Abstract: Gravity waves (GWs) play an important role in atmospheric dynamics. Especially in the mesosphere and lower thermosphere (MLT) dissipating GWs provide a major contribution to the driving of the global windsystem. The scales of GWs are often too small for most general circulation models (GCMs) to be resolved, and the effect of GWs on the global circulation has to be parameterized in the models. Therefore global observations are needed to better constrain GW parameterizations, as well as the part of the GW spectrum that is explicitly resolved in GCMs. The small scales of GWs are, however, also a challenge for global observations from space. Limb sounding is often used in satellite missions because it provides information about the middle atmosphere dynamics with a good vertical resolution. However, typical limb sounders have a poor horizontal resolution along the instruments’ line-of-sight (LOS). Conversely, nadir sounders have a better horizontal resolution, but suffer from a poor verticalresolution. For this reason, the wave structures deduced from satellite observations are limited either in vertical or horizontal resolution due to the viewing geometry. In this thesis, novel satellite-borne observation strategies are investigated for the purpose of resolving 2-D or 3-D small scale GW structures in the MLT region with unprecedented spatial resolution. ...
