Global HYCOM and Advanced Data Assimilation

Abstract

The long-term goal is to use a HYbrid Coordinate Ocean Model (HYCOM) with data assimilation in an eddy-resolving, fully global ocean prediction system with transition to the Naval Oceanographic Office (NAVO) at .08 equatorial resolution in 2006 and with .04 resolution by the end of the decade. Equatorial resolution of .08 (.04 ) increases from 9 km (4.4 km) at the equator to 6 km (3 km) at 47 latitude. The Arctic is covered by a bipolar PanAm grid. At 59 N it matches the spherical grid covering the rest of the global ocean. The model will include shallow water to a minimum depth of 10- 20 m and will provide boundary conditions to finer resolution coastal models that may use HYCOM or a different ocean model.
