GEOGLOWS Streamflow
GEOGLOWS is the Group on Earth Observations' Global Water Sustainability program. This tool is the viewer
for the GEOGLOWS programs global hydrologic model, now on version 2. Please refer to the
data documentation site and the
GEOGLOWS program home page for more information.
The model provides a few main outputs:
- Daily 15 day ensemble forecasts at 3 hour time steps
- Retrospective daily average flows from 1 January 2024 to present with 5-12 days of lag
- GIS datasets for the streams and catchments
- Model configuration files
- River context information such as river names and country
