Geomagnetic jerks characterization via spectral analysis [PDF]
Solid Earth, 2012 In this study we have applied spectral techniques to analyze geomagnetic field time-series provided by observatories, and compared the results with those obtained from analogous analyses of synthetic data estimated from models. Then, an algorithm is here

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 ...

Earth, Planets and Space, 2020 Observations of the geomagnetic field taken at Earth’s surface and at satellite altitude are combined to construct continuous models of the geomagnetic field and its secular variation from 1957 to 2020.

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 ...

Error model of geomagnetic-field measurement and extended Kalman-filter based compensation method. [PDF]
PLoS ONE, 2017 The real-time accurate measurement of the geomagnetic-field is the foundation to achieving high-precision geomagnetic navigation. The existing geomagnetic-field measurement models are essentially simplified models that cannot accurately describe the ...

Regularized geomagnetic field modelling using monopoles [PDF]
Geophysical Journal International, 1994 SUMMARY There are many techniques for modelling the geomagnetic field, any one of which may be suitable for a particular application depending on its associated modelling goals. Each method combines a choice of functions and an approach to fitting data so that, in general, it is best suited to a particular type of field modelling, e.g.

The development of a regional geomagnetic daily variation model using neural networks [PDF]
Annales Geophysicae, 2000 Global and regional geomagnetic field models give the components of the geomagnetic field as functions of position and epoch; most utilise a polynomial or Fourier series to map the input variables to the geomagnetic field values.

Geomagnetic main field modeling with DMSP [PDF]
Journal of Geophysical Research: Space Physics, 2014 AbstractThe Defense Meteorological Satellite Program (DMSP) launches and maintains a network of satellites to monitor the meteorological, oceanographic, and solar‐terrestrial physics environments. In the past decade, geomagnetic field modelers have focused much attention on magnetic measurements from missions such as CHAMP, Ørsted, and SAC‐C.

An improved geomagnetic data selection algorithm for global geomagnetic field modelling [PDF]
Geophysical Journal International, 2007 A spherical harmonic degrees 60, global internal field model is described (called BGS/G/L/0706). This model includes a degree 15 core and piecewise-linear secular variation model and is derived from quiet-time Orsted and CHAMP satellite data sampled between 2001.0 and 2005.0.
