The U.S. Navy Operational Global Ocean
Model (NCOM) developed and maintained by the Naval Oceanographic
Office (Baron et al. 1 & 2) is used as the basis for the OPC
Global Ocean SST & Currents Forecast. NCOM is a 1/8 degree
resolution model that serves as the Navy's operational global
Nowcast/Forecast system. NCOM is based on the Princeton Ocean
Model (POM). The surface boundary conditions for the NCOM model,
including wind stress, heat flux, and salt flux are provided by
the Navy Operational Global Atmospheric Prediction System
(NOGAPS). The Navy Modular Ocean Data Assimilation System (MODAS)
provides the data assimilation for NCOM including SSH and SST. For
more information about NCOM see:
