WebThe atmospheric density decreases as the altitude increases. This variation can be approximately modeled using the barometric formula. More sophisticated models are used by meteorologists and space agencies to predict weather and orbital decay of satellites. The average mass of the atmosphere is about 5,000 trillion metric tons. WebMar 12, 2024 · Air density varies with atmospheric pressure and air temperature. In general, higher altitudes correspond to lower atmospheric pressure and lower air density. Hotter temperatures correlate to a lower air density also. The density of the air also depends on humidity and other factors; moist air and dry air carry different densities.

WebIt is also called the critical altitude, as this is the altitude where barometric conditions no longer apply. Atmospheric temperature becomes nearly a constant above this altitude. [5] On Earth, the altitude of the exobase ranges from about 500 to 1,000 kilometres (310 to 620 mi) depending on solar activity. [6] WebAlthough the thermosphere is considered part of Earth's atmosphere, the air density is so low in this layer that most of the thermosphere is what we normally think of as outer space. In fact, the most common definition says that space begins at an altitude of 100 km (62 miles), slightly above the mesopause at the bottom of the thermosphere.
