The Earth is surrounded by a blanket of air, called the atmosphere. The atmosphere is a thin layer of gases that envelope the Earth. The gases are held close to the earth by gravity and the thermal movement of air molecules. Life on Earth is supported by the atmosphere, solar energy, and the magnetic fields.

Reviews of Geophysics, 1975
The period 1971–1974 has been marked by a substantial advance in man's understanding of composition variability in the thermosphere. The global view of the atmosphere that has been provided by satellite observations in concert with radar backscatter measurements has shown a pattern of composition variability that theorists have been able to explain in ...

Many people believe that the region of space familiar for visions of astronauts floating about their work outside a space shuttle cargo bay is empty, nothing, a vacuum. Contrary to popular opinion, the Earth's atmosphere extends even beyond that place where shuttle crews release, repair, or retrieve satellites.

Abstract We have reexamined the aeronomic model of Titan's thermosphere by A.J. Friedson and Y.L. Yung ( J. Geophys. Res. 89, A1, 85–90). Our computations disagree with theirs on the evaluation of the solar heating profile. We attribute this discrepancy to a numerical error in their code.

Global Thermospheric Modelling
Physica Scripta, 1987Reviewing observations of the thermosphere, one may obtain a first impression of bewildering, even chaotic, variations of basic parameters such as the density, composition, temperature and wind velocity. Ordering these observations by altitude, geographic and geomagnetic location, local and Universal Time, by considering the season, and the evolution ...

The capabilities of the global‐scale wave model (GSWM) [Hagan et al., 1995, 1999] are extended to include migrating thermospheric solar tides. The GSWM thermospheric tidal forcing parameterization is based on neutral gas heating calculated from first principles in the National Center for Atmospheric Research (NCAR) thermosphere/ionosphere ...

Thermospheric superrotation revisited
Journal of Geophysical Research: Space Physics, 1984A theoretical spectral model is presented to describe the mean (zonally averaged) circulation and latitudinal distributions in the temperature and composition. The results show that solar differential heating by radiation at low latitudes and Joule dissipation at auroral latitudes are primarily responsible for the observed temperature and density ...

Poststorm Thermospheric NO Overcooling?
Journal of Geophysical Research: Space Physics, 2020AbstractA mechanism of the neutral gas density decrease at middle latitudes during the recovery storm phase is discussed. The recently proposed method to retrieve thermospheric parameters from ionospheric observations is used for the analysis of equinoctial, summer, and winter severe magnetic storms.

The influence of thermal conductivity on the temperature distribution in the thermosphere is discussed. It is inferred that the temperature gradient probably falls off rapidly above the base of the F 1 layer instead of remaining almost constant up to great altitudes, as is often assumed.

Abstract A brief review is given of our current understanding of the atmospheric perturbations in the thermosphere and exosphere that are related to geomagnetic disturbances and of current efforts to represent these in empirical models of the upper atmosphere.
