Abstract:
This dataset contains airborne radar data acquired using the AWIs multi-channel ultra-wideband radar system (AWI UWB) during the Antarctic season of 2016/17. The profiles are located near the grounding line of the Jutulstraumen Glacier in western Dronning Maud Land, East Antarctica as well as over the Halvfarryggen ice rise. The data are available as netCDF files (including waveforms and metadata), KML files of the profile line locations, and quicklook images of the radargrams.

bed_elevation: Bed elevation for each trace (without applying a firn correction and permitivity of ice: 3.15) in meters
bed_pick: picked Bed location for each trace, expressed as twt in seconds from time zero
data: Radar data (Values in dBm after DC conversion)
data_agc: Scaled radar data using automatic gain control (AGC)
distance: Along-track distance in meters
ice_thickness: Ice thickness for each trace (without applying a firn correction and permitivity of ice: 3.15) in meters
lat: Latitude in decimal degrees (WGS84)
lon: Longitude in decimal degrees (WGS84)
