A method for analyzing spatiotemporal evolution characteristics of groundwater storage anomalies
By coordinating the processing of GRACE data with multi-source hydro-climatic factors, a parallel modeling architecture was constructed. Combining the water balance formula and measured well data, the resolution limitations of GRACE data and the heterogeneity of geological regions were solved, and high-precision spatiotemporal characteristic analysis of groundwater storage anomalies was achieved.
