Mass balance of the Greenland ice sheet from 1958 to 2007
We combine estimates of the surface mass balance, SMB, of the Greenland ice sheet for years 1958 to 2007 with measurements of the temporal variability in ice discharge, D, to deduce the total ice sheet mass balance. During that time period, we find a robust correlation (R2= 0.83) between anomalies i...
