Long-term Goals
To develop a capability for optimal ocean data assimilation
R&D Objectives
Develop:
- a modular ensemble
data assimilation system;
- improved ensemble-based
algorithms that are suitable for practical data assimilation;
- methods for
improved estimation of model-errors and observation-errors;
- methods for the design of optimal observing
systems.
Project Highlights
- Proposal of the
Deterministic Ensemble Kalman Filter (DEnKF); a new formulation of the EnKF
that boasts the simplicity and versatility of the traditional EnKF and the performance of ensemble square root
filters (Sakov and Oke 2006).
- Development of a
modular ensemble-based assimilation system (Oke et al. 2005) that has
been applied to a range of ocean models including a global model
developed under Bluelink; a seasonal prediction model run by
the Bureau of Meteorology, POAMA; and
a series of regional models.
