Assimilation of high-frequency radar data in the east Chukchi Sea
The maximum-likelihood ensemble lter (MLEF) is an efficient technique of data assimilation related to both 3D-variational (3Dvar) and Ensemble Kalman Filter (EnKF) methods. We demonstrate the utility of MLEF by assimilating high frequency radar (HFR) data into a realistic model of the east Chukchi S...
