Candidate geomagnetic field models for IGRF-14 and secular acceleration since 2020
Earth, Planets and SpaceIGRF-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 ...

Report of the panel on earth structure and dynamics, section 6 [PDF]
The panel identified problems related to the dynamics of the core and mantle that should be addressed by NASA programs. They include investigating the geodynamo based on observations of the Earth's magnetic field, determining the rheology of the mantle ...

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.

Statistical forecasting techniques applied to observatory data for core field modelling [PDF]
, 2017 Modelling of the geomagnetic field is a complex challenge, hindered by noisy and incomplete ground and satellite observations, and the extent to which we can separate the contributions of the various field sources in these data.

The Earth's figure axis determined from the polar motion data [PDF]
, 2012 The polar motion data is analyzed to obtain accurate position of the figure axis referred to the Earth-fixed frame. The variation of the figure axis should be the basic object to which the geophysical events are linked.
