The temperature of the thermopause could range from nearly absolute zero to 987.547 °C (1,810 °F). Below this, the atmosphere is defined to be active [clarification needed] on the insolation received, due to the increased presence of heavier gases such as monatomic oxygen. The solar constant is thus expressed at
The lower boundary of the exosphere is called the thermopause or exobase. It 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 ]
The border between the thermosphere and exosphere is known as the thermopause. The highly attenuated gas in this layer can reach 2,500 °C (4,530 °F). Despite the high temperature, an observer or object will experience low temperatures in the thermosphere, because the extremely low density of the gas (practically a hard vacuum ) is ...
The exosphere is the outermost layer of Earth's atmosphere (though it is so tenuous that some scientists consider it to be part of interplanetary space rather than part of the atmosphere). It extends from the thermopause (also known as the "exobase") at the top of the thermosphere to a poorly defined boundary with the solar wind and ...
Exosphere – The outermost layer of an atmosphere; Exobase – The lower boundary of the exosphere; Thermopause – The upper boundary of the thermosphere; Thermosphere – The layer of the atmosphere above the mesosphere and below the exosphere; Mesopause – The temperature minimum at the boundary between the mesosphere and the thermosphere
The localized greenhouse effect is stronger in locations where the lapse rate is stronger. In Antarctica, thermal inversions in the atmosphere (so that air at higher altitudes is warmer) sometimes cause the localized greenhouse effect to become negative (signifying enhanced radiative cooling to space instead of inhibited radiative cooling as is ...
Space weather effects. Space weather is a branch of space physics and aeronomy, or heliophysics, concerned with the varying conditions within the Solar System and its heliosphere. This includes the effects of the solar wind, especially on the Earth's magnetosphere, ionosphere, thermosphere, and exosphere. [1]
First rocket to pass the thermopause and enter the exosphere. At 682 miles (1,098 km) altitude and 3,335 miles range, the 3-stage Jupiter-C breaks both records and achieves MACH 18 velocity.
