Space Weather, Volume 23, Issue 5, May 2025.Abstract We developed a deep convolutional neural network‐based program code that automatically detects equatorial plasma bubbles (EPBs), segments EPB morphologies, and then extracts their features (including EPBs' northernmost foot latitudes and zonal drift velocities) from OI 630 nm airglow images.

Space Weather, Volume 23, Issue 5, May 2025.Abstract In this paper, we developed an efficient regional three‐dimensional data assimilation model focused on the middle‐to‐high latitude ionosphere in the Northern Hemisphere. The model employed the Empirical Canadian High Arctic Ionospheric Model (E‐CHAIM) as the background, which was specifically optimized for high‐latitude applications and has ...

Space Weather, Volume 23, Issue 5, May 2025.Abstract The enhanced variation of the magnetic field during severe to extreme geomagnetic storms induces a large geoelectric field in the subsurface. Grounded infrastructure can be susceptible to geomagnetically induced currents (GICs) during these events.

Global Sporadic‐E Prediction and Climatology Using Deep Learning
Space Weather, Volume 23, Issue 5, May 2025.Abstract Sporadic‐E Es $\left({E}_{s}\right)$ is an ionospheric phenomenon defined by strong layers of plasma which may interfere with radio wave propagation. In this work, we develop deep learning models to improve the understanding of Es ${E}_{s}$, including the presence, intensity and height of the layers. We developed three separate models.

Solar Cycle and Seasonal Dependences of Field‐Aligned Currents
Space Weather, Volume 23, Issue 5, May 2025.Abstract Enhancements of Birkeland field‐aligned currents (FACs) have been reported during magnetospheric substorms and geomagnetic storms. While FACs related to geomagnetic disturbances have been extensively studied, the long‐term variations of FACs remain less explored.

Geophysical Research Letters, Volume 52, Issue 8, 28 April 2025.Abstract Traveling ionospheric disturbances (TIDs) driven by a large number of internal and external sources are detectable with dense networks of ground‐based Global Navigation Satellite System (GNSS) receivers' measurements of total electron content (TEC).
