Anticipation and preparedness of large-scale flood events play a key role in mitigating their impacts and optimizing the strategic planning of water resources. Although a lot of countries have well-established systems for river monitoring and early flood warning, an increasing number of inhabitants is affected by floods every year. The Global Flood Awareness System (GloFAS) has been set up providing an overview on upcoming floodings in large world river basins.
On 16/17 January ECMWF hosted a hackathon aimed at improving GloFAS by developing innovative ideas and approaches. More than 3.5 TB of data have been prepared, partly served in an OGC-compliant Web Coverage Service Standard (WCS) for easier data access and retrieval. In the EarthServer-2 project, this WCS service is currently set up at ECMWF and further institutions in Great Britain.
