Sounding rocket studies of ionospheric turbulence above Svalbard.
Show summary
Every morning between about 06 UT and 11 UT, Svalbard rotates just below the cusps (dayside aurora), where direct coupling between the solar wind, magnetosphere and ionosphere occurs. This provides a unique window to study the dayside aurora and the highly dynamic processes associated with it, examples of which include electron and ion precipitation and heating, electrostatic and electromagnetic waves, as well as turbulence.
In this work, we focus on the turbulence which, alongside with being of pure scientific interest, can also have societal impacts. Indeed, the “irregular” electron density structures associated with it can affect our technology infrastructures by for instance degrading High Frequency (HF) communication and Global Navigation Satellite Systems (GNSS) signals.
After briefly reviewing some of the mechanisms believed to be important in the development of turbulence in the high-latitude ionosphere, we present recent observations of density irregularities obtained by sounding rockets above Svalbard. We focus on measurements made as a part of the
Grand Challenge Initiative (GCI) Cusp, an international project combining sounding rockets missions and ground-based instruments to study the cusps. We show detailed characterization of the nature of the irregularities including their phase velocity and wavelengths, helping shedding light onto the process(es) involved in their formation, especially at the scales important for Space weather applications.

Modeling scintillation produced by ionospheric Kelvin Helmholtz in the cusp ionosphere using GEMINI-SIGMA.
Show summary
Ionospheric irregularities are known to cause fluctuations in radio signals called scintillation in the phase and amplitude of the complex signal. The turbulent structures responsible for the scintillation are a few hundreds of meters to few tens of kilometers scale sizes (intermediate scale sizes). With the growing interest in high latitude scintillation, we would like to investigate the effect of typical physical mechanisms on the radio scintillation.
Here we present our modeling studies of Global Positioning System (GPS) scintillation through Kelvin Helmholtz instability (KHI) in the cusp region. For modeling we use the first principles based Geospace Environment Model of Ion-Neutral Interactions (GEMINI) and Satellite-beacon Ionospheric-scintillation Global Model of the upper Atmosphere (SIGMA). We utilize a cusp event study with detailed observations from the EISCAT Svalbard Radar (ESR) and scintillations detected from a network of four Global Navigation Satellite Systems (GNSS) receivers in Svalbard. The event presents evidences of the role of magnetosphere-ionosphere coupling in the generation of plasma irregularities and scintillations in the cusp. Using numerical simulations, we investigate the potential role of the Kelvin-Helmholtz instability in producing such scintillation. Furthermore, we compare the results with characteristics of GPS scintillations associated with a polar cap patch and the gradient drift instability to deduce distinctive characteristics of the respective plasma irregularities.
