This dataset contains airborne radar data acquired using the AWI Accumulation Radar (ACCU) system during the Antarctic season of 2013/14. The profiles cover wester DML, Sörasen, Recovery Glacier and Antarctic Peninsula. The data are available as netCDF files (including waveforms and metadata), KML files of the profile line locations, and quicklook images of the radargrams.
