13 Μαΐ 2019 · The ionosphere and thermosphere (IT) is coupled in an intricate way to the magnetosphere via electromagnetic fields, energetic charged particles, currents and neutral gas, and across many spatial and temporal scales. Thus, to fully understand processes therein, the magnetosphere–ionosphere–thermosphere (MIT) system needs to be studied as a whole.

18 Αυγ 2021 · Variations in the 11-year solar cycle as well as longer cycles are important for any future projections of the state of the atmosphere and climate. Continued observations of solar activity both for radiation and particles is vital for our understanding.
Synopsis. The thermosphere is the atmospheric region from ∼85 to ∼500 km altitude, containing the ionosphere. It is characterized by high temperature and large variability, in response to changes in solar ultraviolet radiation and solar-driven geomagnetic activity.
1 Ιαν 2023 · The thermosphere is connected to the lower atmosphere predominantly through wave mechanisms; tides (migrating and non-migrating), large-scale planetary waves, and small-scale gravity waves. Waves propagate upwards and deposit momentum and energy when they become unstable (“break”).
The thermosphere is very important for human life as it contributes enormously to protecting the earth, as well as enabling space exploration and modern forms of communication. It recycles water, absorbs the sun’s energy and creates a moderate temperature .
The thermosphere is a layer of Earth's atmosphere that is directly above the mesosphere and below the exosphere. It extends from about 90 km (56 miles) to between 500 and 1,000 km (311 to 621 miles) above Earth's surface.
NASA’s heliophysics researches the ionosphere-thermosphere-mesosphere region where our neutral atmosphere transitions into the ionized plasma of space. In this thin shell that surrounds our home planet, the atmosphere is in constant motion, shaped by the influence of both solar activity and changes in the lower atmosphere and in near-Earth space.
