What if two GRACE-FO data assimilation systems produce nearly identical terrestrial water storage estimates - but tell different stories about what is happening underground? 🌍💧 New paper in Water Resources Research: doi.org/10.1029/2025... #DETECT #GRACE-FO #DataAssimilation

🌍 At EGU General Assembly 2026? Superconducting gravimetry meets hydrology ⚖️💧 Talk tomorrow (Fri) on our new gravimeter near Bonn and what it reveals when compared to CRC 1502 DETECT model output. 📍 meetingorganizer.copernicus.org/EGU26/EGU26-... #EGU26 #SuperconductingGravimetry #CRC1502DETECT

💭 Comparing large-scale hydrological models & satellite gravimetry (GRACE/GRACE-FO) with superconducting gravimeters is still challenging. 🔬 More gravimeters + better satellites/models → seamless water storage monitoring. 📄 EGU: meetingorganizer.copernicus.org/EGU26/EGU26-... #Geodesy #EGU2026

🍎⚖ #DETECTapple: Tiny gravity changes, huge insight! @aquasong.bsky.social studies how iGrav043 near Bonn tracks water storage, incl. water taken up by trees 🌱💧. A 2-yr iGrav vs eCLM comparison agrees. GRACE-FO assimilation did not improve the match. 🌎 sfb1502.de/images/Newsl... #CRC1502 #DETECT

⏳ Almost 20 yrs of 𝗚𝗥𝗔𝗖𝗘/-𝗙𝗢 data assimilation tell a fascinating story 🌍💧. Read our newest HESS review here: hess.copernicus.org/articles/30/...

A review of current best practices and future directions in assimilating GRACE/-FO terrestrial water storage data into numerical models

Abstract. Water cycle reanalyses, generated by integrating observations into hydrological and land surface models, provide long-term and consistent estimates of key water cycle components. Reanalyses ...
