Geomagnetic ground survey in Slovakia for the 2007.5 epoch

Contributions to Geophysics and Geodesy, 2009
New  geomagnetic ground  survey  was  carried  out in  years  2006–2008.   The survey  was accomplished under  fair geomagnetic-activity conditions during  the minimum phase  of a solar  activity  cycle No. 23.  The  measurements  of the geomagnetic field

Assessing the Economic Benefits of Space Weather Mitigation Investment Decisions: Evidence From Aotearoa New Zealand

Space Weather, Volume 24, Issue 10, October 2026.
Abstract Space weather events pose a growing threat to modern economies, yet their macroeconomic consequences remain underexplored. This study presents the first dedicated economic assessment of geomagnetic storm impacts on Aotearoa New Zealand, quantifying potential gross domestic product (GDP) losses across seven conservative disruption and ...

Strategies for Mitigating the Impact of Ionospheric and Tropospheric Delay on Sentinel‐1 Interferograms in Northwestern Argentina

Earth and Space Science, Volume 13, Issue 10, October 2026.
Abstract This study investigates the impact and mitigation of ionospheric and tropospheric delays on Sentinel‐1 interferograms in northwestern Argentina. The research focuses on the Santa María Basin in the south‐central Andes, a region characterized by moderate seismic deformation, monsoonal moisture supply, a steep east‐west rainfall gradient, and ...

Schumann Resonance Frequency Increase Following Recurrent Solar Wind Stream Onsets

Earth and Space Science, Volume 13, Issue 10, October 2026.
Abstract Recurrent high‐speed streams and corotating interaction regions (HSS/CIRs) are common solar‐wind drivers, but their influence on Schumann resonance (SR) frequencies remains poorly quantified. We analyzed 173 threshold‐defined HSS/CIR proxy onsets using superposed epoch composites, bootstrap uncertainty, and a month‐matched random‐epoch null ...

Geomagnetic field variations in the past: an introduction

, 2020
In the last decades, palaeomagnetic research has provided us with a picture of the temporal and spatial behaviour of the Earth’s magnetic field (EMF) from its origin up to the present day.

Global Implications of Terrain‐Induced Bias in Paleomagnetic Data From 3D Forward Modeling of Mt. Etna

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract In paleomagnetism, records of paleosecular variation (PSV) on centennial timescales are often based on magnetic measurements from lava flows. However, samples from recent flows that cooled in known magnetic fields often fail to produce the expected paleomagnetic directions, and samples from the same flow often show large within‐ and between ...

The Size of Greater India: Estimates by Comparing the Apparent Polar Wander Paths of the Tethyan Himalaya and the Indian Craton

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.
Abstract The northern extent of Greater India is a critical, yet highly debated, parameter for reconstructing the India‐Asia collision. Previous paleomagnetic estimates, including the fill‐the‐gap and fixed great circle approaches, yield widely varying results, spanning from ∼200 to ∼3,000 km. These large discrepancies stem principally from two primary

Equatorial F‐Region Responses to the Main Phase of the 10 May 2024 Geomagnetic Storm Over the South American Sector: Observations and Model Simulations

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract This study examines the equatorial ionospheric response over the South American sector during the onset of the extreme 2024 Mother's Day geomagnetic storm, which began at ∼17 UT on 10 May and reached the G5 level. Pronounced disturbances in ionospheric electrodynamics were observed under both daytime and nighttime conditions. Variations in the

Coordinate Systems and Transforms in Space Physics: Terms, Definitions, Implementations, and Recommendations for Reproducibility

Journal of Geophysical Research: Space Physics, Volume 131, Issue 10, October 2026.
Abstract In space physics, acronyms for coordinate systems (e.g., GEI, GSM) are commonly used; however, differences in their definitions and implementations can prevent reproducibility. In this work, we compare definitions in online resources, software packages, and frequently cited journal articles and show that implementation differences can lead to ...
