Implementation of the NRL Coupled Ocean Data Assimilation (NCODA) System in HYCOM

Abstract

1/12 deg Atlantic (28 deg S to 70 deg N). Running in near real-time (on Wednesday). Assimilates the satellite altimeter analysis from the MODAS operational system at the Naval Oceanography Office (NAVOCEANO). Mean SSH from the 1/12 deg MICOM (ECMWF). Vertical projection via the Cooper and Haines technique (1996, JGR). FNMOC/NOGAPS atmospheric forcing. Relaxation to the MODAS SST analysis. 10 day hindcast, 14 day forecast. Automated scripts run the system from the preprocessing of the forcing fields to the post processing of the results. Participating in the MERSEA model inter-comparison.
