Temperatures are highly dependent on solar activity, and can rise to 2,000 °C (3,630 °F) or more. Radiation causes the atmospheric particles in this layer to become electrically charged, enabling radio waves to be refracted and thus be received beyond the horizon. Visa mer The thermosphere is the layer in the Earth's atmosphere directly above the mesosphere and below the exosphere. Within this layer of the atmosphere, ultraviolet radiation causes photoionization/photodissociation of molecules, … Visa mer Energy budget The thermospheric temperature can be determined from density observations as well as from direct satellite measurements. The temperature vs. altitude z in Fig. 1 can be simulated by the so-called Visa mer A contraction of the thermosphere has been observed as a possible result in part due to increased carbon dioxide concentrations, the … Visa mer It is convenient to separate the atmospheric regions according to the two temperature minima at an altitude of about 12 kilometres … Visa mer Within the thermosphere above an altitude of about 150 kilometres (93 mi), all atmospheric waves successively become external waves, and … Visa mer In contrast to solar XUV radiation, magnetospheric disturbances, indicated on the ground by geomagnetic variations, show an … Visa mer • Aerial perspective • Aeronomy • Air (classical element) • Air glow Visa mer WebbTemperature of the thermosphere The vertical temperature contrast for the thermosphere of Titan is estimated considering heating by absorption of solar energy, energy loss through infrared radiation by polyatomic molecules, and energy transfer by thermal conduction between the regions of energy deposition and loss.
