Abstract A new way of coupling the Integrated Forecasting System (IFS) atmosphere model and the Nucleus for European Modelling of the Ocean (NEMO) ocean model based on an integrated single executable system with a common time step loop is presented. Details of the technical implementation are presented to give a fairly complete overview of how the IFS and the NEMO models interact in the single executable system. Initial technical performance testing is showing similar or better performance than the existing OASIS3 based system and potential for coupling at high resolution. Some potential improvements to the new system is discussed.
