Ionospheric Response to the 8 April 2024 Total Solar Eclipse: Plasma Depletion and Eclipse‐Driven MsTIDs

Space Weather, Volume 24, Issue 4, April 2026.
Abstract The total solar eclipse on 8 April 2024 provided a unique opportunity to investigate the three‐dimensional (3‐D) ionospheric response under enhanced solar activity over North America. In this study, we processed high‐density GNSS observations from ∼1,700 stations to derive vertical total electron content and applied a multi‐term sinusoidal ...

The Real‐Time Advanced Ionospheric Data Assimilation (AIDA) Model

Space Weather, Volume 24, Issue 2, February 2026.
Abstract The Advanced Ionospheric Data Assimilation (AIDA) is a real‐time data assimilation model of global 3D ionosphere and plasmasphere electron density. Changes in the local space environment can occur on very short timescales, particularly during disturbed geomagnetic conditions.

Global Ionospheric Slab Thickness Prediction Model Using XGBoost and Ensemble Learning

Space Weather, Volume 24, Issue 1, January 2026.
Abstract The ionospheric equivalent slab thickness is a key parameter for understanding the plasma distribution in the ionosphere, with direct relevance to satellite navigation, communication, and skywave over‐the‐horizon radar. However, traditional prediction methods often suffer from regional biases, limiting their global applicability.
