Abstract:
This dataset contains airborne radar data acquired using the AWI ultra-wideband microwave radar (UWBM) during the Arctic season of 2016. The profiles extend across the Greenland Ice Sheet over 79°N Glacier (Nioghalvfjerdsbræ; northeast Greenland), Hiawatha Glacier (northwest Greenland) and Jakobshavn Isbræ (southwest Greenland). The data are available as netCDF files (including waveforms and metadata), KML files of the profile line locations, and quicklook images of the radargrams. For every profile we provide four radar products (img_01, img_02, img_03, img_04), which correspond to the four polarizations (VV, VH, HH, HV).
