Making the best use of GRACE, GRACE‐FO and SMAP data through a constrained Bayesian data‐model integration [PDF]
, 2023 The Gravity Recovery and Climate Experiment (GRACE, 2003–2017) and its Follow-On mission GRACE-FO (2018-now) provide global estimates of the vertically integrated Terrestrial Water Storage Changes (TWSC).

, 2020 <p>We will present a high-level overview of the GRACE Follow-On mission status, science and instrument performance, and future plans. GRACE-FO has now delivered over two years of monthly gravity field and mass changes map since Jun-2018. These unique observations extend the global mass change climate data record to almost two decades, and
