Special Issue Information

Dear Colleagues,

Understanding the processes occurring in the Earth’s ionosphere is of utmost importance to characterizing several phenomena with relevance to space weather. In fact, the ionospheric plasma promptly reacts to variations in magnetic and electric fields and, thus, is particularly sensitive to different processes on a wide range of spatial and temporal scales. These variations may substantially affect, for instance, the physical properties of the ionosphere, its energetic balance, and the propagation of electromagnetic signals throughout the ionospheric layers.

Thanks to the increased volume of high-quality data, these features can now be reliably investigated due to the joint effort of remote sensing and in situ facilities, such as ionosondes, radars, satellites, and GNSS receivers. This Special Issue aims to encourage advances in our knowledge of the ionosphere through the use of complementary data with different origins and their comparison via models.

This Special Issue is the third edition of ‘Ionosphere Monitoring with Remote Sensing’, and we intend to proceed built upon previous research results. Contributions may address, but are not restricted to, the following topics:

  • The impact of sunlit, solar and geomagnetic activity on the ionosphere at all latitudes;
  • The impact of ionospheric variations on technology;
  • Improvements and new constraints of ionospheric models through new observations, analyses and techniques;
  • Investigating the magnetosphere–ionosphere coupling through different multi-instrumental approaches;
  • New instruments, missions and tools to monitor the ionosphere.

Space plasma turbulence plays a relevant role in several plasma environments, such as solar wind and the Earth’s magnetosphere–ionosphere system, and is essential for describing their complex coupling. This interaction gives rise to various phenomena, including ionospheric irregularities and the amplification of magnetospheric and ionospheric currents. The structure and dynamics of these currents have relevant implications, for example, in studying ionospheric heating and the nature of electric and magnetic field fluctuations in the auroral and polar environments. In this study, we investigate the nature of small-scale fluctuations characterizing the ionospheric magnetic field in response to different geomagnetic conditions. We use high-resolution (50 Hz) magnetic data from the ESA’s Swarm mission, collected during a series of high-latitude crossings, to probe the scaling features of magnetic field fluctuations in auroral and polar cap regions at spatial scales still poorly explored. Our findings reveal that magnetic field fluctuations in field-aligned currents (FACs) and polar cap regions across both hemispheres are characterized by different scaling properties, suggesting a distinct driver of turbulence. Furthermore, we find that geomagnetic activity significantly influences the nature of energy dissipation in FAC regions, leading to more localized filamentary structures toward smaller scales.
