AMPERE and SuperMAG currents. AMPERE (left) radial currents and SuperMAG (right) equivalent currents in the Northern hemisphere for periods when IMF \(B_z < -2\) nT. The format and scales are the same as in Fig. 1, except that AMPERE uses altitude-adjusted corrected geomagnetic (AACGM) coordinates, which is very similar to modified apex coordinates at high latitudes (e.g., Laundal and Gjerloev 2014)
