A New Four‐Component L*‐Dependent Model for Radial Diffusion Based on Solar Wind and Magnetospheric Drivers of ULF Waves

open access: yesSpace Weather, 2023
Waves which couple to energetic electrons are particularly important in space weather, as they drive rapid changes in the topology and intensity of Earth's outer radiation belt during geomagnetic storms. This includes Ultra Low Frequency (ULF) waves that

Characterisation of the electromagnetic component in ultra-high energy inclined air showers [PDF]

open access: yes, 2009
Inclined air showers - those arriving at ground with zenith angle with respect to the vertical theta > 60 deg - are characterised by the dominance of the muonic component at ground which is accompanied by an electromagnetic halo produced mainly by muon ...

Testing Geomagnetic Reference Field models for 1990-2000 with data from the Trelew Geomagnetic Observatory, Argentina [PDF]

open access: yesGeofísica Internacional, 2003
Every five years a new International Geomagnetic Reference Field (IGRF) model is released and the secular variation for the previous period is updated, producing the definitive DGRF model.

Simulation of Atmospheric Muon and Neutrino Fluxes with CORSIKA

open access: yes, 2003
The fluxes of atmospheric muons and neutrinos are calculated by a three dimensional Monte Carlo simulation with the air shower code CORSIKA using the hadronic interaction models DPMJET, VENUS, GHEISHA, and UrQMD.

Correlation‐based modeling and separation of geomagnetic field components [PDF]

open access: yesJournal of Geophysical Research: Solid Earth, 2016
AbstractWe introduce a technique for the modeling and separation of geomagnetic field components that is based on an analysis of their correlation structures alone. The inversion is based on a Bayesian formulation, which allows the computation of uncertainties.

Geomagnetic effects on cosmic ray propagation under different conditions for Buenos Aires and Marambio, Argentina [PDF]

open access: yes, 2014
The geomagnetic field (Bgeo) sets a lower cutoff rigidity (Rc) to the entry of cosmic particles to Earth which depends on the geomagnetic activity. From numerical simulations of the trajectory of a proton using different models for Bgeo (performed with ...

Short-Term Magnetic Field Variations From the Post-depositional Remanence of Lake Sediments

open access: yesFrontiers in Earth Science, 2018
Paleomagnetic records obtained from lake sediments provide important constraints on geomagnetic field behavior. Secular variation recorded in sediments is used in global geomagnetic field models, particularly over longer timescales when archeomagnetic ...
