Comparisons between satellite images and time-averaged radar images. (a) Satellite image: ALOS (24 July, 2008, 10:37) and time-averaged radar image (24 July, 2008, 11:00–11:17), (b) satellite image: GeoEye (21 November, 2009, 10:47) and time-averaged radar images (21 November, 2009). The ring-shaped features which appear in the time-averaged images of the lower panels are due to some interference in the radar observation; however, its cause is not known.
