Availability of geomagnetic information

Strategos, 2023
The issue of public availability of the Earth’s magnetic field data is not adequately regulated. The paper presents a proposal to declare geomagnetic information publicly available only when its reliability drops to the reliability of the currently best ...

Enhancement of Magnetic Flux Transferred to the Magnetotail Due to a Storm‐Time Kelvin‐Helmholtz Instability

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Along the flank magnetopause, magnetosheath flow interfaced with the relatively stationary magnetosphere produces strong flow shears, and the Kelvin‐Helmholtz instability (KHI) occurs. When the interplanetary magnetic field (IMF) is southward, anti‐parallel day‐side reconnection and KHI can interact, which may enhance the reconnection rate as ...

Investigation of the westward drift of the earth’s main geomagnetic field based on the spatial distribution of secular variation derived from IGRF-14 [PDF]

E3S Web of Conferences
Westward drift of the Earth's magnetic field is an important manifestation of geomagnetic secular variation and provides information on fluid dynamics within the outer core.

HVDC-DNN-MFO: Classifying High-Voltage Direct Current Interference Events in Geomagnetic Field Observation Data Using Deep Neural Network and Moth-Flame Optimization Algorithm

IEEE Access
Geomagnetic field observation data are valuable resources for seismic geomagnetic research. However, the construction of subways, light railroads, and high-voltage direct current transmission lines in recent years has seriously affected the output data ...

The driving mechanisms of particle precipitation during the moderate geomagnetic storm of 7 January 2005 [PDF]

, 2007
International audienceThe arrival of an interplanetary coronal mass ejection (ICME) triggered a sudden storm commencement (SSC) at ~09:22 UT on the 7 January 2005. The ICME followed a quiet period in the solar wind and interplanetary magnetic field (IMF).

Geochronological reconstruction of the Lateglacial deglaciation in the Arve Valley (Northern French Alps)

Journal of Quaternary Science, Volume 41, Issue 7, Page 1020-1035, October 2026.
ABSTRACT The timing and spatial patterns of glaciers retreat in the Northern French Alps during the Lateglacial (19.0–11.7 ka) remain debated, reflecting discrepancies among available chronological data sets. The complex interactions between major glaciers, such as the Rhône and Arve glaciers to the north and the Isère glacier to the south, represent a

Neural network prediction of geomagnetic activity: a method using local Hölder exponents [PDF]

, 2002
Local scaling and singularity properties of solar wind and geomagnetic time series were analysed using Hölder exponents . It was shown that in analysed cases due to the multifractality of fluctuations, α changes from point to point.

Models of Present and Past Geomagnetic Core Field Evolution [PDF]

Journal Of The Geological Society Of India
ABSTRACT The main geomagnetic field originates in Earth’s outer core and shields our habitat against solar wind and cosmic radiation. Global descriptions of the field evolution are provided by data-based models. Such models are available for time spans from a few years to the past 100 kyr and some geomagnetic field polarity excursions ...

Palaeosecular variations of the geomagnetic field in Africa during the Holocene: a review

, 2020
The importance of the full understanding of the Holocene geomagnetic field spans from human history and archaeology, to palaeoclimatic changes and engineering, to geomagnetic field modelling and unravelling of the geomagnetic field characteristics and ...
