Access requirements

OpenIFS is licensed software and using the model requires your affiliation with an institute which has signed the ECMWF OpenIFS software licence agreement.

In order to access the model sources and other required data packages, you need to have a peronsal ECMWF account which you can create on the ECMWF web site or by clicking here.

If you are a new model user then you should first contact OpenIFS support, by emailing openifs-support@ecmwf.int, requesting access to OpenIFS by stating your full name, your affiliation and related email address, and your ECMWF account user name. OpenIFS staff will then activate OpenIFS user policies for your personal ECMWF account. We may request additional verification of your affiliation with your licensed institute prior to giving access.
