From: 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 latitudes

Figure 7

Dependence on dip angle of the averaged period and PSD corresponding to spectral peak of zonal component. Standard errors of the period are around 0.1 s. The PSD is estimated by the maximum entropy method (MEM) for each 60-s data interval. The data for LT11-12 from 2001 to 2010 are used.
