Thermosphere role
WebbPlanetary upper atmospheres-coexisting thermospheres and ionospheres-form an important boundary between the planet itself and interplanetary space. The solar wind and radiation from the Sun may react with the upper atmosphere directly, as in the case of Venus.

WebbLa thermosphère est la région où près des pôles se forment les aurores boréales et australes. Aurores boréales. La partie inférieure de la thermosphère est appelée l'ionosphère. L'ionosphère réfléchit les ondes courtes (ondes radio). Ces ondes, émises par un émetteur, rebondissent sur l'ionosphère et sont renvoyées vers la Terre.

WebbDefinition The highest layer of the Atmosphere above the Mesosphere extending from approximately 90km above the surface to 10,000km where it gradually merges into Space. Description The Thermosphere is characterised by rising temperature with height - temperatures rising to 1000°C.
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, creating ions; the thermosphere thus constitutes the larger part of the ionosphere. … Visa mer It is convenient to separate the atmospheric regions according to the two temperature minima at an altitude of about 12 kilometres (7.5 mi) (the tropopause) and at about 85 kilometres (53 mi) (the Visa mer Within the thermosphere above an altitude of about 150 kilometres (93 mi), all atmospheric waves successively become external waves, and … Visa mer A contraction of the thermosphere has been observed as a possible result in part due to increased carbon dioxide concentrations, the strongest cooling and contraction … Visa mer Energy budget The thermospheric temperature can be determined from density observations as well as from direct satellite measurements.
