The Induced Magnetic Field of an Equatorial Conductivity Anomaly in Europa's Ocean: Surface Field Maps

This archive contains results for the publication "The Induced Magnetic Field of an Equatorial Conductivity Anomaly in Europa’s Ocean", Rogan et al., 2026. The results model the induced mangetic field response of a set of Europan ocean models with anomalous equatorial conductivity regions. The response is modelled for each inducing field direction of the IAU boyd-fixed coordinate system, centred on Europa. The induced magnetic fields were modelled with GoFEM through the pyGoFEM python frontend (https://github.com/GoFEM/pyGoFEM, Grayver A.V., 2015, Parallel 3D magnetotelluric inversion using adaptive finite-element method. Part I: theory and synthetic study, Geophysical Journal International, 202(1), pp. 584-603, doi: 10.1093/gji/ggv165) See readme.txt for an explanation of the organisation of the archive, and the accompanying paper for details of the ocean model setup and rationale.
