Abstract
In the last 15 years, the middle-upper-atmosphere lidar observations have evolved from narrow altitude ranges to the significantly extended altitude ranges of neutral profiling from near the ground up to ~200 km and of ion detection up to ~300 km. A latest development was the first detection of helium to ~700 km. These results demonstrate the huge potentials that lidars bring to the ionosphere-thermosphere-mesosphere-stratosphere (ITMS) physics research as well as to the plasma-neutral coupling studies in the near space environment. This chapter highlights several stunning discoveries made from lidar measurements, including the thermosphere-ionosphere metal (TIMt) layers, full coverage of gravity wave temporal spectrum, and multistep vertical coupling, to illustrate the significant progresses in atmosphere-space sciences. Then we focus on identifying future lidar technologies in enabling cutting-edge sciences in the ITMS physics and interactions between plasma space and neutral atmosphere.
