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 mesopause) (Figure 1). The thermosphere (or the upper atmosphere) is the height region above 85 … Meer weergeven 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 … Meer weergeven Within the thermosphere above an altitude of about 150 kilometres (93 mi), all atmospheric waves successively become external … Meer weergeven A contraction of the thermosphere has been observed as a possible result in part due to increased carbon dioxide concentrations, … Meer weergeven Energy budget The thermospheric temperature can be determined from density observations as well as from … Meer weergeven In contrast to solar XUV radiation, magnetospheric disturbances, indicated on the ground by geomagnetic variations, show an unpredictable impulsive character, … Meer weergeven • Aerial perspective • Aeronomy • Air (classical element) Meer weergeven WebThe thermosphere is the fourth and outermost layer of the Earth’s atmosphere. It is located above the mesosphere and below the exosphere, and it is characterized by a steady increase in temperature with altitude. The thermosphere is divided into two sub-layers, the lower thermosphere (80-550 km) and the upper thermosphere (550-640 km).
