Description

This data set presents the gridded radiostratigraphy of the Greenland Ice Sheet using very high frequency (VHF) radar sounding data, collected by The Center for Remote Sensing and Integrated Systems (CReSIS) at The University of Kansas.

Version Description

-Added data from six airborne campaigns (2014–2019) -Improved quality control and accelerated reflection tracing and matching by including an automatic test for stratigraphic conformability, a thickness-normalized reprojection for radargrams, and automatic inter-segment reflection matching -Reviewed and augmented the 1993–2013 radiostratigraphy and applied an existing independently developed method for predicting radiostratigraphy to the previously untraced campaigns (2014–2019) to accelerate their semi-automatic tracing
