https://www.pangaea.de/ information publisher tableDigital This dataset contains airborne radar data acquired using the AWI EMR system (Nixdorf et al., 1999) during the Arctic season of 1997. The profiles extend in a grid around the North GRIP ice core site in central Greenland and in south-west 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. completed Steinhage, Daniel
