HF Heating Effects as Seen From Below and Above: First Results of Joint SURA–Ionosfera‐M Experiment

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract This paper presents the first results of a coordinated experiment on the ionospheric plasma response to high‐frequency (HF) overdense heating, conducted using the SURA heating facility and the Ionosfera‐M satellite. The experiment combined ground‐based observations with in situ satellite measurements, enabling a comprehensive study of ...

Global Cowling Effects in the Sq‐EEJ Current System Under Electrostatic Approximation: Theoretical Simulation

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract The solar quiet (Sq) current and equatorial electrojet are widely known as one of the fundamental currents in ionosphere. Although the Sq‐EEJ current system has been extensively investigated, the manner in which Hall and Pedersen current components collectively organize the system has not been clearly described.

Post‐Sunset Merging of Equatorial Ionization Anomaly Crests Into a Single Peak Over ∼35° Longitude During the 19 January 2026 Geomagnetic Superstorm

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract We investigate the nighttime equatorial ionosphere during the 19 January 2026 geomagnetic storm using Global‐scale Observations of the Limb and Disk OI 135.6 nm observations and ground‐based GPS Total Electron Content. The observations reveal a pronounced longitudinal asymmetry in the post‐sunset equatorial ionization anomaly (EIA).

Global Plasmaspheric Refilling Rates Inferred From Deep‐Learning Electron Density Reconstructions

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract As a key process in magnetosphere‐ionosphere coupling, plasmaspheric refilling is a long‐standing focus in space physics. In this study, we develop a global electron density (GEO‐NE) model based on a CNN‐Transformer architecture, and use the model to investigate plasmaspheric electron density refilling rates. Using global electron density maps
