Abstract: The eleventh generation of the International Geomagnetic Reference Field (IGRF) was adopted in December 2009 by the International Association of Geomagnetism and Aeronomy Working Group V-MOD. It updates the previous IGRF generation with a definitive main field model for epoch 2005.0, a main field model for epoch 2010.0, and a linear predictive secular variation model for 2010.0–2015.0. In this note the equations defining the IGRF model are provided along with the spherical harmonic coefficients for the eleventh generation. Maps of the magnetic declination, inclination and total intensity for epoch 2010.0 and their predicted rates of change for 2010.0–2015.0 are presented. The recent evolution of the South Atlantic Anomaly and magnetic pole positions are also examined.

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.

TL;DR: This article reviews the current status of the knowledge of core dynamics, and elaborate on the reasons which motivate geomagnetic data assimilation studies, including the prospect to propagate the current quality of data backward in time to construct dynamically consistent historical core field and flow models, and the possibility to improve the forecast of the secular variation.
