Abstract :
This work is concerned with the reconstruction of unknown atmospheric distributions of species´ concentrations and the simultaneous identification of unknown physical parameters. The physical and chemical processes are represented by a simplified chemical transport model. The second focus of the contribution lies on the development and the application of the adaptive techniques to the resulting inverse problem. The underlying theoretical framework is the Dual Weighted Residual (DWR) method for goal-oriented mesh optimization.
