This dataset contains airborne radar data acquired using the AWI EMR system (Nixdorf et al., 1999) during the Arctic season of 1996. The profiles extend in a grid around the NorthGRIP ice core site in central 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.

Project PI: Daniel Steinhage (AWI)Contact persons for AWI Radio-echo sounding data: Daniel Steinhage (daniel.steinhage@awi.de), Veit Helm (veit.helm@awi.de), Olaf Eisen (olaf.eisen@awi.de)--The data are available as netCDF files, KML files, and quicklook images (JPEGs) of the radargrams.--The netCDF files contain the following variables:altitude: Platform altitude (WGS84) in metersbed_elevation: bed elevation for each trace (using no firn correction and permitivity of ice: 3.15) in metersbed_pick: picked bed location for each trace, expressed as twt in secondsdata: radar datadata_agc: scaled radar data using automatic gain control (AGC)distance: Along-track distance in metersice_thickness: ice thickness for each trace (using no firn correction and permitivity of ice: 3.15) in meterslat: Latitude in decimal degreeslon: Longitude in decimal degreesrange: Range between sensor and surface in metersspacing: along track trace to trace spacing in meterssurface: surface elevation derived from radar (WGS84) in meterssurface_pick: picked surface reflection in two-way travel time in secondstime: Seconds of daytwt: Two-way travel time (twt) in seconds--The KML files are in EPSG:4326, and the quicklook images show the AGC product of the radargram.
