Reviews of Geophysics, 1995
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.

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 ...

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.

Ground state of the thermosphere and substorm time thermospheric response
The thermospheric composition (O/N2 ratio and NO) condition represents the state of the thermosphere. Significant changes in thermospheric composition and neutral wind are often observed during non-storm time (e.g. a weak substorm on May 29, 2023) due to continous energy and momentum input from solar wind to the geospace.  It is challenging toYongliang Zhang +4 more

Nitric oxide in the lower thermosphere
Planetary and Space Science, 1992Abstract Satellite measurements of nitric oxide in the lower thermosphere (100–120 km) show the density to be highly variable. The variation at low latitudes is correlated with solar activity and the variation at polar latitudes is connected with geomagnetic activity. A study of a one-dimensional, photochemical model shows that calculations of nitric

Abstract The Earth's mesosphere and lower thermosphere are the least explored regions of the Earth's atmosphere. The observations that have been made in this region, however, indicate that it is a dynamically active region, especially the polar lower thermosphere where most of the auroral energy that impacts the Earth's atmosphere is deposited.

Chemistry in the Thermosphere and Ionosphere
Chemical & Engineering News Archive, 1986The thermosphere is that rarefied portion of our atmosphere, lying between 80 and 500 km above Earth's surface, where the temperature increases dramatically with altitude. Many satellites orbit in the upper thermosphere, experiencing a drag that eventually brings them down to burn up in the lower atmosphere.

Energetics of the midlatitude thermosphere
Journal of Atmospheric and Terrestrial Physics, 1976Thermospheric energetics is examined from the point of view of atomic and molecular processes which convert solar EUV radiative energy into kinetic energy of the ambient electron, ion, and neutral gases. The energy flow from photon to photoelectron-ion pair through energy loss and ion-molecule transfer to eventual electron-ion recombination is traced ...
