Repeat station data compared to a global geomagnetic field model

Annals of Geophysics, 2013
Geomagnetic repeat station surveys with local variometers for improved data reductions have been carried out in Germany for about ten years. For nearly the same time interval the satellites Ørsted and CHAMP have provided a good magnetic field data ...

长宁地区岩石圈磁场磁偶极子反演研究

Dizhen xuebao
四川长宁地区平均点距间隔2 km的952个测点测得的岩石圈磁场空间分布结果显示，长宁背斜内东西部存在显著的磁场分布差异，且该差异可能与地震活动区域相关，例如：背斜内部对应岩石圈磁场正值区域，背斜边界对应负值区域；背斜的西北边界区域对应最显著的岩石圈磁场负值，背斜东北侧以岩石圈磁场正值分布为主，背斜南侧以岩石圈磁场负值为主。基于上述岩石圈磁场数据，我们构建了区域磁偶极子反演的技术途径以开展磁偶极子源的反演研究。具体途径为：将化极后的长宁背斜岩石圈磁场进行快速傅里叶变换 ...

Advancements in low Earth orbit satellite magnetic field measurements and global geomagnetic field modeling

地球与行星物理论评
Low Earth orbit (LEO) satellites have emerged as a primary tool for global geomagnetic field detection and model refinement, owing to their wide coverage, high resolution, and absence of geographical limitations.

Co-estimation of core and lithospheric magnetic fields by a maximum entropy method

Geophysical Journal International
SUMMARY Satellite observations of the geomagnetic field contain signals generated in Earth’s interior by electrical currents in the core and by magnetized rocks in the lithosphere. At short wavelengths the lithospheric signal dominates, obscuring the signal from the core. Here we present details of a method to co-estimate separate models

Regarding the article by V.V. Gordienko «On the nature of the Earth’s magnetic field»

Геофизический журнал
V.V. Gordienko's article "On the Nature of the Earth's Magnetic Field" is aimed at criticizing plate tectonics. The author argues that paleomagnetic data are used to justify the mechanisms of lithospheric plate movement without sufficient grounds ...
