A Long‐Term Study of the Variability of Polar Cap Patches Using Advanced Modular Incoherent Scatter Radars (AMISRs) Open
The polar cap ionosphere is a dynamic and intricately structured environment that plays host to polar cap patches (PCPs) and other mesoscale density formations. These phenomena can lead to the emergence of smaller‐scale structures through …

Examining the Power Law Relationship Between Absorption and Frequency Using Spectral Riometer Data Open
High frequency radio wave propagation is sensitive to absorption in the D and lower E‐region ionosphere. Absorption models typically characterize attenuation expected at 30 MHz, meaning scaling relationships are required to map to absorpti…

A Canadian perspective on the May 2024 space weather event Open
The May 2024 space weather disturbance is the latest (as of the time of writing) in a series of space weather events going back to 1859 that have documented impacts on critical infrastructure and technologies. Impacts on these systems rang…

High‐Latitude Off‐Great Circle Propagation Associated With the Solar Terminator Open
Large‐scale ionospheric gradients associated with the solar terminator can deflect high frequency (HF) radio waves to off‐great circle paths during the morning and evening, negatively impacting technologies reliant on HF radio wave propaga…

Use of Terrestrial High Frequency Signals in Riometer Data to Explore the Size of D‐Region Electron Density Enhancements Open
This paper presents the first observations from the prototype Space Weather Adaptive Network (SWAN) riometers, which are capable of simultaneous measurements of narrow‐band terrestrial signal power and Cosmic Noise Absorption (CNA). We des…

Statistical Analysis of Off‐Great Circle Radio Wave Propagation in the Polar Cap Open
High latitude ionospheric density structures such as polar cap patches and arcs are capable of deflecting high frequency (HF) radio waves to off‐great circle paths, and are likely detrimental to technologies dependent on HF radio propagati…

Frequency Management System (FMS) for Over-the-Horizon Radar (OTHR) Using a Near-Real-Time Ionospheric Model Open
Sky-wave over-the-horizon radar (OTHR) propagates radio waves off the ionosphere to provide long-range surveillance around the Earth's curvature. Frequency selection for high-latitude and polar OTHRs is challenging unless there is an envir…

Planar Structures in the Solar Wind and Their Effect on the Magnetosphere Open
This thesis is comprised of three studies which all concern implications of planar structuring in the solar wind. The first study presents a statistical comparison of various methods of determining solar wind phase front orientation for us…

Using Mutual Information to Determine Geoeffectiveness of Solar Wind Phase Fronts With Different Front Orientations Open
The geoeffectiveness of solar wind shocks depends on angle with respect to the Sun‐Earth line, with highly angled solar wind shocks being less geoeffective than nearly frontal solar wind shocks. However, it is unclear whether this holds fo…

Inverse electron energy dispersion from moving auroral forms Open
Numerous published examples of energy‐dispersed bursts show electron energies reaching as high as several keV and decaying to lower energies over a fraction of 1 s. This signature has been interpreted by some authors as due to impulsive ac…
