Data Assimilation in RAIA

Final Report Summary - RAIA.DA (Data Assimilation in RAIA)

The RAIA.da project concerned operational hydrodynamic forecasts in the north-western Iberian Peninsula. The objective was to improve forecasts of an implementation of the ROMS model, run by the CIIMAR group in Porto (Portugal) in the framework of the RAIA and RAIA.co projects.
The original (deterministic) model needed to be replaced by an ensemble of models, each member of the ensemble being a different realization in the space of all possible models (i.e. different parameters, atmospheric forcing fields etc). Furthermore, the ensemble would be used to assimilate observations and improve the forecasts. Finally, a set of particular multi-model data assimilation techniques called “super-ensembles” would be further studied and implemented.
