Abstract
Investigating the Spatial Scales of Ionospheric Irregularities Using Wavelet Analysis: Ionospheric radio wave scintillation arises from plasma density irregularities in Earth’s ionosphere. Consequently, rapid fluctuations occur in the phase and amplitude of Global Navigation Satellite System (GNSS) signals and can impact communication and navigation systems. These irregularities span from a wide range of spatial and temporal scales and evolve dynamically under the influence of magnetosphere-ionosphere (MI) processes. We investigate phase and amplitude scintillation events using Continuous Wavelet Transform (CWT) to study the spatial evolution of ionospheric irregularities. These irregularities are thought to be formed via different plasma mechanisms such as precipitation, gradient-drift instability (GDI), etc. They can cascade from large-scale to small-scale density structures or vice versa, causing different patterns/signatures in their temporal forms observed on the ground GNSS measurements. The expected outcome is a validated analytical approach and a strong foundation to study the underlying plasma processes and the evolution of plasma structures. This work contributes to improving diagnostic methods for ionospheric variability and its effects on radio wave propagation.
