What is OpenIFS

OpenIFS provides academic and research institutions with an easy-to-use version of the ECMWF IFS (Integrated Forecasting System). OpenIFS provides the forecast capability of IFS (no data assimilation), supporting software and documentation. OpenIFS has a support team at ECMWF for technical assistance but limited resources for detailed scientific assistance.

About OpenIFS provides more information about the model.

The OpenIFS model and accompanying software is intended for use on computers external to ECMWF, though member state users with time on ECMWF computers can use OpenIFS on ECMWF systems.
