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 NOGAPSPOP Flexible System. Supports variety of map projections performs multi-scale analyses on nested, successively higher resolution grids. Initializeupdate 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.
