Abstract

This dataset was prepared for a groundwater study centered in the California's Central Valley (CV). We estimate long-term groundwater storage loss in the CV with a novel data imputation method that uses in situ data combined with globally available Earth Observations - the Palmer Drought Severity Index (PDSI), and the Global Land Data Assimilation System (GLDAS) - to generate temporally- and spatially-interpolated groundwater elevations which we combine with storage coefficient maps to produce computed volume changes over time for the valley. We compare our results to groundwater storage changes we calculated using Gravity Recovery and Climate Experiment (GRACE) mission data and show that the two storage estimates are significantly correlated.
