The societal and economic impacts of climate variations, which concerns Indian Ocean such as Monsoon variability, dipole mode, intraseasonal variability and so on, affect the lives of nearly hundreds of millions of the world's population. The climate variations are also critical to agricultural and fisheries production, disaster, water cycle, and so on. Therefore, the benefit to be derived describing conditions, understanding mechanisms and predicting the coupled ocean and atmospheric behavior in the region is potentially huge.

To achieve comprehensive, coordinated and sustained observations of Earth system, a Global Earth Observation system of Systems (GEOSS) 10-year implementation plan has been started from 2005. GEOSS will meet the need for timely, quality long-term global information as a sound decision making, and will enhance delivery of benefits to society in the following areas: Disasters, Health, Energy, Climate, Agriculture, Ecosystems, Biodiversity, Water and Weather. The buoy array developed by IOMICS becomes a part of GEOSS.
