Thermosphere in a sentence

The Thermosphere Climate Index calculates how much heat energy carbon dioxide and nitric oxide molecules in the thermosphere are radiating into space (and to the lower atmosphere).

The cooling thermosphere does not affect the troposphere, the layer of the atmosphere closest to Earth’s surface where people live.

This boundary is somewhat arbitrary, but it’s located between the mesosphere and the thermosphere—a kind of end-of-the-line for the atmosphere.

In addition to molecular hydrogen, the thermosphere-corona contains many free hydrogen atoms.

Ohmic losses of the Pedersen currents heat the lower thermosphere (see e.g., Magnetospheric electric convection field ).

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.

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.

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.

Taking its name from the Greek θερμός (pronounced thermos) meaning heat, the thermosphere begins about convert above the Earth.

The mass of the thermosphere above about 85 km is only 0.002% of the total mass.

Therefore, no significant energetic feedback from the thermosphere to the lower atmospheric regions can be expected.

The stratosphere, mesosphere and lowest part of the thermosphere are collectively referred to as the "middle atmosphere", which spans heights from approximately convert to convert.

The sum of these modes determines the "travel time" of the disturbance to the lower latitudes, and thus the response time of the thermosphere with respect to the magnetospheric disturbance.

The tenuous thermosphere extends over two planetary radii from the nominal surface, which is defined to lie at a pressure of 1 bar.

The thermosphere becomes a damped oscillator system with low-pass filter characteristics.

The Uranian thermosphere, together with the upper part of the stratosphere, corresponds to the ionosphere of Uranus.

The vehicle started encountering more significant air density in the lower thermosphere at about convert, at around Mach 25, convert.

Within the thermosphere above about 150 km height, all atmospheric waves successively become external waves, and no significant vertical wave structure is visible.
