WebbThe thermosphere is a layer of the Earth’s atmosphere that extends from 80 km to 1000 km above the surface. The primary sources of energy input to the thermosphere include solar extreme ultraviolet (EUV) radiation, auroral particle precipitation, and joule heating in high-latitude regions, which strongly influence the thermosphere’s structure and dynamics. The thermosphere contains an appreciable concentration of elemental sodiumlocated in a 10-kilometre (6.2 mi) thick band that occurs at the edge of the mesosphere, 80 to 100 kilometres (50 to 62 mi) above Earth's surface. The sodium has an average concentration of 400,000 atoms per cubic … 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 … Visa mer In contrast to solar XUV radiation, magnetospheric disturbances, indicated on the ground by geomagnetic variations, show an unpredictable impulsive character, from short … Visa mer • Aerial perspective • Aeronomy • Air (classical element) • Air glow 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 no significant vertical wave structure is … 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
