Observing System Research and Ensemble Data Assimilation Development Research Team (OREDA)

We develop ensemble-based assimilation systems of atmospheric, cryospheric and greenhouse gas data and conduct observing system research in order to evaluate observations and to study predictability. This is a cross-cutting team among the Earth Simulator Center and several programs of the Research Institute for Global Change.
