abstract = "{With the warming of the global climate, the mass loss of the Greenland
ice sheet is intensifying, having a profound impact on the
rising of the global sea level. Here, we used Gravity Recovery
and Climate Experiment (GRACE) RL06 data to retrieve the time
series variations of ice sheet mass in Greenland from January
2003 to December 2015. Meanwhile, the spatial changes of ice
sheet mass and its relationship with land surface temperature
are studied by means of Theil-Sen median trend analysis, the
Mann-Kendall (MK) test, empirical orthogonal function (EOF)
analysis, and wavelet transform analysis. The results showed:
(1) in terms of time, we found that the total mass of ice sheet
decreases steadily at a speed of -195 {\ensuremath{\pm}} 21
Gt/yr and an acceleration of -11 {\ensuremath{\pm}} 2
Gt/yr$^{2}$ from 2003 to 2015. This mass loss was relatively
stable in the two years after 2012, and then continued a
decreasing trend; (2) in terms of space, the mass loss areas of
the Greenland ice sheet mainly concentrates in the southeastern,
southwestern, and northwestern regions, and the southeastern
region mass losses have a maximum rate of more than 27 cm/yr
(equivalent water height), while the northeastern region show a
minimum rate of less than 3 cm/yr, showing significant changes
as a whole. In addition, using spatial distribution and the time
coefficients of the first two models obtained by EOF
decomposition, ice sheet quality in the southeastern and
northwestern regions of Greenland show different significant
changes in different periods from 2003 to 2015, while the other
regions showed relatively stable changes; (3) in terms of
driving factors temperature, there is an anti-phase relationship
between ice sheet mass change and land surface temperature by
the mean XWT-based semblance value of -0.34 in a significant
oscillation period variation of 12 months. Meanwhile, XWT-based
semblance values have the largest relative change in 2005 and
2012, and the smallest relative change in 2009 and 2010,
indicating that the influence of land surface temperature on ice
sheet mass significantly varies in different years.}",
