Zsoter, Ervin ; Harrigan, Shaun ; Baugh, Calum ; Prudhomme, Christel
On 5 November 2019, the Global Flood Awareness System (GloFAS) was upgraded to version 2.1. The upgrade includes the release of a revised global hydrological reanalysis based on ECMWF's ERA5 atmospheric, land surface and ocean wave reanalysis. The GloFAS reanalysis is freely and openly available to users through the Copernicus Climate Change Service (C3S) Climate Data Store. The upgrade also introduced a new set of river discharge re-forecasts and revised flood thresholds. In addition, new global flood risk assessment products (summary flood extent and flood impact overview), flood summary maps and ancillary web products have been developed to help users to interpret GloFAS forecasts. GloFAS is the flood component of the Copernicus Emergency Management Service (CEMS) Early Warning Service, for which ECMWF is the computational centre. For more details on GloFAS, see Box A.</p>
