Fig. 3

Current systems for \(B_z < -1\) nT, Northern Hemisphere in darkness and Southern Hemisphere in sunlight. The format and scales are the same as in Fig. 1. The sunlit/dark conditions were imposed by requiring that the sunlight terminator must cross the noon meridian equatorward of \(80^\circ\) (marked by a black bar and a sunward pointing arrow in the Northern Hemisphere vertical current plot). This was fulfilled for approximately \(1.5\times 10^6\) measurements
