The World Meteorological Organization (WMO) has released its State of Global Water Resources 2024 report. The report highlights the essential role of remote sensing in monitoring global freshwater resources, including results contributed by the GIS team on satellite altimetry-derived river discharge. Without these satellite-based estimates, large regions of Asia and Africa would remain largely unmonitored.
The underlying datasets used in the report were developed by the GIS team and collaborators and are described in the following publications:
- SAEM: Satellite Altimetry-based Extension of global-scale in-situ river discharge Measurements – https://doi.org/10.5194/essd-17-2063-2025
- RSEG: Remote Sensing-Based Extension of GRDC Discharge Time Series - A Monthly Product with Uncertainty Estimates – https://doi.org/10.1038/s41597-024-03078-6
