Figure 14From: 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 latitudesCorrelation between the amplitudes and the E-layer ionospheric conductivity with regard to local time. A typical example of the dependence on local time of averaged amplitudes and two-dimensional height-integrated ionospheric conductivities from an altitude of 90 to 150 km.Back to article page
