EFAS version 4.8 introduces changes associated with the 48r1 Numerical Weather Prediction (NWP) model configuration (resolution and extended range) that may potentially impact the results of EFAS.
EFAS version 4.8 introduces changes associated with the 48r1 Numerical Weather Prediction (NWP) model configuration (resolution and extended range) that may potentially impact the results of EFAS.

A minor release of the Copernicus Emergency Management Service (CEMS) European Flood Awareness System (EFAS), version 4.8, will be launched operationally on Tuesday 27 June 2023.

CEMS EFAS v4.8 integrates changes in its Numerical Weather Prediction Forcing, with the use of ECMWF ensemble forecasting system version 48R1. The 48R1 ENS has a spatial resolution of 9km compared with 18km for previous ENS versions.  The configuration of the NWP input to CEMS EFAS remains unchanged. More details on the changes can be found in the Implementation of IFS Cycle 48r1.

For more information about the release of CEMS EFAS which includes also other minor changes, please refer to the dedicated wiki pages after the release. Questions and feedback can be addressed to the EFAS team via the EFAS Contact form.
