Greenland mass variation since 2002
WebJul 15, 2015 · As shown in Table 1, there are several recent investigations concentrating on the long-term trend of mass variations in the GrIS using GRACE data. But the results vary within a range of more than 100 Gt/yr, depending on the GRACE data products used, the time period covered and the algorithm adopted. WebThe Greenland cryosphere is undergoing rapid changes, and these are documented by remote sensing from space. In this paper, an inversion scheme is used to derive mass changes from gravity changes observed by GRACE, and to derive the mean annual mass loss for the Greenland Ice Sheet, which is estimated to be 204 Gt/yr for the period 2002 …

WebJul 13, 2011 · We use 2002–2010 GRACE data to compute the effects of Greenland and Antarctic ice mass variations on J2 (2.0 and 1.7 × 10 −11 /year respectively). Their combined effect on the J 2 trend during the GRACE mission is 3.7 × 10 −11 /year, which agrees well with the GIA-corrected SLR J2 trend over the same time period.
