What is OpenIFS/AC?

OpenIFS/AC is an extended version of the ECMWF OpenIFS model that allows the additional simulation of atmospheric composition (atmospheric chemistry and aerosol processes).

The standard OpenIFS model does not include treatment of chemical and aerosol processes. Adding this functionality within OpenIFS/AC opens up new scientific applications of the model, e.g. to study the impact of atmospheric composition on NWP or interactions between atmospheric composition and the climate system. 

How to access OpenIFS/AC

OpenIFS/AC is provided as an add-on to the OpenIFS model. Using OpenIFS requires a software licensing agreement with ECMWF. More information on OpenIFS licensing and model software requirements can be found in the OpenIFS User Guide and the OpenIFS Home page. 

How to use OpenIFS/AC

The necessary steps to install, build and run OpenIFS/AC for a simple forecast case are described on a dedicated page linked to below:
