The Navy Operational Global Atmospheric Prediction System NOGAPS is the Department of Defenses DoDs high-resolution global numerical weather prediction NWP system. Its development and operation is a joint activity of the Naval Research Laboratory NRL and the Navys Fleet Numerical Meteorology and Oceanography Center FNMOC. NOGAPS is a complete operational forecasting system that includes data quality control, tropical cyclone bogusing, operational data assimilation, balanced initialization, and a global forecast model. Operational NOGAPS forecasts currently consist of high-resolution T239L30 six-day forecasts every 6 hours and once-a-day extended ten-day guidance using the FNMOC ensemble T119L24. These forecasts are distributed to numerous defense and civilian users, and are used as input for numerous DoD environmental and application systems. Examples include the Navys Coupled Ocean-Atmosphere Mesoscale Prediction System COAMPSTM FNMOCs ocean wave, sea ice, ocean thermodynamics, and tropical cyclone models aircraft and ship-routing programs.
