The Likely Basal Thermal State of the Greenland Ice Sheet data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated to Version 2. This data set provides a revised synthesis mask of the likely basal thermal state of the Greenland Ice Sheet based on borehole data, thermomechanical ice-flow models, bed topography, a multi-year surface velocity mosaic, and airborne radar soundings. The temporal coverage for this data set spans 23 June 1993 to 20 May 2017.
