EC‐Earth is based on the Worlds leading weather prediction model (ECMWFs IFS), which is extensively verified on short time scales. EC‐Earth is closely aligned with ECWMFs seasonal forecasting system. EC‐Earth benefits greatly from continuous updates through collaboration with ECMWF. EC‐Earth can be used for predictions across time scales, ranging from weather to climate. EC‐Earth can be used to study climate feed-backs, which govern the global and regional response.

EC-Earth 3 at NSC is generally supported by Hamish Struthers ( See the Development portal webpages for detailed documentation, examples, wiki, user forums, issue tracking and bug reporting. See also SNIC EC-Earth documentation page.

How to build and run

In general, there are no system installs of EC-Earth 3. Instead, the model can be built from the unmodified source code (Subversion repository). Once registration is completed (see the official website), instructions for downloading the source code, building and running the model can be found on the EC-Earth 3 development portal: Building EC-Earth 3 on the NSC triolith system
