Greenland Ice-Mass Change

Mass changes of the Greenland Ice Sheets observed by GRACE/GRACE-FO are provided in terms of two different versions: basin-averaged and gridded mass change products. Although different algorithms are used for the generation, both data sets agree within the monthly GRACE uncertainty at basin level. Both products are corrected for Glacial Isostatic Adjustment (GIA) based on the ICE-5G / VM2 model (click here for more details ).

The following products are available:

Basin-averaged ice-mass changes
Time series of storage variations in gigatons (Gt) for 7 major drainage basins of the Greenland Ice Sheet, including empirical uncertainty estimates.

Gridded ice-mass changes
Time series of gridded ice-mass change per surface area (kg/m²) with a formal spatial resolution of 50km x 50km.

Further information on the applied processing schemes and data products is available here as technical note.

The Level-3 ice-mass change products for Greenland are available here.
