EFAS v5.0 hydrological reanalysis

The EFAS v5.0 hydrological reanalysis dataset is the new generation of the hydrological reanalysis produced within the Copernicus Emergency Management Service including maps of discharge (in m3/s) with European extent at 1 arc minute (~1.5 km) grid resolution and 6-hourly time step. The dataset contains several updates in comparison to the previous streamflow reanalysis including a higher spatial resolution, a complete new set of input maps for the catchment physical properties, major improvements to the open-source hydrological model LISFLOOD and a new model calibration. Furthermore, for ungauged catchments, a parameter regionalization was performed transferring parameter sets from donor catchments based on spatial and climatological proximity to ensure the best possible simulation of river flows for all catchments in the European domain. The model set up, which was used to generate this dataset, will also be part of the operational Copernicus Emergency Management Service EFAS ensuring a regular (twice daily) update in near-real time for this dataset. Detailed technical information on the dataset can be found on the EFAS wiki.
