Developing an ensemble based Data Assimilation System for an operational forecasting system of the North and Baltic Seas.
The circulation model operated by the German Federal Maritime and Hydrographic
Agency has been recently augmented by an ensemble-based data assimilation system.
We discuss some aspects of the implementation of a Kalman-type filtering, coded within the Parallel Data Assimilation Framework, for assimilating NOAA's
satellite sea surface temperature (SST) and in situ T and S observations.
In particular, we show how a proper approximation of the model and data
error statistics allows to improve the system's forecasting skills.
