Research Abstract |
Zonal structures in the bottom of the upper atmosphere region at around 100 km altitude have been revealed by small-scale features in the airglow imaging, temperature and constituent observations by sodium lidars. We found a significant zonal variability, but at the same time, effect of latitudinal difference of several degrees can also be discussed. Two-dimensional mapping in the mesosphere and lower thermosphere will become very important in the future programs.
