TL;DR: In this article, it was demonstrated that observed saturation spectra are not solely due to individually saturated waves but most likely result from amplitude limiting instabilities arising from wave superposition, and that, while the spectrum is saturated at large wavenumbers, the total kinetic energy per unit mass and the characteristic vertical wavelength increase with altitude.

TL;DR: In this article, a study of the frequency spectra, the vertical profiles of energy density, and the momentum flux of the motion field observed during a six-day campaign in March 1986 using the MU Radar in Shigaraki, Japan is described.

TL;DR: In an attempt to overcome some of the deficiencies of existing meteoroid models, NASA's Space Environments and Effects (SEE) Program sponsored a 3-year research effort at the University of Western Ontario.

TL;DR: A shuttle-based component of NASA's Mission to Planet Earth, the Atmospheric Laboratory for Applications and Science (ATLAS), completed its second mission making detailed measurements of Earth's middle atmosphere and solar input in April 1993 as discussed by the authors.

TL;DR: In this paper, a study of the azimuthal anisotropy of the motion field observed during a six-day campaign in March 1986 using the MU radar in Shigaraki, Japan is presented.
