A high-resolution lithospheric magnetic field model of China and surroundings by using CHAMP, Swarm, CSES-1, and MSS-1 satellite magnetic measurements and aeromagnetic anomaly data

Earth and Planetary Physics
The CUG_CLMFM3D series comprises high-resolution three-dimensional lithospheric magnetic field models for China and its surroundings. The first version, CUG_CLMFM3Dv1, is a spherical cap harmonic model integrating the WDMAMv2 (World Digital Magnetic ...

Swarm SCARF Dedicated Lithospheric Field Inversion chain

, 2013
International audienceThe forthcoming Swarm satellite mission is a constellation of three satellites dedicated to the study of the geomagnetic field. The orbital characteristics of the mission, which includes a pair of satellites flying side by side, has

The CHAOS-8 geomagnetic field model

Earth, Planets and Space
We present CHAOS-8, an extension of the CHAOS field model series that describes the time-dependent near-Earth geomagnetic field, valid from 1999 to 2025. It is estimated from magnetic measurements collected by multiple low-earth-orbit satellites, such as

Pre-Earthquake Oscillating and Accelerating Patterns in the Lithosphere–Atmosphere–Ionosphere Coupling (LAIC) before the 2022 Luding (China) Ms6.8 Earthquake

Remote Sensing
The coupling processes among the lithosphere, atmosphere, and ionosphere (LAI) during the earthquake preparation phase are still an open scientific debate.

Lithospheric magnetic anomaly map of Indian subcontinent (LAMI-1) from Swarm satellite data

A preliminary lithospheric magnetic anomaly map of the Indian subcontinent (LAMI-1) was generated utilising seven years (April 2014–December 2020) of data recorded by the Swarm satellite constellation. To obtain a high-resolution lithospheric anomaly map,

Estimating the Earth's lithospheric magnetization, thickness and magnetic field for SH degrees 1 to 50

International audienceDetailed mapping of the Earth's lithospheric magnetic field provides key constraints on the composition, dynamics and history of the crust. This field can be mapped using satellite and near-surface measurements to build a model over

Discrimination of ULF signals from an underground seismogenic current

Earth, Planets and Space
A numerical model has been elaborated to calculate ULF electromagnetic fields in the ground-atmosphere–ionosphere system created by an underground horizontal current source of a finite length.

Geophysical Coupling Before Three Earthquake Doublets Around the Arabian Plate

Atmosphere
In this study, we analysed lithospheric, atmospheric, and top-side ionospheric magnetic field data six months before the three earthquake doublets occurred in the last ten years around the Arabian tectonic plate. They occurred in 2014, close to Dehloran (
