Basal conditions of the onset zone of the Northeast Greenland Ice Stream derived from airborne ultra-wideband radar data

We evaluate basal roughness and basal return echoes as well as hydraulic pathways in the context of the current ice stream geometry and ice surface velocity. The data comprises three individual datasets: 1) Spectral subglacial bed roughness data 2) Bed return power (BRP) and waveform abruptness data 3) Hydropotential and subglacial water routing data (geotiff and nc files) Email address of the provider: steven.franke@awi.de, daniela.jansen@awi.de, olaf.eisen@awi.de
