英文摘要	Benefiting from the tremendous advance of modern geodetic technologies, accurate measurements provide us with novel means to weigh terrestrial water storage (TWS) and shed critical light on hydroclimatic interaction mechanisms. In this study, GNSS and GRACE observations are jointly used to investigate spatiotemporal TWS fluctuations and their connections with large-scale climate patterns in the Australian mainland. A variational Bayesian principal component analysis-based inversion method is designed to handle random data missing in GNSS and long-term data gaps in GRACE. The jointly inferred TWS estimates manifest more spatial details compared to the GRACE Mascon solutions and good resistance to non-hydrological mechanisms in GNSS data. The joint inversion results are compared with other water-related storage/flux estimates (i.e., GLDAS, GRACE, and precipitation), which have considerable coherence with TWS at both temporal and spatial scales. The results indicate obvious annual variations in TWS changes in north Australia in contrast to inappreciable seasonal hydrological signatures in other vast arid zones. Hydrological wet/dry conditions are quantified with drought severity index (DSI) datasets derived from multiple means and the joint-based DSI datasets temporally agree with the other datasets and correspond well with precipitation anomalies in most watersheds. In addition, the jointly inverted TWS estimates are used to declassify multifarious hydroclimatic features, and multi-source hydrometeorological datasets are used to attribute interannual TWS changes. Our study contributes to better observing the water cycles for the hydrological community and illuminates more application prospects in the climate sciences.
