Fig. 5.From: Propagation of large amplitude ionospheric disturbances with velocity dispersion observed by the SuperDARN Hokkaido radar after the 2011 off the Pacific coast of Tohoku EarthquakeSequential images of a 2-dimensional distribution of the line-of-sight velocities of the GS-scatter echoes observed by the SuperDARN Hokkaido radar. The wavefronts of the traveling disturbances at 0600:12 UT, scan (b) are illustrated by broken lines. The hatched regions are affected by 2-hop echoes, and are excluded from the analysis.Back to article page
