Geomagnetic core field models and secular variation forecasts for the 13th International Geomagnetic Reference Field (IGRF-13) [PDF]

Earth, Planets and Space, 2020
Observations of the geomagnetic field taken at Earth’s surface and at satellite altitude are combined to construct continuous models of the geomagnetic field and its secular variation from 1957 to 2020.

IGRF-14 secular variation prediction from core surface flow acceleration [PDF]

Earth, Planets and Space
The International Geomagnetic Reference Field (IGRF) has been regularly updated since its inception in 1965. Every recent iteration contains an estimate of the geomagnetic secular variation (SV), for the intermediate years between iterations. We submit a

Using improved Swarm’s experimental absolute vector mode data to produce a candidate Definitive Geomagnetic Reference Field (DGRF) 2015.0 model

Earth, Planets and Space, 2021
We describe the way a global model of the geomagnetic field has been built using vector field data acquired by the absolute scalar magnetometers (ASM) running in vector mode on board the Alpha and Bravo satellites of the European Space Agency (ESA) Swarm

International Geomagnetic Reference Field: the thirteenth generation

Earth, Planets and Space, 2021
In December 2019, the International Association of Geomagnetism and Aeronomy (IAGA) Division V Working Group (V-MOD) adopted the thirteenth generation of the International Geomagnetic Reference Field (IGRF). This IGRF updates the previous generation with
