Overview of the NRL Coupled Ocean Data Assimilation System

Abstract

Advanced DA Technique Based on Optimal Estimation Theory. Oceanographic version of MVOI method used in NWP systems Lorenc (1981), Daley (1991). Simultaneous analysis of five ocean variables: temperature, salinity, geopotential, and u-v velocity components (T, S, omega, u, v). Developed as part of the coupled modeling projects at NRL MRY (COAMPS and NOGAPS/POP) Flexible System. Supports variety of map projections performs multi-scale analyses on nested, successively higher resolution grids. Initialize/update ocean forecast model or run stand-alone. 2D analyses of sea ice and SST (NWP boundary conditions), 3D temperature and salinity analysis (geostrophic currents), 3D MVOI sequential incremental update cycle.
