The use of geomagnetic field models in magnetic surveys [PDF]
The importance of global geomagnetic field models for the reduction of magnetic surveys is discussed. It is demonstrated that a numerical model with adequate secular variation correction, provides a suitable representation of the regional field.

Forecasting the geomagnetic activity of the Dst Index using radial basis function networks [PDF]
, 2006 The Dst index is a key parameter which characterises the disturbance of the geomagnetic field in magnetic storms. Modelling of the Dst index is thus very important for the analysis of the geomagnetic field.

Cryptic Paleomagnetic Complexity in the Ediacaran Egersund Dikes
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract The Ediacaran Period (∼635–539 Ma) represents a critical interval in Earth's evolution, yet its paleomagnetic record remains complex and contentious. One of the few Ediacaran paleomagnetic results from Baltica considered robust is a pole from the ca.

Ediacara Obscura: Unveiling Hidden Magnetisations in the Fen Complex, Southern Norway
Geochemistry, Geophysics, Geosystems, Volume 27, Issue 5, May 2026.Abstract Paleomagnetic directions found in Ediacaran (635–539 Ma) rocks are widely dispersed, which has led to conflicting hypotheses about tectonic regimes and geomagnetic field behavior during this period, and raised doubts about the fidelity of the paleomagnetic record.

THE METHOD TO SOLVE DRIFT IN MAIN GEOMAGNETIC FIELD
Proceedings of the Mongolian Academy of Sciences, 2016 The method to solve the velocity of drift in MGF is written in this paper. This method is based on the dynamo theory for geomagnetic field. The velocity of drift in the main geomagnetic field is also solved from the condition that the power variation of ...

Drivers of Mid‐Latitude Quiet‐Time Longitude Variations in Ionospheric Density
Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.Abstract The aim of this study is to provide an observational benchmark of mid‐latitude quiet‐time variability in winds, O/N2, and TEC across longitude and local time to provide a foundation for future model–data comparison studies. The quiet‐time ionospheric structure is not uniform but rather exhibits pronounced longitudinal and local‐time ...

The causes of recurrent geomagnetic storms [PDF]
The causes of recurrent geomagnetic activity were studied by analyzing interplanetary magnetic field and plasma data from earth-orbiting spacecraft in the interval from November 1973 to February 1974.

WACCM‐X Simulation of the Atmosphere From 1950 Through 2024 at an Hourly Resolution
Journal of Geophysical Research: Space Physics, Volume 131, Issue 5, May 2026.Abstract Modeling of the upper atmosphere, namely the thermosphere and ionosphere, is becoming important for applications such as orbital propagation (including satellite collision avoidance), radio propagation for communications, radar and position, navigation and timing.
