Validation Test Report for the 1/8 deg Global Navy Coastal Ocean Model Nowcast/Forecast System

摘要

The global Naval Coastal Ocean Model (NCOM) is a 1/8 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 nowcast/forecast 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.
