Global Terrestrial Water Storage Anomaly Dataset Now Operationally Available via Copernicus

,
A new global Terrestrial Water Storage Anomaly (TWSA) dataset became operationally available via the Copernicus Climate Data Store in April 2026. Developed through a decade of European GRACE/GRACE-FO collaboration, the dataset provides satellite-based observations of water storage changes across Earth’s surface and subsurface, supporting climate monitoring and future groundwater applications.

Meet Yuting Cheng – Early Career Scientist

, , ,
Yuting is a postdoctoral researcher at the Royal Observatory of Belgium working on the ambitious ESA GENESIS project. Her research centers on a unique satellite co-locating all four space geodetic techniques, creating a unified reference point in space. Her work contributes to improving the precision and stability of the International Terrestrial Reference Frame, while exploring how these observation systems perform together under novel space conditions.
