Short summary
This study examines the radar characteristics of the basal unit along Dome A’s southern flank. Through manual mapping and delay-Doppler analysis, we identifies two basal unit types and maps the spatial variation of incoherent scattering. The results suggest that basal unit radar appearance is influenced by englacial temperature variability and potentially by subglacial geological controls.
