Upper, middle, and lower atmosphere coupling
 The middle atmosphere is influenced by the energy transfer from both above and below. The former is caused by solar wind-magnetosphere interaction, and the latter originates from disturbances in the lower atmosphere and is carried by the upward propagation of atmospheric waves. The coupling processes in these atmospheric regions are studied by measuring the wind and temperature fields, and the minor atmospheric constituents using advanced optical instruments (Fabry-Perot imager, aurora spectrograph, lidar), radars (EISCAT, meteor wind radar, MF radar, HF radar) and stratospheric balloons, as well as numerical analyses and computer simulations.
