Fig. 6From: Midlatitude sporadic-E episodes viewed by L-band split-spectrum InSARUnwrapped differential interferogram with a the new higher frequency and b the new lower frequency. The bandwidth is reduced to 11.9 MHz from the original 79 MHz for the ALOS2/PALSAR2 strip map high-resolution (SM1) mode. Details of the InSAR data are shown in Table 1 Back to article page
