The environment is a critical factor to the safe, effective operations of the U.S. Navy. In support of our global peacekeeping mission, the fleet must have timely and accurate forecasts of environmental conditions from the top of the stratosphere to the bottom of the ocean, 24 hours a day, 7 days a week. The hub of this support is the Fleet Numerical Oceanography Center (FLENUMOCEANCEN) located at Monterey, California. As the navy's primary operational processing center for global oceanographic and atmospheric analyses and predictions, FLENUMOCEANCEN provides numerical environmental products to meet the needs of the navy, as well as a full spectrum of oceanographic products to support the Department of Defense. All products are based on the center's extensive global atmospheric and oceanographic database, sophisticated long-range forecast models, and tailored tactical decision aids in support of specific weapons and sensor systems. This paper briefly describes FLENUMOCEANCEN's data sources, computer systems, atmospheric and oceanographic models, applied products, and distribution systems.

The United States has several meteorological, oceanographic, and satellite operational processing centers (OPCs) in the military and civilian sectors. Separate cooperative and complementary military and civilian OPCs provide sufficient redundancy for backup purposes; permit the development of state-of-the-art forecasting schemes, such as the ensemble technique; and ensure the diverse environmental needs of military and civilian users are met with the most efficient use of resources. The effective collaboration of the military and civilian OPCs has resulted in the development of a truly national meteorological and oceanographic resource not attainable within any single agency.
