Automated Detection and Analysis of Low Latitude Nightside Equatorial Plasma Bubbles
Equatorial plasma bubbles (EPBs) are large structures consisting of depleted plasma that generally form on the nightside of Earth's ionosphere along magnetic field lines in the upper thermosphere/ionosphere. While referred to as `bubbles', EPBs tend to be longer along magnetic latitudes and …

Evaluating the Capability of ICON-MIGHTI to Detect Plasma Bubbles in the Ionosphere
… day-to-day brightness potentially indicative of plasma bubbles: regions of low-density E-region plasma which rise through the F-region and cause radio scintillation that interferes with communications and GPS performance. Here, we explore the possibility of MIGHTI observing plasma bubbles by …

Tomographic Imaging and Characterization of Ionospheric Equatorial Plasma Irregularities With the Global Ultraviolet Imager
The experimental aspect explores the equatorial plasma bubble imaging capabilities of this technique and its scientific impact. Retrievals of altitude and longitude profiles allow for characterization of plasma bubbles based on their structure and depth of depletion. This information can then be …

Techniques for automated classification of nighttime ionospheric images
… of interest are those that contain equatorial plasma bubbles (EPB) or medium-scale traveling ionospheric disturbances (MSTID). However the majority of the images collected contain neither EPBs nor MSTIDs, or are contaminated by other light sources or clouds. In order to identify the images of …

GNSS-based Hardware-in-the-loop Simulation of Spacecraft Formation Flight: An Incubator for Future Multi-scale Ionospheric Space Weather Studies
… and polar space weather structures (e.g. plasma bubbles, tongues-of-ionization) were successfully simulated in 4-dimensional ionospheric scenarios on the enhanced VTFFTB. The dissertation has demonstrated the VTFFTB is a versatile GNSS-based SFF mission incubator to study ionospheric space …

Spatial Resolution of Equatorial Plasma Depletions Using Variable-Range Time-Delay Integration
Previous plasma imaging missions have used time-delay integration techniques that correct for uniform motion blur during integration. This was due to the assumed constant range-to-target of each pixel in the observed scene. ICON's low orbital altitude and twelve second integration time create …
