<p style="background-image:initial;background-repeat:initial"><a name="_GoBack"></a>Over the years, operational
data assimilation and forecasting systems are becoming more and more complex.
Complexity arises from advances in data assimilation methodology, such as
weak-constraint 4D-Var, ensemble data assimilation methods, and hybrids between
those. Another source of added complexity is the development of more and more
complex Earth system representations in the operational NWP systems,
including land surface, waves, sea-ice, ocean and atmospheric composition.
The supercomputers we use to run these forecasting systems are also becoming
more and more difficult to use efficiently with many more cores than in the
past and possibly heterogeneous architectures. Finally, in many cases, the
systems are shared by several institutions, with more and more scientists and
developers working in parallel, often adding to the complexity of maintaining
the codes. </p>
<p style="background-image:initial;background-repeat:initial">To address this increasing complexity, a new
software infrastructure, the object-oriented prediction system (OOPS) has
been developed. It is developed and validated with simplified models, and
several conventional and experimental data assimilation algorithms have been
implemented. The components of the operational IFS are progressively being
moved into the new structure. The design choices for the new software
infrastructure will be presented. </p>
