A new satellite-based study has reconstructed suspended sediment concentration across the Yellow River over nearly 40 years, revealing not only a long-term decline but also a recent shift in that downward trend. By combining decades of with a newly developed retrieval model, the research shows how reservoirs, tributaries, vegetation recovery, and check dams have collectively reshaped sediment patterns along one of the world's most sediment-laden rivers.

A new study shows that the Surface Water and Ocean Topography (SWOT) satellite can track lake volume changes across China with strong accuracy while greatly improving the monitoring of small lakes that were often missed before. By combining synchronous measurements of lake level and area with supporting bathymetric data, the researchers found clear seasonal patterns and an overall rise in lake volume, driven mainly by natural and larger lakes.

A research team from the Aerospace Information Research Institute of the Chinese Academy of Sciences (AIRCAS) developed a satellite-based method to analyze the life cycle of ocean eddies forming along Arctic sea-ice edges. By combining sequential synthetic aperture radar (SAR) images with hydrodynamic modeling, the researchers reconstructed surface current fields and retrieved key dynamical parameters of a polar eddy throughout its evolution. The approach provides new insights into ice-edge ocean dynamics and offers a powerful tool for studying interactions between sea ice, ocean circulation, and climate processes.
