| Summary: | Submission note: A thesis submitted in total fulfilment of the requirements for the degree of Doctor of Philosophy to the School of Engineering and Mathematical Sciences, Faculty of Science, Technology and Engineering, La Trobe University, Bundoora. The aim of this project was to test the hypothesis that small spatial scales (on the order of 500 km or less) play an important role in thermospheric dynamics. To achieve this, a new all-sky scanning, imaging Fabry-Perot spectrometer was built at La Trobe University and installed at Mawson station, Antarctica (67◦360 S, 62◦520 E, Inv 70◦300 S, Magnetic Midnight: 2240 UT). This instrument was capable of recording independent spectra from 61 locations simultaneously across a 144◦ full-angle field-of-view, with a maximum time resolution of ∼2 minutes. Data from this instrument was combined with that from a narrow-field (6◦ full-angle), imaging Fabry-Perot spectrometer operating at Davis station (68◦350 S, 77◦580 E, Inv 74◦360 S, Magnetic Midnight: 2200 UT).
