Regional Geomagnetic Field Model for Croatia at 2009.5 [PDF]

Acta Geophysica, 2016
Geomagnetic data of north, east and vertical components at Croatian repeat stations and ground survey sites, as well as European geomagnetic observatories and repeat stations, were used to obtain a regional geomagnetic model over Croatia at 2009.5 epoch.

The Swarm Initial Field Model for the 2014 geomagnetic field [PDF]

Geophysical Research Letters, 2015
AbstractData from the first year of ESA's Swarm constellation mission are used to derive the Swarm Initial Field Model (SIFM), a new model of the Earth's magnetic field and its time variation. In addition to the conventional magnetic field observations provided by each of the three Swarm satellites, explicit advantage is taken of the constellation ...

The CHAOS-8 geomagnetic field model

Earth, Planets and Space
We present CHAOS-8, an extension of the CHAOS field model series that describes the time-dependent near-Earth geomagnetic field, valid from 1999 to 2025. It is estimated from magnetic measurements collected by multiple low-earth-orbit satellites, such as

Geomagnetic field shielding over the last one hundred thousand years

Journal of Space Weather and Space Climate, 2022
The geomagnetic field prevents energetic particles, such as galactic cosmic rays, from directly interacting with the Earth’s atmosphere. The geomagnetic field is not static but constantly changing, and over the last 100,000 years, several geomagnetic ...

Multiscale variation model and activity level estimation algorithm of the Earth's magnetic field based on wavelet packets [PDF]

Annales Geophysicae, 2018
We suggest a wavelet-based multiscale mathematical model of geomagnetic field variations. The model is particularly capable of reflecting the characteristic variation and local perturbations in the geomagnetic field during the periods of increased ...

Regional geomagnetic core field and secular variation model over the Iberian Peninsula from 2014 to 2020 based on the R-SCHA technique

Earth, Planets and Space, 2023
The Earth’s magnetic field originated in the fluid core, the so-called core field, is the dominant contribution to the geomagnetic field. Since ancient times, the core geomagnetic field has been used primarily for geographical orientation and navigation ...

Effects of the Laschamps Excursion on Geomagnetic Cutoff Rigidities

Geochemistry, Geophysics, Geosystems, 2022
Today's geomagnetic field can prevent energetic particles, including solar energetic particles and galactic cosmic rays, from directly hitting the Earth's atmosphere.
