Abstract Metal atom and ion layers, containing such elements as Fe, Mg, Na, K, Ca, Li, originating from meteors are valuable tracers of the Earthʼs upper atmosphere. A resonance scattering lidar is a powerful remote sensing technique being applied to the upper atmospheric studies, which can measure the vertical distri- butions of temperature and wind as well as density in the metal layers. Among the observations of the mesosphere and lower thermosphere region by resonance scattering lidars, this present paper introduces the evolution and recent trends of the observations, especially those of the atmospheric phenomena pecu- liar to the polar regions, which have been conducted in the Antarctic region. |
