NASA Earthdata CMR2025 · Raster · GeoTIFF

This data set contains a bed topography and 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.

NASA Earthdata CMR2025 · Array · NetCDF

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.

NASA Earthdata CMR2022 · Array · NetCDF

The Likely Basal Thermal State of the Greenland Ice Sheet (GrIS) product contains key data sets that show how the likely basal thermal state was inferred from existing airborne and satellite data sets and recent methods, and provides a synthesis mask of the likely basal thermal state over the Greenland Ice Sheet.

NASA Earthdata CMR2019 · Array · NetCDF

This data set contains Level-3 tomographic ice thickness measurements and ice thickness errors over areas of Greenland and Antarctica. Two of the data files additionally provide bed elevation measurements. The data were derived from measurements taken by the Center for Remote Sensing of Ice Sheets (CReSIS) Multichannel Coherent Radar Depth Sounder (MCoRDS) instrument and were collected as part of
