abstract = "{The solid Earth deforms elastically in response to variations of surface
atmosphere, hydrology, and ice/glacier mass loads. Continuous
geodetic observations by Global Positioning System (CGPS)
stations and Gravity Recovery and Climate Experiment (GRACE)
record such deformations to estimate seasonal and secular mass
changes. In this paper, we present the seasonal variation of the
surface mass changes and the crustal vertical deformation in the
South China Block (SCB) identified by GPS and GRACE observations
with records spanning from 1999 to 2016. We used 33 CGPS
stations to construct a time series of coordinate changes, which
are decomposed by empirical orthogonal functions (EOFs) in SCB.
The average weighted root-mean-square (WRMS) reduction is 38\%
when we subtract GRACE-modeled vertical displacements from GPS
time series. The first common mode shows clear seasonal changes,
indicating seasonal surface mass re-distribution in and around
the South China Block. The correlation between GRACE and GPS
time series is analyzed which provides a reference for further
improvement of the seasonal variation of CGPS time series. The
results of the GRACE observations inversion are the surface
deformations caused by the surface mass change load at a rate of
about -0.4 to -0.8 mm/year, which is used to improve the long-
term trend of non-tectonic loads of the GPS vertical velocity
field to further explain the crustal tectonic movement in the
SCB and surroundings.}",
