—Assimilation of drifter data in a circulation model of the Indian Ocean has been explored in the study. Assimilation has been effected using the approach of nudging. The impact of such assimilation has been quantified by comparing the sea level anomalies simulated in runs with and without assimilation against independent observations derived by satellites.(More)
—Ensemble optimal interpolation, a simplified and computationally inexpensive version of ensemble Kalman filter, has been used to assimilate satellite-derived sea level anomaly and sea surface temperature in an Indian Ocean circulation model. In order to cut off the long-range spurious covariances, a localization technique has also been used where an(More)
