A global lithospheric magnetic field model between ± 65° latitude derived from CSES satellite scalar data

open access: yesPhysics of the Earth and Planetary Interiors, 2023
The China Seismo-Electromagnetic Satellite (CSES) was launched successfully in February 2018. It is China's first satellite to measure geophysical fields with scientific goals in both space and solid earth physics.

A high resolution lithospheric magnetic field model over China

Science China Earth Sciences, 2013
CHAMP 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 ...

Magnetic Field Data Correction in Space for Modelling the Lithospheric Magnetic Field

Space Science Reviews, 2016
The 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 lithospheric magnetic field model to spherical harmonic degree 13

2023
Detailed 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 ...

Forward modeling magnetic fields of induced and remanent magnetization in the lithosphere using tesseroids

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.

A Comparison of Global Lithospheric Field Models Derived from Satellite Magnetic Data

2003
Satellite missions over more than three decades, have added immensely to our understanding of the geomagnetic field. Here, we give a comparison of the lithospheric field models, prepared by various workers from POGO, Magsat, Orsted and CHAMP satellite data.
