The combined GRACE & GRACE-FO data records now span over 20 years and provide unique observations of monthly to decadal global mass changes and transport in the Earth system derived from temporal variations in the Earth’s gravity field. These observations have become indispensable for climate-related studies that enable process understanding of the evolving global water cycle, including ocean dynamics, polar ice mass changes, and near-surface and global ground water changes.
In this presentation, the project team will provide the community and science team an overview and summary updates on (1) some recent science and applications highlights, (2) key data processing and calibration campaigns and results since 2021, with a particular focus on the accelerometer data, and (3) the mission plan to operate and collect high-quality science data through the intensifying solar cycle 25, aiming for continuity with future mass change missions. More detailed presentations on each topic will follow this talk, and there will be an open forum for feedback and discussions on the status, findings, and proposed plans.
