A core-surface flow model derived from magnetic data of Macau Science Satellite-1

Earth and Planetary Physics
The core-surface flow is crucial for understanding the dynamics of the Earth’s outer core and geomagnetic secular variations. Conventional core flow models often use a single set of spherical harmonic coefficients to represent the flow both inside and ...

Dynamic Mode Decomposition of the Core Surface Flow Inverted From Geomagnetic Field Models

Geophysical Research Letters
Continuous satellite measurements of the Earth's magnetic field have advanced the characterization of spatial‐temporal variations of the main field over the past two decades.

Candidate geomagnetic field models for IGRF-14 and secular acceleration since 2020

Earth, Planets and Space
IGRF-14 is the fourteenth generation of the International Geomagnetic Reference Field (IGRF), a spherical harmonic model of Earth’s main magnetic field and its secular variation, developed through international collaboration under the auspices of the ...

Comparative views of geomagnetic jerks

, 2010
New geomagnetic field models (Wardinski and Lesur, GFZ Potsdam, 2009) covering the years 1957–2006 - here the model C3FM2 - enable new comparative secular variation investigations. Combined with the method of nonharmonic downward continuation and e.g.
