Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract Equatorial plasma bubbles (EPBs) are ionospheric irregularities generated by Rayleigh–Taylor instability (RTI) that disrupt satellite communications. We quantify secular change of RTI growth rates and isolate underlying drivers using WACCM‐X simulations.

First Observation of Four‐Band Ion Cyclotron Whistlers
Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.Abstract Ion cyclotron whistlers are frequently observed in low Earth orbit, typically formed when right‐hand polarized lightning whistlers undergo polarization reversal at crossover frequencies. In this study, we for the first time report a four‐band ion cyclotron whistler event detected by Van Allen Probe A.

Wavelet analysis of geomagnetic jerks [PDF]
, 2013 Geomagnetic jerks, or secular variation impulses, are abrupt changes in the slope of the first time derivative of the Earth's magnetic field. These changes occur on time scales of the order of a year. It has been demonstrated that the jerks might be more

Геофизический журнал, 2019 To study the changes in the local variations of geomagnetic field, the Karadag point was chosen due to the fact that we found previously on increased insolation and the surface temperature of the earth at this point over the last century (compared to ...

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract The upper thermosphere is important in the context of space weather, but continuous monitoring of the thermosphere at high latitudes remains limited despite its strong variations associated with geomagnetic activity. Orthohelium, He(23S), is found from the upper thermosphere to lower exosphere, and is a promising tracer of atmospheric dynamics.

Shannon information of the geomagnetic field for the past 7000 years [PDF]
Nonlinear Processes in Geophysics, 2010 The present behaviour of the geomagnetic field as expressed by the International Geomagnetic Reference Field (IGRF) deserves special attention when compared with that shown over the past few thousands of years by two paleomagnetic/archeomagnetic models ...

Quantifying the Effects of Nickel on Earth’s Inner‐Core Nucleation
Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.Abstract The formation of Earth’s solid inner core marks a major transition in the thermal and chemical evolution of the deep Earth, yet its origin remains paradoxical, as initial nucleation appears to require unrealistically large undercooling in the outer core.

NOAA/NCEI and University of Colorado candidate models for IGRF-13
Earth, Planets and Space, 2021 The International Geomagnetic Reference Field (IGRF) is a set of parameters representing the large-scale internal part of Earth’s magnetic field. The 13th generation IGRF requested candidate models for a definitive main field for 2015.0, a provisional ...

Geochemistry, Geophysics, Geosystems, Volume 27, Issue 10, October 2026.Abstract The Aurora hydrothermal vent field (AVF) is the first confirmed active vent system on the Arctic Ocean seafloor, located at the western end of the ultraslow spreading Gakkel Ridge. It marks a distinctive endmember among ridge‐axis hydrothermal systems, where volcanic construction and ultramafic influence co‐exist.
