License

See Licensing for more details.

OpenIFS is provided free to institutes (e.g. Universities) for educational and research use but requires a license to be signed before access to the model code is provided. 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.

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.
