This dataset contains airborne radar data acquired using the AWI EMR system (Nixdorf et al., 1999) during the Arctic season of 2013. The profiles extend across the 79 NG (Nioghalvfjerdsbræ) other selected sites in Northeast Greenland, and Southwest Greenland Ice Sheet. The data are available as netCDF files (including waveforms and metadata), KML files of the profile line locations, and quicklook images of the radargrams.
