The NOGAPS Forecast Model: A Technical Description

Abstract : The Navy Operational Global Atmospheric Prediction System (NOGAPS) provides numerical guidance and products in support of a wide range of Navy oceanographic and atmospheric requirements. The forecast model component of NOGAPS is the heart of the system and represents a multiyear development effort by the scientists of the Naval Oceanographic and Atmospheric Research Laboratory's Atmospheric Directorate. Because many other Navy oceanographic and atmospheric research effort depend on NOGAPS for environmental inputs, there is continuing demand for detailed technical descriptions of the forecast model's physical, mathematical, and computational processes. Only with this documentation can other Navy scientists understand research results influenced by NOGAPS output products. Because such numerical weather prediction systems as NOGAPS are constantly evolving, periodic updates to system documentation are also a key to supporting future Navy environmental research.
