Our research team applies satellite gravity, satellite altimetry, GNSS and other geodetic observation technologies to investigate the surface material migration in typical regions at multiple spatial and temporal scales. By integrating multi-source observation data and advanced signal analysis methods such as principal component analysis, singular spectrum analysis, and independent component analysis, the team deeply understands the mechanisms and evolution patterns of surface material migration, revealing the inherent connections between human activities, environment, and climate change. This research serves national demands and provides theoretical basis for environmental governance, disaster prevention, and other significant decision-making processes. The main research achievements include: constructing high-resolution point mass models for the Antarctic and Greenland ice sheets and accurately estimating their melting rates; comprehensively analyzing multiple potential factors affecting sea-level change estimation, further enhancing global sea-level closure; filling the data gap between GRACE and GRACE Follow-on using data-driven approaches, providing favorable continuity for the two generations of satellite gravity data; accurately determining the depletion rates and driving factors/mechanisms of groundwater and multi-layer soil moisture in the North China Plain using high-resolution time-variable gravity field and hydrological models, and analyzing their close relationships with surface vertical deformation; investigating land water changes and driving factors in the Pearl River Basin; analyzing the causes of extreme drought events in the Pearl River Basin and Australia.
