Journal of Marine Science and EngineeringIn existing regional geomagnetic field modeling, the smoothness of basic functions and the insufficient data constraints in marginal regions lead to the omission of detail features and extrapolation oscillations.

Some anticipated contributions to core fluid dynamics from the GRM [PDF]
It is broadly maintained that the secular variation (SV) of the large scale geomagnetic field contains information on the fluid dynamics of Earth's electrically conducting outer core.

Hiss Wave Evolution During Substorms Based on Van Allen Probes Observations
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract Hiss waves frequently occur in the plasmasphere or plumes, playing a key role in energetic electron loss in the Earth's inner magnetosphere. While previous studies have linked hiss wave enhancements in the outer plasmasphere (just inside the plasmapause) to electron injections during substorms, their evolution across various substorm phases ...

GRM as a follow-on to MAGSAT [PDF]
MAGSAT was the first near-Earth spacecraft dedicated to measurement of the vector geomagnetic field. Its objectives were to use the vector measurements to measure and model both the main field and the crustal field of the Earth.

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract At elevated electron temperature (Te≥3000°K ${T}_{e}\mathit{\ge }3000\mathit{{}^{\circ}}\mathrm{K}$) inside Sub‐Auroral Ion Drift, resonant vibrational excitation (RVE) increases the vibrationally excited (v≥8 $v\mathit{\ge }8$) nitric oxide (NO) population in the E‐region, which undergoes overtone vibrational emissions (Δv≥8 ${\Delta }v ...

Steady induction effects in geomagnetism. Part 1A: Steady motional induction of geomagnetic chaos [PDF]
Geomagnetic effects of magnetic induction by hypothetically steady fluid motion and steady magnetic flux diffusion near the top of Earth's core are investigated using electromagnetic theory, simple magnetic earth models, and numerical experiments with ...

Decadal Stability of Multi‐Scale Core‐Mantle Boundary in Core‐Reflections of Repeating Earthquakes
Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract Temporal changes near the core‐mantle boundary (CMB) would trigger insights into ongoing thermal and chemical interactions between the Earth's core and mantle. Here, we search for multidecadal temporal changes in the CMB topography and heterogeneity using waveform similarity analysis of core‐reflected phases (PcP, ScP, and ScS) from global ...

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract Resolving the mixture of natural plasma waves and persistent spacecraft interference is a fundamental challenge in space physics, as it obstructs the analysis of wave‐particle interactions and energy transport processes. Traditional signal decomposition methods often fail to adequately separate these components due to their time‐varying ...

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.Abstract The Curie Point Depth (CPD) is a key thermal boundary in the deep lithosphere and is widely used to constrain its thermal structure. However, uncertainties in magnetization and the non‐uniqueness of inversion lead to considerable inter‐study differences.
