    The thermosphere is the layer in the Earth's atmosphere directly ... etc.). The thermosphere becomes a damped oscillator system with low-pass filter characteristics ...

  3. Atmospheric temperature - Wikipedia

    en.wikipedia.org/wiki/Atmospheric_temperature

    These layers are the troposphere, stratosphere, mesosphere, and thermosphere. The troposphere is the lowest of the four layers and extends from the surface of the Earth to about 11 km (6.8 mi) into the atmosphere, where the tropopause (the boundary between the troposphere stratosphere) is located. The width of the troposphere can vary depending ...

  4. Atmosphere of Earth - Wikipedia

    en.wikipedia.org/wiki/Atmosphere_of_Earth

    The thermosphere is the second-highest layer of Earth's atmosphere. It extends from the mesopause (which separates it from the mesosphere) at an altitude of about 80 km (50 mi; 260,000 ft) up to the thermopause at an altitude range of 500–1000 km (310–620 mi; 1,600,000–3,300,000 ft).

  5. Ionosphere - Wikipedia

    en.wikipedia.org/wiki/Ionosphere

    Ionosphere. The ionosphere (/ aɪˈɒnəˌsfɪər /) [1][2] is the ionized part of the upper atmosphere of Earth, from about 48 km (30 mi) to 965 km (600 mi) above sea level, [3] a region that includes the thermosphere and parts of the mesosphere and exosphere. The ionosphere is ionized by solar radiation.

  6. Atmosphere - Wikipedia

    en.wikipedia.org/wiki/Atmosphere

    An atmosphere (from Ancient Greek ἀτμός (atmós) 'vapour, steam' and σφαῖρα (sphaîra) 'sphere') [1] is a layer of gases that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. A stellar atmosphere is the ...

  7. Stratosphere - Wikipedia

    en.wikipedia.org/wiki/Stratosphere

    The stratosphere image is dominated by blues and greens, which indicates a cooling over time. [1] Diagram showing the five primary layers of the Earth's atmosphere: exosphere, thermosphere, mesosphere, stratosphere, and troposphere. The layers are not to scale. The stratosphere (/ ˈstrætəˌsfɪər, - toʊ -/) is the second-lowest layer of ...

  8. Mesosphere - Wikipedia

    en.wikipedia.org/wiki/Mesosphere

    The mesosphere (/ ˈmɛsəsfɪər, ˈmɛz -, ˈmiːsə -, - zə -/; [1] from Ancient Greek μέσος (mésos) 'middle' and - sphere) is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, temperature decreases as altitude increases. This characteristic is used to define ...

  9. Thermopause - Wikipedia

    en.wikipedia.org/wiki/Thermopause

    The thermopause is the atmospheric boundary of Earth's energy system, located at the top of the thermosphere. [1] The temperature of the thermopause could range from nearly absolute zero to 987.547 °C (1,810 °F). Below this, the atmosphere is defined to be active [clarification needed] on the insolation received, due to the increased presence ...
