Mission: Build and sustain a global climate observing system that will respond to the long- term observational requirements of the operational forecast centers, international research programs, and major scientific assessments. NOAA’s Office Of Climate Observation The Ocean Component

Climate Observation Program -- Partnerships are Central Integration Along Three Axes Climate Services U.S. Integrated Ocean Observing System International Implementation U.S. Integrated Ocean Observing System System Approach to Climate Observation A global observing system by definition crosses agency and international boundaries. The potential exists for both benefits and responsibilities to be shared by many.
