abstract = "{Surface vertical deformation includes the Earth's elastic response to
mass loading on or near the surface. Continuous Global
Positioning System (CGPS) stations record such deformations to
estimate seasonal and secular mass changes. We used 41 CGPS
stations to construct a time series of coordinate changes, which
are decomposed by empirical orthogonal functions (EOFs), in
northeastern Tibet. The first common mode shows clear seasonal
changes, indicating seasonal surface mass re-distribution around
northeastern Tibet. The GPS-derived result is then assessed in
terms of the mass changes observed in northeastern Tibet. The
GPS-derived common mode vertical change and the stacked Gravity
Recovery and Climate Experiment (GRACE) mass change are
consistent, suggesting that the seasonal surface mass variation
is caused by changes in the hydrological, atmospheric and non-
tidal ocean loads. The annual peak-to-peak surface mass changes
derived from GPS and GRACE results show seasonal oscillations in
mass loads, and the corresponding amplitudes are between 3 and
35 mm/year. There is an apparent gradually increasing gravity
between 0.1 and 0.9 {\ensuremath{\mu}}Gal/year in northeast
Tibet. Crustal vertical deformation is determined after
eliminating the surface load effects from GRACE, without
considering Glacial Isostatic Adjustment (GIA) contribution. It
reveals crustal uplift around northeastern Tibet from the
corrected GPS vertical velocity. The unusual uplift of the
Longmen Shan fault indicates tectonically sophisticated
processes in northeastern Tibet.}",
