Local gravity network as a reference station for the IGRF

, 2019
The newly created International Gravity Reference Frame (IGRF) will heavily rely on widely distributed reference stations. It is required that at any time of the year the instantaneous value of gravity will be available at such reference stations.

A candidate secular variation model for IGRF-13 based on MHD dynamo simulation and 4DEnVar data assimilation [PDF]

Earth, Planets and Space, 2020
We have submitted a secular variation (SV) candidate model for the thirteenth generation of International Geomagnetic Reference Field model (IGRF-13) using a data assimilation scheme and a magnetohydrodynamic (MHD) dynamo simulation code.

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
