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

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

Abstract 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. This is the first contribution to the IGRF community...
