The US Geological Survey, John Wesley Powell Center for Analysis and Synthesis, is offering a funding opportunity to integrate GRACE satellite and ground-based estimates of groundwater change in the conterminous United States. The purpose of this project is to combine ground-based techniques with GRACE data to construct a national map of groundwater depletion. Specific objectives include quantifying total water storage from different GRACE products and estimate groundwater storage and related uncertainties for five major aquifers (Central Valley, Arizona Basin and Range, High Plains, Mississippi Embayment, Columbia Plateau); quantifying groundwater storage changes using groundwater level monitoring and regional and national modeling analyses for major aquifers in the conterminous United States; and integrating GRACE and ground-based data to improve interpretation of GRACE total water storage changes to potentially improve model storage parameters in the National Groundwater Model.
