Ionospheric Variability and Geomagnetic Storms

Global Behavior of Ion TEC Anomalies

The Earth's ionosphere is a dynamic region of the atmosphere affected by various space weather phenomena. The ionospheric total electron content (TEC) is a crucial parameter for understanding ionospheric variability and its impact on radio wave propagation. This paper presents a study of the global behavior of ionospheric TEC anomalies during solar cycles 24 and 25.

Spatial and Temporal Analysis

The study employed advanced analysis techniques to examine the spatial and temporal aspects of ionospheric variability. Data from multiple global ionospheric stations was utilized to capture a comprehensive picture of the ionosphere's response to geomagnetic storms. The analysis focused on identifying patterns and trends in TEC variations and their correlation with geomagnetic activity.

Geomagnetic Storm Effects

The study particularly explored the effects of a moderate geomagnetic storm that occurred in late March 2023. This storm had a significant impact on the ionosphere, causing substantial TEC disturbances and disruptions in radio communication systems. The research provides insights into the immediate and long-term impacts of geomagnetic storms on the ionosphere and highlights the need for monitoring and mitigation strategies.

Conclusion

The findings of this study contribute to our understanding of ionospheric variability and its connection to geomagnetic storms. The results have implications for the effective operation of satellite-based communication systems, over-the-horizon radar networks, and other applications that rely on ionospheric conditions. Further research in this area is essential to improve space weather forecasting and enhance our resilience to ionospheric disturbances.
