Present day regional mass loss of Greenland observed with satellite gravimetry

EJO. Schrama, B. Wouters, B. Vermeersen.

This paper summarizes results obtained for Greenland’s mass balance observed with NASA’s GRACE mission. We estimate a Greenland ice sheet mass loss t −201 ± 19 Gt/yr including a discernible acceleration of −8 ± 7 Gt/yr2 between March 2003 nd February 2010. The mass loss of glacier systems on the southeast of reenland has slowed down while the mass loss increases toward the north along the west side of Greenland. The mass balance can be compared with results obtained by regional climate model of the Greenland system and ice sheet altimeter data obtained from NASA’s ICEsat mission. Our GRACE-only results differ to within 15% to these independently calculated values, we will comment on the possible causes and the quality of the glacial isostatic adjustment model which is used to correct geodetic datasets.
