Evaluation of influence of detrending CSES satellite data on lithospheric magnetic field modeling
Earth and Planetary PhysicsThe China Seismo-Electromagnetic Satellite (CSES) was successfully launched in February 2018. The high precision magnetometer (HPM) on board the CSES has captured high-quality magnetic data that have been used to derive a global lithospheric magnetic ...

A cubed-sphere based method for global and regional modeling of the lithospheric magnetic field
Earth and Planetary PhysicsThe Earth’s magnetic field, which has been extensively observed from ground to satellite altitudes over several decades, originates from multiple sources, such as the core dynamo, the conductive mantle, the magnetized lithosphere, and the space current ...

LCS-1: A high-resolution global model of the lithospheric magnetic field derived from CHAMP and Swarm satellite observations [PDF]
Geophysical Journal International, 2017 We derive a new model, named LCS-1, of Earth’s lithospheric field based on four years (2006 September–2010 September) of magnetic observations taken by the CHAMP satellite at altitudes lower than 350 km, as well as almost three years (2014 April–2016 ...

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links
Geophysical Monograph Series, Page 191-228., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

An equivalent source method for modelling the global lithospheric magnetic field [PDF]
Geophysical Journal International, 2015 We present a new technique for modelling the global lithospheric magnetic field at Earth’s surface based on the estimation of equivalent potential field sources. As a demonstration we show an application to magnetic field measurements made by the CHAMP satellite during the period 2009–2010 when it was at its lowest altitude and solar activity was quiet.

Retrieving lithospheric magnetisation distribution from magnetic field models [PDF]
Geophysical Journal International, 2019 Summary We investigate to which extent the radially averaged magnetisation of the lithosphere can be recovered from the information content of a spherical harmonic model of the generated magnetic field when combined with few simple hypotheses.

Fifth‐generation lithospheric magnetic field model from CHAMP satellite measurements [PDF]
Geochemistry, Geophysics, Geosystems, 2007 Six years of low‐orbit CHAMP satellite magnetic measurements have provided an exceptionally high‐quality data resource for lithospheric magnetic field modeling and interpretation. Here we describe the fifth‐generation satellite‐only magnetic field model MF5. The model extends to spherical harmonic degree 100.

A Spherical Harmonic Model of Earth's Lithospheric Magnetic Field up to Degree 1050 [PDF]
Geophysical Research Letters, 2021 AbstractDetailed 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. Here, we build a model, selecting and processing magnetic field measurements from the German CHAMP and ESA Swarm satellites ...

Use of along-track magnetic field differences in lithospheric field modelling [PDF]
Geophysical Journal International, 2014 We demonstrate that first differences of polar orbiting satellite magnetic data in the along-track direction can be used to obtain high resolution models of the lithospheric field. Along-track differences approximate the north–south magnetic field gradients for non-polar latitudes.
