Fig. 11From: On using a double-thin-shell approach and TEC perturbation component to sound night-time mid-latitude E–F couplingTime variation of TECPs at E- (top) and F-shell heights (bottom) on 11 June 2007 (DOY 162), along the line from northeast to southwest indicated as the red dashed line in Fig. 1. The black and gray dashed lines represent the occurrence time of perturbations and the alignment of evident downward-sloping stripes, respectivelyBack to article page
