OpenIFS

The OpenIFS project at ECMWF provides a version of the ECMWF IFS model for use at institutes and universities, for research and education. See 'About OpenIFS' for more information.

A licence is required. The licence is free and a site license. No personal licenses are provided.

Register your interest

The first step to obtaining a licence for OpenIFS is to register your interest. All institutes & universities may apply.

Please complete our registration form to the right. This will be sent to the OpenIFS team who will review the request and respond as soon as possible. ECMWF will review the request to ensure the proposed use is appropriate for the model. OpenIFS support is limited and ECMWF may refuse license requests if the total number of licenses exceeds our support capacity. Preference may be given to ECMWF member states and new or existing collaborations.

Any queries before completing the form can be sent to: openifs-support@ecmwf.int.

License

OpenIFS is provided free to institutes (e.g. universities) for educational and research use (only) but it is not open source nor public domain software and we do not provide personal licenses.

Licensing of OpenIFS should not be seen as a barrier to use of the model. Please contact openifs-support@ecmwf.int for any queries.

See Licensing for more details about the licence terms.

Release files

The OpenIFS model is available as tarfiles from the ECMWF ftp site along with example initial conditions and additional software. The ftp site is password protected and users are provided with the password when the license has been completed.

OpenIFS is also available as a Git repository for selected developers and users. For more details please contact: openifs-support@ecmwf.int.
