Gravity waves play a significant role in the structure and dynamics of the Earth's upper atmosphere. In the mesosphere, at 80–100 km, there are several naturally-occurring airglow emissions that can be used as dynamical tracers of winds, temperatures, etc. In this talk, I will give a general background on what mesospheric gravity waves are and how they behave. I will also discuss the use of optical instrumentation to investigate these disturbances and then present a number of interesting case studies.
