Global flood monitoring with GRACE/GRACE-FO
2021<p>The German Aerospace Center and NASA's joint mission, the Gravity Recovery and Climate Experiment (GRACE) operational from 2002 until October 2017, provided measurements of Earth's gravity field anomalies. Its follow-on mission GRACE-FO, implemented by NASA and GFZ, was launched in May 2018 and continued to give us large-scale ...

GRACE-FO precise orbit determination and gravity recovery
Journal of Geodesy, 2020The gravity recovery and climate experiment follow-on (GRACE-FO) satellites, launched in May of 2018, are equipped with geodetic quality GPS receivers for precise orbit determination (POD) and gravity recovery. The primary objective of the GRACE-FO mission is to map the time-variable and mean gravity field of the Earth. To achieve this goal, both GRACE-

GRACE-FO and SLR updates from GSFC
2022<p>We present a summary of our recent work on time-variable gravity estimates derived from GRACE/GRACE-FO and satellite laser ranging (SLR). We will show analyses summarizing the impacts of the improved accelerometer transplant product on our unregularized monthly spherical harmonics and regularized mascons.

Assessment of GRACE-FO Laser Ranging Interferometer measurements
2021<p>The performance of Gravity Recovery and Climate Experiment Follow&#8208;On (GRACE-FO) laser ranging interferometer (LRI) system is assessed in both space and frequency domains. With LRI&#8217;s measurement sensitivity being as small as 0.05 nm/s<sup>2</sup> at GRACE-FO altitude we perform a ...

GRACE-FO Data Assimilation Applications and Issues
2022<p>Multiple projects now assimilate GRACE and GRACE-FO data into land surface models in order to constrain the terrestrial water storage state variables (e.g., groundwater, soil moisture, snow) in those models.&#160; This approach has been employed successfully to generate weekly, global drought and wetness indicators, among other
