Comparison of Magnetic Anomalies of Lithospheric Origin Measured by Satellite and Airborne Magnetometers over Western Canada [PDF]
Crustal magnetic anomaly data from the OGO 2, 4 and 6 (Pogo) satellites are compared with upward-continued aeromagnetic data between 50 deg -85 deg N latitude and 220 deg - 260 deg E longitude. Agreement is good both in anomaly location and in amplitude,

A multisource geomagnetic field model incorporating ocean circulation-induced magnetic field
Earth and Planetary PhysicsThe movement of global ocean circulation in the Earth’s main magnetic field generates a measurable induced magnetic field (about 2 nT at geomagnetic satellite altitudes).

A global magnetic anomaly map [PDF]
A subset of POGO satellite magnetometer data has been formed that is suitable for analysis of crustal magnetic anomalies. Using a thirteenth order field model, fit to these data, magnetic residuals have been calculated over the world to latitude limits ...

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 ...

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 ...
