Thermopause height
The thermopause is the atmospheric boundary of Earth's energy system, located at the top of the thermosphere. 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 on the insolation received, due to the increased presence of heavier gases such as monatomic oxygen. The solar constant is thus expressed at th… WebbThe thermopause is the atmospheric boundary of Earth's energy system, located at the top of the thermosphere.

Webb22 apr. 2024 · Definition The region of an atmosphere called the thermosphere is characterized by an increase in neutral temperature as a function of altitude and asymptotes to a relatively constant temperature. The corresponding neutral atmospheric density is decreasing with altitude. In general, air pressure and density decrease with altitude in the atmosphere. However, the temperature has a more complicated profile with altitude, and may remain relatively constant or even increase with altitude in some regions (see the temperature section, below). Because the general pattern of the temperature/altitude profile, or lapse rate, is constant and measurable by mean…
