Calibration and Fusion of GOLD‐Inferred TEC Data With Ground‐Based TEC
Abstract Ground‐based Global Navigation Satellite System (GNSS) receivers provide primary total electron content (TEC) measurements used to monitor ionospheric variability, yet their sparse distribution over oceanic and equatorial regions limits global coverage and model accuracy.

On the Role of Electron Precipitation in Excess Radiation Doses Measured at Aviation Altitudes
Abstract Radiation from space in the form of galactic cosmic rays (GCRs) generates a persistent background of ionizing radiation in Earth's atmosphere. The dose rate of ionizing radiation due to GCRs increases from sea level to aviation altitudes.

Multi‐Wavelength Transformer‐Based 24‐Hour Solar Flare Forecasting at the Active‐Region Level
Abstract Solar flare forecasting remains challenging due to the complex spatiotemporal evolution of solar active regions (ARs) and the severe class imbalance associated with high‐impact events. In this work, we investigate a transformer‐based framework for active‐region–level solar flare forecasting using short sequences of multi‐wavelength ...

Investigating Potential Benefits of Future Sub‐L1 Missions With STEREO‐A
Abstract We present the first statistical study of geomagnetic storm forecasting using in situ data from the STEREO‐A spacecraft as a sub‐L1 monitor. Between November 2022 and June 2024, STEREO‐A crossed the Sun–Earth line, covering longitudinal and radial separations of ±15° $\pm 15{}^{\circ}$ from the Sun–Earth line and 0.01–0.06 au from Earth.

Comprehensive Validation of Novel Deep Learning Architectures to Forecast Geomagnetic Substorms
Abstract Magnetic substorms are disturbances in the terrestrial magnetosphere that can have significant space weather impacts, although forecasting their onset accurately remains an open problem. In this study, we develop multiple novel machine learning architectures based on convolutional neural networks, long short‐term memory networks, extreme ...
