TLDR
In this article, a series of measurements of neutral atmospheric wind velocity, turbulent structure, temperature and density were made during each launch between 90 and 250 km altitude, combining the experimental techniques of the two groups involved.Abstract:
Two Skylark rockets were launched from Woomera rocket range, Australia (31 degrees S) on the morning and evening of 31 May 1968. Coordinated series of measurements of neutral atmospheric wind velocity, turbulent structure, temperature and density were made during each launch between 90 and 250 km altitude, combining the experimental techniques of the two groups involved. This paper attempts to construct from the combined measurements made on these occasions a dynamic picture of the interactions of atmospheric structure, and to relate the observations to previous results obtained by ourselves and other workers.read more

Simultaneous observations of E-region irregularities by ground-based and rocket-borne techniques

TL;DR: In this article, the power spectra of electron current variability were shown to be white above about 90 km, and the results are therefore tentatively interpreted as due to the decay of ion acoustic waves generated by plasma instabilities in the auroral electrojet.

Channing P. Philbrick,Channing P. Philbrick,Fan Yang,Fabio Vargas,Gary R. Swenson,Alan Z. Liu +5 more
TL;DR: In this article, a method of measuring atmospheric turbulence from resonance-fluorescence lidar observations of atmospheric Na layer density fluctuations, which is used to characterize turbulent eddy diffusion ( k z z T u r b ) from 85-km to 105-km altitude over the Andes Lidar Observatory (ALO) in Cerro Pachon, Chile, at timescales between 12-seconds and 78-seconds.

The theory of homogeneous turbulence
TL;DR: In this article, the kinematics of the field of homogeneous turbulence and the universal equilibrium theory of decay of the energy-containing eddies are discussed. But the authors focus on the dynamics of decay and not on the probability distribution of u(x).

Variations in exospheric density at heights near 1100km, derived from satellite orbits
G. E. Cook,Diana W. Scott +1 more
TL;DR: In an earlier paper as mentioned in this paper, values of exospheric density were obtained from the orbit of Echo 2 for the years 1964-1965, and the results indicated a semi-annual variation in density by a factor of between 2 and 3, considerably larger than predicted by existing atmospheric models.
