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