Radar observations of stratified layers in the mesosphere and lower thermosphere (50–100 km)

Abstract

In this paper, observations of stratified layers in the mesosphere and lower thermosphere (50–100 km) made using radar techniques are reviewed, and relevant observations made with other techniques are briefly considered. Emphasis is given to SOUSHY VHF radar observations, and to a discussion of the importance of atmospheric gravity waves and tidal period motions in the production of layers of stratified turbulence. A brief history of radar observations of such layers is also presented.
