Estimating Transmissivity From the Water Level Fluctuations of a Sinusoidally Forced Well
… methods with additional field data is suggested. Atmospheric tides and earth tides can cause the water level in a well to oscillate in a sinusoidal fashion. Two new methods for estimating transmissivity (T) from the analysis of these water-level oscillations were developed. The goal of this thesis …

Development of ground and space based instrumentation for middle and upper atmospheric studies
… with this system is to obtain measurements of atmospheric tides, planetary and gravity wave amplitudes and phase in the lower thermosphere. Measurement of waves into the lower thermosphere is accomplished using Rayleigh lidar methods with high power-aperture (PA) products using new technology …

Satellite Constellation Optimization for In-Situ Sampling and Reconstruction of Tides in the Thermospheric Gap
… within it interact is essential for predicting atmospheric shifts relevant for spaceflight, the evolution of Earth's climate, radio communications, and other practical applications. In-situ observations of a critical altitude region within Earth's atmosphere from 100-200 km in altitude, a subset …

Vertically Propagating Tides in the Martian Atmosphere
Atmospheric tides significantly influence the dynamics of Mars' upper atmosphere. The impact of tides on the mean state of the present-day Martian atmosphere is especially large at high altitudes. Certain tides can propagate away from the region of generation in the lower atmosphere and reach the …

Long-term investigation of the lunar tide in the equatorial electrojet during stratospheric sudden warmings
… upper atmosphere. Such an interaction between atmospheric layers is known as vertical coupling. During geomagnetically quiet times, when near-Earth space is not under the influence of solar storms, these processes become important drivers for ionospheric variability. Studying the link between …
