Abstract:
This dataset contains airborne radar data acquired using the AWIs multi-channel ultra-wideband radar system (AWI UWB) during the Arctic season of 2016. The profiles extend across the Northeast Greenland Ice Sheet at the 79°N Glacier (Nioghalvfjerdsbræ). 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)
range: Range between sensor and surface in meters
spacing: Along-track trace to trace spacing in meters
surface: Surface elevation derived from radar (WGS84) in meters
surface_pick: Picked surface reflection in two-way travel time in seconds
time: Seconds of day
twt: Two-way travel time (twt) in seconds
