Abstract

In this study we investigate the impact of a wide swath altimeter instrument on the reduction of model error, due to uncertainties in bathymetry, by an ensemble method. A simplified scheme for the observation tool has been used, and in this framework the impact of the roll of the platform, which leads to correlated errors on the sea level measurement, is also investigated. It appears that a wide swath altimeter is valuable in coastal areas even with large correlated roll errors, as long as the data assimilation process is adapted to the correlated errors.
