OpenIFS is provided free for educational and research use under standard terms for an ECMWF software license. It is not open source nor public domain software.
OpenIFS is licensed per institution and requires an authorative signature from the host institution. This should not be seen as a barrier to use of OpenIFS, the support team at ECMWF will answer any licensing related queries. We only ask users to complete a short form registering their intent (see Releases to register your interest and request a license for OpenIFS).
Licensed users are granted write access to the user forums on this wiki site and can create their own 'space' under User spaces, which we encourage for sharing information with other OpenIFS user groups.
We also provide a contributors license for code written by users that we would like to include in OpenIFS or IFS.
