This chapter reviews recent findings of multi‐scale structures and dynamics in the high‐
latitude ionosphere, particularly on meso‐scale (10s‐100s km) processes, as well as their …

The correlation between the rate of TEC index (ROTI) and scintillation indices S 4 and σ Φ
for low-latitude region is analyzed in this study, using data collected from a Global …

The polar ionosphere is often characterized by irregularities and fluctuations in the plasma
density. We present a statistical study of ionospheric plasma irregularities based on the …

As societal dependence on transionospheric radio signals grows, space weather impact on
these signals becomes increasingly important yet our understanding of the effects remains …

In this study, we present global climatological distributions of ionospheric plasma
irregularities based on measurements by the Swarm satellites. These first global statistics …

Ionospheric irregularities impair Global Navigation Satellite System (GNSS) signals and, in
turn, affect the performance of GNSS positioning. Such effects are especially evident at low …

The geomagnetic storm of 17–18 March 2015 was caused by the impacts of a coronal mass
ejection and a high‐speed plasma stream from a coronal hole. The high‐latitude ionosphere …

We present two examples from the cusp ionosphere over Svalbard, where poleward moving
auroral forms (PMAFs) are causing significant phase scintillation in signals from navigation …

Small-scale ionospheric irregularities affect navigation and radio telecommunications. We
studied small-scale irregularities observed during the 22 June 2015 geomagnetic storm and …

Abstract Using the University Navstar Consortium (UNAVCO) Global Positioning System
(GPS) receiver network in North America, we present 2‐D distributions of GPS radio signal …
