Modeling of regional magnetic field applying spherical functions: theoretical aspect

open access: yesГеофизический журнал, 2019
Observation of geomagnetic field, measurement of its components values and establishment on their base models of geomagnetic field as well as geomagnetic mapping are the main trend of geomagnetic studies.

The International Geomagnetic Reference Field [PDF]

open access: yes, 2011
The International Geomagnetic Reference Field (IGRF) is an internationally agreed and widely used mathematical model of the Earth’s magnetic field of internal origin. We describe its inception in the 1960s and how it has developed since. We also describe

Measurement of geomagnetic field at sea during JARE-30, 1988-1989

open access: yesAntarctic Record, 1990
Three components and total intensity of the geomagnetic field were measured by STCM (Shipboard Three Components Magnetometer) and a proton magentometer at the same time at sea during the 30th Japanese Antarctic Research Expedition.

Wavelet analysis of geomagnetic jerks [PDF]

open access: yes, 2013
Geomagnetic jerks, or secular variation impulses, are abrupt changes in the slope of the first time derivative of the Earth's magnetic field. These changes occur on time scales of the order of a year. It has been demonstrated that the jerks might be more

Error model of geomagnetic-field measurement and extended Kalman-filter based compensation method. [PDF]

open access: yesPLoS 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 ...

Continuous underground observation of the geomagnetic field in Xuzhou City, North China, and its time-varying characteristics

open access: yesFrontiers in Earth Science
Underground space in Xuzhou City, North China, has become a favorable site for continuous geomagnetic observation to reveal geomagnetic-field variations and to monitor seismic activity due to its distinct advantage of an “ultra-quiet” and “ultra-clean ...

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

open access: yesAnnales 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 ...

The Geomagnetic Field

open access: yesJournal of High Energy Physics, Gravitation and Cosmology, 2016
In this paper a solution to the problem of the self-generated magnetic field of the Earth is pro-posed. The solution is based on the existence of a steady-state current distribution localized in some region inside the convective zone of the planet, constituted by the fluid Outer Core.
