Observations and Modeling of Scintillation in the Vicinity of a Polar Cap Patch

Small-scale ionospheric plasma structures can cause scintillation in radio signals passing through the ionosphere. The relationship between scintillated signal and how structuring develops is complex. We model development of small-scale around an idealized polar cap patch observed by Resolute Bay Incoherent Scatter Radars (RISR) with Geospace Environment Model for Ion-Neutral Interactions (GEMINI). Then, we simulate a resulting Satellite-beacon Ionospheric-scintillation Global upper Atmosphere (SIGMA) to predict characteristics that will be ground receiver at different stages instability development. Finally, compare predicted actual observations from receivers vicinity Bay. interpret results terms nature ionosphere it impacts frequencies, attempt infer information about irregularity spectrum.
