Abstract
This presentation will give an overview of GFZ's activities within the GRACE-FO Science Data System (SDS) including the current status of Level-2 and Level-3 products. It will also provide a high-level summary of the ongoing RL07 reprocessing campaign. First GFZ RL07 Level-2 products are expected to be published shortly after the GSTM2026; compared to the currently operational GFZ RL06 time series, they show a significant reduction of noise (> 30 %) and more realistic formal error estimates.
This talk will provide a status update on Level-2 data processing at JPL. Included will be an overview of data products currently delivered to the community, focusing on the operational RL06.3 GRACE-FO fields. Assessments of data quality and error levels, along with detailed discussions of the solution strategy will...

We present the GRACE and GRACE-FO Level-2 and Level-3 products generated at CSR, evaluating their quality using standard metrics. We also report on the RL07 reprocessing of GRACE and GRACE-FO data, which incorporates updated Level-1B observations, reference frames, background models, instrument calibrations, and proces...

While monthly Level-2 products of GRACE/-FO are widely used as essential climate variables for mass-transport studies, published processing chains and intermediate outputs are often insufficiently documented for transparent diagnostics, method intercomparison, and fully reproducible re-solving. Building on existing use...

The Gravity Recovery and Climate Experiment Follow-On (GRACE-FO), launched in May 2018, provides invaluable information about mass change in the Earth system, continuing the legacy of GRACE. Fundamental requirements for successful mass change recovery are precise orbit determination and inter-satellite ranging, determi...

GFZ aims to distribute a reprocessed and improved RL07 Level-2 gravity field time series in the last quarter of 2026. Most of these improvements have been developed within the Research Unit “New Refined Observations of Climate Change from Spaceborne Gravity Missions” (NEROGRAV) funded by the German Research Foundation...

We present the status of the low degree gravity coefficients C20 and C30 derived from satellite laser ranging and distributed as Technical Note 14. This includes comparisons to solutions from other centers, our group’s new long-term C20 solution that is independent of the background gravity model, and new length-of-day...
