TL;DR: The 12th generation of the International Geomagnetic Reference Field (IGRF) was adopted in December 2014 by the Working Group V-MOD appointed by the International Association of Geomagnetism and Aeronomy (IAGA) as discussed by the authors.
Journal ArticleDOI
Scaling properties of convection-driven dynamos in rotating spherical shells and application to planetary magnetic fields
TL;DR: In this paper, an extensive set of dynamo models in rotating spherical shells, varying all relevant control parameters by at least two orders of magnitude, were studied and their scaling laws were established.
Journal ArticleDOI

TL;DR: In this article, the authors present the results of a benchmark study for a convection-driven magnetohydrodynamic dynamo problem in a rotating spherical shell and provide an accurate reference standard with high confidence.
Journal ArticleDOI
Thermochemical flows couple the Earth's inner core growth to mantle heterogeneity
TL;DR: It is shown that a single model of thermochemical convection and dynamo action can account for all these effects by producing a large-scale, long-term outer core flow that couples the heterogeneity of the inner core with that of the lower mantle.
Journal ArticleDOI

TL;DR: The International Geomagnetic Reference Field (IGRF) was adopted by the IGA Division V Working Group (V-MOD) in 2019 as discussed by the authors, which provides the equations defining the IGRF, the spherical harmonic coefficients for this thirteenth generation model, maps of magnetic declination, inclination, and total field intensity for the epoch 2020.0, and maps of their predicted rate of change for the 2020 to 2025.0 time period.
