Marie-Curie Intra-European Fellowship for Career Development (IEF) on the initialisation of global decadal climate forecasts - a new challenge for multi-scale data assimilation
Decadal prediction has emerged nowadays as a main concern in the climate science community. Improving the forecast on the time scales of 10-30 years is expected to carry tremendous value for the society, supporting plans for infrastructure upgrades, financial decisions or energy policies.
European funded project:
are in between the seasonal forecast (6-12 months) and the climate prediction (on the scale of a century) and share a number of physical and dynamical features of both. The decadal time range is at the confluence of forecasting, such as that performed in seasonal prediction, having a marked predictable signal in the initial state and the long term climate prediction driven mainly from external forcing and fully independent from the initial state. Refined observing networks for the ocean component are now available (see e.g. the ARGO project
, or SMOS mission
of ESA) and contribute also to promising future improvements in forecast quality.
is the field of geosciences that study the problem of state estimation of evolving, possibly chaotic, dynamical system on the base of incomplete, inhomogeneous and noisy observations. Data assimilation is regarded nowadays with strong interest from the climate science community, because of the potential to improve decadal prediction by introducing adequate initialization process for the whole climate system, making the best use of the current observations. Several fundamental unresolved questions need to be addressed to adapt existing data assimilation algorithms as well as to develop new strategies for the Earth system models used in decadal prediction. Testing different data assimilation approaches and contributing to the current open debate on how to improve initialized decadal prediction are the main motivations of the proposed research.
The project's ultimate goal is the implementation of a state-of-the-art data assimilation technique for the initialization of the IC3 EC-Earth model.
