Global lithospheric magnetic field modelling by successive regional analysis [PDF]
Earth, Planets and Space, 2006 AbstractPresent lithospheric field models, like the MF4 and CM4, are produced by least squares estimation using spherical harmonic basis functions with global support. Accounting for the different properties of magnetic data at low and high latitudes, a method that can take regional differences into account is proposed.

Spatiospectral concentration of vector fields on a sphere [PDF]
, 2013 We construct spherical vector bases that are bandlimited and spatially concentrated, or, alternatively, spacelimited and spectrally concentrated, suitable for the analysis and representation of real-valued vector fields on the surface of the unit sphere,

Geopotential field anomalies and regional tectonic features – two case studies: southern Africa and Germany [PDF]
Solid Earth, 2016 Maps of magnetic and gravity field anomalies provide information about physical properties of the Earth's crust and upper mantle, helpful in understanding geological conditions and tectonic structures.

Magnetic Structure and its Tectonic Implication Around Longmenshan Fault Zone Revealed by EMAG2v3
Frontiers in Earth Science, 2022 The formation of magnetic minerals is bound up with the tectonic evolution history, whereupon the distribution of magnetic anomalies has great meanings for regional tectonics.

Insolation driven variations of Mercury’s lithospheric strength [PDF]
, 2010 Mercury's coupled 3:2 spin-orbit resonance in conjunction with its relatively high eccentricity of ~0.2 and near-zero obliquity results in both a latitudinal and longitudinal variation in annual average solar insolation and thus equatorial hot and cold ...

A Swarm lithospheric magnetic field model to SH degree 80 [PDF]
Earth, Planets and Space, 2016 The Swarm constellation of satellites was launched in November 2013 and since then has delivered high-quality scalar and vector magnetic field measurements. A consortium of several research institutions was selected by the European Space Agency to provide a number of scientific products to be made available to the scientific community on a regular ...

2021年5月22日玛多MS7.4地震震前岩石圈磁场变化特征分析
Dizhen xuebao, 2021 本文利用2019年和2020年两期的全国流动地磁矢量数据，针对玛多MS7.4地震震中附近的岩石圈磁场空间分布，分析研究了岩石圈磁场各个分量的震前变化特征。结果表明，玛多MS7.4地震发生前，震中附近的岩石圈磁场分量均发生了不同程度的变化：震中位于各分量的弱变化区域和零变线附近；震中位于各分量的高梯度带和低梯度带之间。本文证实了地震发生前会引起岩石圈磁场变化这一现象，并总结了震前地磁分量的变化特征，为今后强地震（尤其是M≥7.0地震）的震磁关系研究提供了一个震例参考。
