The global Naval Coastal Ocean Model NCOM is a 18 degree global application of NCOM developed by the Naval Research Laboratory NRL for use at the Naval Oceanographic Office NAVOCEANO as part of an assimilative ocean model nowcastforecast system. Global NCOM is the first operational global ocean model that has sufficient resolution to be eddy-permitting. Global NCOM supports predictions of ocean currents, temperatures, salinity, sea surface height, and sound speed both directly and by providing initial and boundary conditions for higher-resolution nested ocean models. The forecast system addresses Navy requirements for Numerical Modeling METOC 9801, High Resolution Surface and Subsurface Currents METOC 9308, Littoral Salinity Prediction METOC 9902, and Air-Sea Drift Prediction METOC 9115. This validation test report describes global NCOM, its use in an assimilative forecast system, and evaluation of assimilative and non-assimilative products using independent climatologies and observations.
