Modifications to the Ocean-LETKF data assimilation system to support ensemble-based data assimilation with HYCOM
Abstract
An ensemble-based ocean data assimilation system using the Local Ensemble Transform Kalman F ilter (O cean-LETKF) h as b een d elivered t o N RL f or t rial im plementation w ith t he Hybrid Coordinate Ocean Model ( HYCOM). As most of the testing has previously be"en performed using a z*-coordinate model configuration at climate scale resolutions (~~x~~), additional modifications must be made t""o allow an efficient assimilation scheme applied to the 1/12~ and ( potentially) 1/25~ HYCOM configurations, both using a hybrid ver"tical coordinate.
