We estimate the mass balance of eight drainage basins in West Antarctica from the Gravity Recovery and Climate Experiment (GRACE) data (GFZ RL04, GSM Level 2) using a constrained inverse-gravimetric approach. We consider InSAR observations of ice-surface velocity as an indication of mass change, ass...
