                         thought to cause the distortions of L-band Synthetic Aperture 
                         Radar (SAR) images, which have been observed in recent years, but 
                         the origin of the image distortion has not yet been clearly 
                         identified experimentally. We report on the first simultaneous 
                         observation of equatorial plasma bubbles (EPBs) by the 
                         ALOS-2/PALSAR-2 satellite and ground 630-nm airglow imager in 
                         northern Brazil. We observe stripe-like distortions of SAR signal 
                         power that are aligned in the direction of local magnetic field 
                         lines. The stripe-like patterns are observed in the vicinity of 
                         airglow depletion. The result shows that the observed L-band SAR 
                         stripes are caused by ionospheric scintillation due to plasma 
                         irregularities with the scale size of hundreds of meters 
                         associated with EPBs. We show that the SAR scintillation stripes 
                         are predominantly found at the location of sharp density gradients 
                         in the two-dimensional form.",
