Midlatitude thermospheric wind and temperature: networked Fabry-Perot interferometer observations and radiative transfer modeling
… First, we describe an algorithm which estimates thermospheric line-of-sight wind and temperature from raw FPI data. This new algorithm has the advantage over previous work in that it provides accurate temperature estimates and uncertainties. We then present a novel regularization-based technique …

Recommissioning REDDI: Reviving a Doppler Asymmetric Spatial Heterodyne Spectrometer for Observing Thermospheric Winds
… spectrometer could be used to accurately measure thermospheric winds by observing the Doppler shift of the 630nm emission of oxygen in the thermosphere. In 2015, we began a project to redesign the input optics of REDDI to repurpose the instrument from a demonstration unit to a long duration …

Parameter estimation in imaging Fabry-Perot Doppler spectroscopy
… advance the precision and accuracy of estimated thermospheric wind velocities and temperatures. This dissertation starts with derivations of analytical formulas for uncertainties in parameters estimated by fitting a profile of a Gaussian emission line with an unknown background component. The …
