This dataset includes Ground Penetrating Radar (GPR) and GPS position data from the 2011 traverse from Thule to Summit, Greenland, as reported in Hawley et al. 2014. We have concatenated the GPR data from the raw files, and collocated the GPS measurements, to generate a series of GPR and GPS measurements with high location accuracy. The GPR data clearly show isochronous layers in the upper 30 meters of the firn, and were used in the above-mentioned paper to generate accumulation estimates.
