The IceBridge BedMachine Greenland data set, accessible through the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), has been updated to Version 5. This data set contains a bed topography/bathymetry map of Greenland based on mass conservation, multi-beam data, and other techniques. It also includes surface elevation and ice thickness data, as well as an ice/ocean/land mask. The temporal coverage now spans 1 January 1993 through 31 December 2021. A GeoTIFF representing the bed topography variable is included with Version 5.
