Abstract:
This dataset contains airborne radar data acquired using the AWI EMR system during the Antarctic season of 2008/09. The profiles connect the EDML ice core site with South Pole. The data are available as netCDF files (including waveforms and metadata), KML files of the profile line locations, and quicklook images of the radargrams.
