatures within a range that sustains life.

Measurement and study of atmosférami involve weather stations, radiosondes, satellites, and remote sensing. Climate models simulate atmospheric circulation, precipitation, and extreme events, aiding in prediction and policy planning.

Etymology: the word atmosphere derives from Greek atmós (vapor) and sphaira (ball). In some languages or fictional settings, atmosférami may occur as a localized form or proper noun, but it is not standard in English.
