Data Assimilation of Remotely Sensed Measurements in Large-Dimensional and Nonlinear Environmental Models

Noisy measurements and uncertain model output are merged in the process of data assimilation. In environmental applications with remotely sensed measurements the problem is constrained by large dimensionality and nonlinearity of the model. In a number of application examples candidate approaches for dealing with the constraints will be presented.
