Noun
thermosphere (plural thermospheres)
The layer of the Earth's atmosphere directly above the mesosphere and directly below the exosphere.
Phys. 49/7, Springer Verlag, Heidelberg, 1 During low solar activity, about half of the total energy input into the thermosphere is thought to be solar XUV radiation. Source: Internet
Ohmic losses of the Pedersen currents heat the lower thermosphere (see e.g., Magnetospheric electric convection field ). Source: Internet
Orbital characteristics Objects in LEO encounter atmospheric drag from gases in the thermosphere (approximately 80–500 km up) or exosphere (approximately 500 km and up), depending on orbit height. Source: Internet
Since the heat input into the thermosphere occurs at high latitudes (mainly into the auroral regions), the heat transport represented by the term P 2 0 in eq. Source: Internet
Solar XUV radiation The solar X-ray and extreme ultraviolet radiation (XUV) at wavelengths < 170 nm is almost completely absorbed within the thermosphere. Source: Internet
Taking its name from the Greek θερμός (pronounced thermos) meaning heat, the thermosphere begins about convert above the Earth. Source: Internet
