Data from "Predicting Global Ground Geoelectric Field With Coupled Geospace and Three‐Dimensional Geomagnetic Induction Models"

Data presented in http://dx.doi.org/10.1029/2018SW001859 excluding the first and last hours which were determined to contain partially unphysical results and probably should not be used.

Each file contains the external ground magnetic field components calculated on 5x5 degree geographic grid and the results of induction modeling using 1d and 3d ground conductivity models: total ground magnetic field components, horizontal ground electric field components. Times are given in UTC.

To reproduce Figure 8 in above reference use:

import numpy
import matplotlib.pyplot
data = numpy.load('2006-12-14T22:58:00.npz') # or 2006-12-14T22_58_00.npz
matplotlib.pyplot.colorbar(
    matplotlib.pyplot.imshow(
        data['B_3D_north'],
        cmap = matplotlib.pyplot.get_cmap('bwr'),
        vmin = -800, vmax = 800,
        extent = (-180, 180, -90, 90)
    ),
    format = '%.0f', fraction = 0.02, pad = 0.03
)
matplotlib.pyplot.show()

and substitute B_3D_east, E_3D_north, etc. for the different panels.
