Abstract 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 F1 layer instead of remaining almost constant up to great altitudes, as is often assumed.

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.

Analysis of rocket-borne mass spectrometric thermospheric measurements of major and minor neutral species by coupled multicomponent equations of motion reveals the lower thermosphere to be in a nonequilibrium state. The individual species motion and thermal diffusion are significant factors in (1) the theoretical calculations of self-consistent species

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 ...

From Lotosphere to Thermosphere
2017This paper reflects on the influential nature of some of the many scientific achievements linked to Ed Brinksma on the occasion of his 60th birthday. We in particular discuss pioneering contributions in the contexts of constraint-oriented specification, model-based testing, and cost-optimal timed reachability, as well as with respect to tools and ...
