mass balance from GRACE

[1] We use 22 monthly GRACE (Gravity Recovery and Climate Experiment) gravity fields to estimate the linear trend in Greenland ice mass during 2002 -2004. We recover a decrease in total ice mass of 82 ± 28 km 3 of ice per year, consistent with estimates from other techniques. Our uncertainty estimat...
