The following is a description of the pre-operational release of EFAS v5.2, which will be made available from 04 July 2024 in a test phase. EFAS v5.2 is expected to be launched operationally in August 2024. For an overview of other EFAS releases, please see: the EFAS versioning system.
To test the pre-operational EFAS v5.2 version, you must access the EFAS Stage Platform: https://stage.efas.eu/efas_frontend/#/home
Please submit any feedback you have on EFAS v5.2 updates using the EFAS feedback form: https://european-flood.emergency.copernicus.eu/en/form/feedback
Summary
EFAS v5.2 introduces several minor changes to the system, including:
- Revised Notification criteria for Formal and Informal notifications:
- optimized criteria for the issue of Formal and Informal notifications are based on a new methodology for the computation of the total probability of exceedance of the 5r RP threshold of the grand ensemble encompassing all Numerical Weather Predictions.
- improved definition of the area of validity of Formal and Informal notifications.
- revised layers in the EFAS Map Viewer: link to new calculation page: placeholder - EFAS 5-year exceedance probability and placeholder - EFAS Flood Probability
- improved EFAS notifications email to include a link to a preview feature in the Notifications Archive Dimitar Tasev
- optimized criteria for the issue of Formal and Informal notifications are based on a new methodology for the computation of the total probability of exceedance of the 5r RP threshold of the grand ensemble encompassing all Numerical Weather Predictions.
- FID now on rapid impact assessment layer? Dimitar Tasev
- Reporting point updates: label change, probability tables updates, updates to hydrographs, Juan Pereira Colonese & Corentin Carton de Wiart changes also need to be made in: placeholder - EFAS Reporting Points page. Reporting points alert levels are now based on the new total probability. For each point new total probability tables and combined hydrograph are shown.
- Stations metadata updates - Stations metadata have been updated to better align them with the hydrological data collected by EHDCC. Cinzia Mazzetti
Update flood protection dataset for the EFAS Rapid Risk Assessment, - Calum Baughcheck if only internal?- Major rivers layers Juliana Disperati / Dimitar Tasev to explain changes
- 'new' ftp process for EFAS? Arthur Ramos to confirm
This upgrade of EFAS has no impact on the EFAS modelling results.
