CEMS-Flood

CEMS-Floods include two operational services, both operated by ECMWF who have the responsibilities of running the forecasts, post-processing, and hosting the associated information system platforms.

EFAS is the European Flood Awareness System. It is operational since 2012 in collaboration with several European organisations responsible for producing and providing the flood information. It provides pan-European overview maps of flood probabilities up to 15 days in advance, seasonal streamflow outlooks up to 3 months ahead, and flash-flood risk.

GloFAS is the Global Flood Awareness System. It is operational since 2018 and provides global overview maps of flood probabilities up to 30 days in advance and seasonal streamflow outlooks up to 4 months ahead.

These wiki pages describe some of the main CEMS-Floods products and services, including product descriptions, system versioning, and data access.

The CEMS-Flood wiki is split into three main branches, which you can see page trees for below.

• EFAS: For information related specifically to the EFAS system, its detailed documentation and product descriptions, etc.
• GloFAS: For information related specifically to the GloFAS system, its detailed documentation and product descriptions, etc.
• CEMS-Flood Service User Guide: For more general information on our CEMS-Flood systems that are not EFAS/GloFAS Specific. Documentation in this branch of the wiki includes: data availability, data structures/formats, data access, how to work with our data, and user support.

There is an additional branch of the wiki relating to CEMS-Flood Development and Outreach, where you can find out more on our publications and studies
