Magnetic Field Data Correction in Space for Modelling the Lithospheric Magnetic Field
Space Science Reviews, 2016The Earth’s magnetic field as it is measured by low-Earth orbit satellites such as Swarm and CHAMP results from the superposition of internal and external source fields overlapping in time and in space. The Earth’s lithospheric field is one of the weakest sources detectable from space and its accurate description requires treatments of rapidly-varying ...

A high resolution lithospheric magnetic field model over China
Science China Earth Sciences, 2013CHAMP satellite data and ground-based magnetic observations are used and combined to map the lithospheric magnetic field over China by means of the revised spherical cap harmonic analysis (R-SHCA) modeling technique. The magnetic field is described to a spatial resolution of 150 km at the mean Earth’s radius, which represents a good compromise between ...

Mapping and Interpretation of the Lithospheric Magnetic Field
2010We review some of the controversial and exciting interpretations of the magnetic field of the earth’s lithosphere occurring in the four year period ending with the IAGA meeting in Sopron in 2009. This period corresponds to the end of the Decade of Geopotential Research, an international effort to promote and coordinate a continuous monitoring of ...

Computers & Geosciences, 2016
A newly developed software package to calculate the magnetic field in a spherical coordinate system near the Earth's surface and on satellite height is shown to produce reliable modeling results for global and regional applications. The discretization cells of the model are uniformly magnetized spherical prisms, so called tesseroids.

Lithospheric drift on early Mars: Evidence in the magnetic field
Icarus, 2010Abstract The crustal magnetic anomalies on Mars may represent hot spot tracks resulting from lithospheric drift on ancient Mars. As evidence, an analysis of lineation patterns derived from the ΔBr magnetic map is presented. The ΔBr map, largely free of external magnetic field effects, allows excellent detail of the magnetic anomaly pattern ...

A lithospheric magnetic field model to spherical harmonic degree 13
2023Detailed mapping of the Earth's magnetic field brings key constraints on the composition, dynamics, and history of the crust. Satellite and near-surface measurements detect different length scales and are complementary. However, direct global inversion of a design matrix built with magnetic field measurements locations of near surface and satellite ...

Physics of the Earth and Planetary InteriorsDetailed mapping of Earth’s lithospheric magnetic field provides important insights into the composition, dynamics, and geological history of the crust. This field can be modeled using satellite and near-surface magnetic measurements. However, structures larger than approximately 2500 km in scale are obscured by the dominant magnetic signal generated ...

Mapping the Lithospheric Magnetic Field from CHAMP Scalar and Vector Magnetic Data
2003Eighteen months into the CHAMP mission there is now a seizable data set of scalar and vector magnetic measurements. With this data the lithospheric magnetic field can be mapped far more accurately than in previous missions.
