Investigation of MAGSAT and TRIAD magnetometer data to provide corrective information on high-latitude external fields [PDF]
The compilation of a catalog of the MAGSAT-observed high altitude disturbances is discussed and an example of contents and format is given. The graphs allow the investigation of Birkeland current signatures which are superimposed upon the main ...

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract At frequently erupting volcanoes, magma and volatiles ascend through established pathways, but the complete picture of their branching and supply system remains unclear. We integrated self‐potential (SP), broadband magnetotelluric (MT), and helium isotope observations to image magma and volatile pathways beneath Sakurajima Volcano.

Geomagnetic field variability: geomagnetic dynamo and helical distributed chaos
, 2020 It is shown that helicity dynamics dominates the thermal convection-driven geomagnetic field variability. The notion of the distributed chaos has been used for this purpose. The large-scale circulation in the Earth's outer (metallic liquid) core is especially sensitive to the helicity dynamics and its chaotic reversals can be associated with the ...

A study of geomagnetic storms [PDF]
Twenty-one geomagnetic storm events during 1966 and 1970 were studied by using simultaneous interplanetary magnetic field and plasma parameters. Explorer 33 and 35 field and plasma data were analyzed on large-scale (hourly) and small-scale (3 min ...

Magnetic Signatures of a Plasma Wake Behind the Swarm Satellites
Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract This study provides first observational evidence of a plasma wake behind ESA's Swarm satellites, manifesting itself by a brief magnetic field strength spike and bipolar field variations in transverse direction. These magnetic signatures occur only near the dip‐equator where the magnetic declination is close to zero.

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.Abstract The oceanic tidal magnetic field, mainly driven by the circular orbital motion of the Moon, is an essential part of the time‐varying geomagnetic field. The previously adopted time‐harmonic (TH) base worked well in fitting the primary M2 ${M}_{2}$ tidal field, but extracting the other weaker modes like the N2 ${N}_{2}$ was difficult with only a
