Fig. 7From: Temporal resolution of internal magnetic field modes from satellite data(Top) Secular variation due to translation and rotation of the eccentric dipole, for the first half of 2014 at 500 km altitude, using CHAOS-6 to compute the ED parameters. (Bottom) Secular variation computed from the IGRF-12 model (2015–2020). Both represented as \(\dot{B}_r\), \(\dot{B}_\theta\) and \(\dot{B}_\phi\) in nT/yearBack to article page
