abstract = "{GPS is accurately recording vertical motion of Earth's surface in
elastic response to seasonal changes in surface water storage in
California. California's mountains subside up to 12 mm in the
fall and winter due to the load of snow and rain and then rise
an identical amount in the spring and summer when the snow
melts, the rain runs off, and soil moisture evaporates. We
invert the GPS observations of seasonal vertical motions to
infer changes in equivalent water thickness. GPS resolves the
distribution of change in total water across California's
physiographic provinces at a resolution of 50 km, compared to
200 km resolution from the Gravity Recovery and Climate
Experiment. The seasonal surface water thickness change is 0.6 m
in the Sierra Nevada, Klamath, and southern Cascade Mountains
and decreases sharply to about 0.1 m east into the Great Basin
and west toward the Pacific coast. GPS provides an independent
inference of change in total surface water, indicating water
storage to be on average 50\% larger than in the NLDAS-Noah
hydrology model, likely due to larger changes in snow and
reservoir water than in the model. Seismicity and land uplift
produced by groundwater loss in California's Central Valley is
also being evaluated.}",
