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 ...

Reprocessing of KBR1B data on GRACE-FO and its advantages
2022<p><span lang="en-US">The K-Band Ranging system (KBR) is the key payload to measure the inter-satellite distance variations with the accuracy of sub-micrometers in GRACE and its successor GRACE-FO missions.

Exploring Earth's space environment with the GRACE-FO mission
2020<p>As part of its attitude and orbit control system, the GRACE-FO satellites carry vector magnetometers. After appropriate calibration and characterisation of artificial magnetic disturbances, the mean residual to the high precision magnetic models is below 1 nT during times of geomagnetic quiet conditions.

Spatio-temporal Wiener filtering of GRACE/-FO solutions
Monthly estimates of the Earth’s gravity field based on the GRACE/-FO missions have enabled decisive progress in the quantification and understanding of mass transfers in the Earth system. However, raw level 2 GRACE/-FO solutions are affected by large errors in the form of North-South stripes.Paul Rebischung +4 more

GRACE and GRACE-FO constraints on 3D GIA models
Glacial isostatic adjustment is the response of the solid Earth to past ice sheets. It is the largest secular gravity increase in GRACE and GRACE-FO data. Models of GIA are used to correct GRACE observations for ice mass and sea level change, but in areas where GIA is the main signal GRACE data can be used to constrain GIA models.Wouter van der Wal +4 more

GRACE and GRACE-FO Mascons for Studying Ocean Dynamics
We have developed a specialized set of CSR mascons for ocean dynamics studies.  The standard GRACE/GRACE-FO mascons over the ocean represent ocean bottom pressure.  Thus, they have contributions from the average atmospheric pressure change over the ocean, the barystatic (global mean) mass change and the geographically variable ...Mark E.

GRACE-FO: science results, mission status and outlook
Since 2018, the GRACE Follow-On satellite mission, a partnership between NASA (US) and GFZ (Germany), is continuing the unique essential climate data record of mass change across the Earth system initiated in 2002 by the GRACE mission (2002-2017).Felix Landerer +8 more
