Figure 9From: Global and frequent appearance of small spatial scale field-aligned currents possibly driven by the lower atmospheric phenomena as observed by the CHAMP satellite in middle and low latitudesComparison of amplitudes of the zonal component on the dayside with regard to Kp index. The global distribution of the amplitudes shown is for the cases when the Kp index is less than 3 (left) and equal to and larger than 3 (right).Back to article page
