NCOM American Seas

The Naval Oceanographic Office (NAVOCEANO) operational ocean prediction system for the Gulf of Mexico and Caribbean is based on the NRL-developed Navy Coastal Ocean Model (NCOM). With resolution of 1/36 degree (~3km) horizontal and 40 levels in the vertical. This capability provides 4-day forecasts at 3-hour time steps, updated at 00Z daily. The NetCDF files contain ocean temperature, salinity, eastward and northward currents, and elevation, along with the atmospheric forcing fields provided over this domain by a 15 km application of the Navy's COAMPS model. The AMSEAS ocean prediction system assimilates all quality controlled observations in the region including satellite sea surface temperature and altimetry, as well as surface and profile temperature and salinity data using the NRL-developed Navy Coupled Ocean Data Assimilation (NCODA) system. Boundary conditions are applied from the NAVOCEANO operational 1/8 degree global NCOM.
