The influence of the geomagnetic field and of the uncertainties in the primary spectrum on the development of the muon flux in the atmosphere [PDF]

, 2004
In this paper we study the sensitivity of the flux of atmospheric muons to uncertainties in the primary cosmic ray spectrum and to the treatment of the geomagnetic field in a calculation.

Modulation of the Mid‐Latitude Ionospheric Sporadic E Layer by the Northern Polar Vortex

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract The sporadic E (Es) layer is a prominent ionospheric irregularity mainly driven by vertical wind shear at mid‐latitudes. Hereby we statistically investigate for the first time Es responses to variations of the northern polar vortex (represented by NAM index) using long‐term ionosonde observations over Japan (44 years) and Australia (34 years).

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.

New Cretaceous Paleomagnetic and Geochronologic Data From the Antarctic Peninsula: Constraints on the Pre‐Opening Tectonic Evolution of the Drake Passage

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Reconstructing oroclinal orogens along the Fuegian Andes‐northern Antarctic Peninsula provides critical constraints on the pre‐opening tectonic evolution of the Drake Passage, although such efforts are limited by a lack of reliable Cretaceous paleomagnetic and geochronological data.

Uncovering the Generation Mechanism of Low‐Frequency Chorus Waves (<0.1 fce_eq ${\boldsymbol{f}}_{\mathbf{c}\mathbf{e}\mathbf{\_}\mathbf{e}\mathbf{q}}$) During Active Geomagnetic Environments

Geophysical Research Letters, Volume 53, Issue 3, 16 February 2026.
Abstract Low‐frequency chorus waves (below 0.1 fce_eq ${f}_{\text{ce}\_\text{eq}}$, where fce_eq ${f}_{\text{ce}\_\text{eq}}$ is equatorial electron gyrofrequency) can induce the depletion of relativistic electrons in Earth's radiation belts by effective pitch angle scattering, demonstrating distinct effects on radiation belt dynamics compared to ...
