A Gaussian Model for Simulated Geomagnetic Field Reversals [PDF]
Field reversals are the most spectacular changes in the geomagnetic field but remain little understood. Paleomagnetic data primarily constrain the reversal rate and provide few additional clues.

The CHAOS-4 geomagnetic field model [PDF]
We present CHAOS-4, a new version in the CHAOS model series, which aims to describe the Earth's magnetic field with high spatial and temporal resolution. Terms up to spherical degree of at least n = 85 for the lithospheric field, and up to n = 16 for the time-varying core field are robustly determined.More than 14 yr of data from the satellites Ørsted,

High-Precision Aeromagnetic Compensation Method Under the Influence of the Geomagnetic Field [PDF]
Aeromagnetic surveys play an important role in geophysical exploration and many other fields. In many applications, magnetometers are installed aboard an aircraft to survey large areas.

Geomagnetic field shielding over the last one hundred thousand years
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 ...

Regularized geomagnetic field modelling using monopoles [PDF]
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.

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

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 ...
