On April 14, 2026, the third RivEx community meeting took place online, focusing on “In situ Observations & Satellite Observations”. Simon Mischel from GRDC was invited to present on the “Role of GRDC in the framework of RivEx: Delivering the Observational Foundation”, while MJ Tourian from the University of Stuttgart gave a talk about “Rivers from Space: Monitoring Rivers with Altimetry and Imaging Satellites—Progress and Challenges”.
In his talk, Simon gave a brief introduction into the work of GRDC and highlighted the importance of ground-based (“in situ”) measurements for Earth observation. Thereby he showed how satellite data can help to extend in situ time series and how they can support data collection, such as for last year’s WMO State of Global Water Resources Report. Finally, he suggested ways in which RivEx and GRDC could collaborate in the future and develop a shared data foundation together.
The River Experiment (RivEx) is a core initiative of the Global Energy and Water Exchanges program (GEWEX), part of the broader World Climate Research Programme (WCRP). RivEx aims to improve scientific understanding of river systems as critical components of the global freshwater cycle and to address key knowledge gaps in hydrology.
