OpenIFS main help
- Technical Description: get an overview of the parts that make up the model and some of the underlying scientific concepts (largely independent from model release)
- OpenIFS User Guides: please see the user guides of all supported model releases for instructions on how to install and run OpenIFS.
- How-to articles: find out how to do a number of things such as altering the code, changing model output, visualizing the output, debugging and so on.
- Known issues: lists various known problems and their resolution.
- Frequently Asked Questions
- User Forums. You can search the User Forums for answers or ask a message or question.
IFS scientific & technical documents
ECMWF has many publications online, including user manuals, tutorials, seminar proceedings, technical reports and the newsletter, amongst other documents.
The full list of ECMWF publications can be found at: http://www.ecmwf.int/en/research/publications.
A more general complete description of the ECMWF Integrated Forecast System (IFS) can be found in the ECMWF Forecast User Guide.
IFS manuals for all model cycles
IFS manuals are available here.
The manuals on 'Dynamics & Numerical Procedures', 'Physical Processes' and 'Technical & Computational Procedures' are the ones most appropriate for OpenIFS.
