Supplemental Mode Data: "A time-continuous model of the 3D ionospheric current system and associated magnetic fields in the diurnal variation band"

This dataset contains the spatial and temporal mode data used in the paper "A time-continuous model of the 3D ionospheric current system and associated magnetic fields in the diurnal variation band". A README file inside the archive contains further information. More detail on the temporal modes can be found in the paper: Egbert, G.D., Alken, P., Maute, A. and Zhang, H., 2021. Modelling diurnal variation magnetic fields due to ionospheric currents. Geophysical Journal International, 225(2), pp.1086-1109.
