GLSP‐EDConvLSTM: Enhancing TEC Prediction Performance by Simultaneously Perceiving Local and Global Spatial Features

Space Weather, Volume 24, Issue 5, May 2026.
Abstract Total Electron Content (TEC) is influenced by local and global scale factors: localized effects causing fine‐grained differences in small areas, and global‐scale effects driving synchronized variations across all over the world. This underscores the necessity of modeling both global and local features for high‐performance TEC prediction.

How Does the Definition of a Geomagnetic Storm Affect the Contents of the Resulting Storm List?

Space Weather, Volume 24, Issue 5, May 2026.
Abstract A geomagnetic storm is a significant and prolonged disturbance of the Earth's magnetic field caused by an enhancement of the ring current. Storms are typically identified using magnetic field measurements from multiple ground‐based magnetometers, and the corresponding dates and times of multiple storms can be collated to form a storm list ...

Assessment of Ionospheric Model Performance Over the US During the Extreme G5 2024 Mother's Day Geomagnetic Storm

Space Weather, Volume 24, Issue 5, May 2026.
Abstract This study evaluates 17 ionospheric models' performance over the Continental United States (CONUS) during the 2024 Mother's Day geomagnetic storm, using ground‐based GNSS Total Electron Content (TEC) and single‐frequency (SF) precise Single Point Positioning (SPP) technique. The storm produced significant positive storm effects during its main

Smartphone Carrier Phase TEC: A Study Across Ionospheric Spatio‐Temporal Scales

Space Weather, Volume 24, Issue 5, May 2026.
Abstract This study explores the potential of dual‐frequency smartphones as accessible tools for citizen science in ionospheric research. While prior work by Smith et al. (2024, https://doi.org/10.1038/s41586‐024‐08072‐x) demonstrated global ionospheric monitoring using aggregated pseudorange Total Electron Content (TEC) data from millions of Android ...

Leveraging Legacy Broadband Magnetotelluric Data for Geoelectric Field Hazard Assessment in Southern Italy

Space Weather, Volume 24, Issue 5, May 2026.
Abstract Geomagnetically induced currents (GICs) are a significant space weather hazard. Their accurate assessment requires estimating the geoelectric field, which depends on the Earth's subsurface electrical conductivity. While long‐period magnetotelluric (MT) surveys are ideal, archives of legacy broadband MT data, originally acquired for geological ...
