Algorithmic Optimal Control - CO2 Uptake of the Ocean

personal page

PhD thesis:

We present an iterative approach called One-Shot method to solve data assimilation problems to identify parameters of parts of the climate system. Those are for example ocean or atmospheric models. The goal is to obtain feasibility and optimality by simultaneously updating the state, the adjoint and parameter values. Numerical results are shown first on the basis of a least squares fit of the Rahmstorf North Atlantic thermohaline circulation box model and second by optimizing parameters of a Marine Biogeochemical Model in 3D.
