Data Assimilation Meetings at Reading

Assimilating Eddy covariance measurements with the Data Linked ECosystem (DALEC) model: An ill-posed problem.
Techniques from four-dimensional variational data assimilation are applied to simple models of the carbon cycle. Using synthetic flux tower measurements together with a linearization of DALEC model we show that the assimilation problem is highly ill--posed, and that parameters related to slow processes are not observable. We study the impact of Tikhonov regularization method and model reduction on the quality of the analysis and on the reduction of the uncertainty.
