The project will establish water data sharing and exchange policies and data management strategies in the Asian region that will enable (1) integrated data access and transfer among Asia national research groups and between these groups and international organizations such as WMO and UNESCO, and (2) effective transfer of observation information and scientific knowledge to water resources policy- and decision-making groups. These capabilities will aim toward building up national/regional capacity to conduct water cycle research in a more efficient, coordinated manner and to exploit research results for solving societal issues associated with the water cycle features in Asia . In this way the IIDATA effort will contribute to APN activities in support of the Global Earth Observation System of Systems (GEOSS) especially within the context of GEOSS Work Packet Two Year (2006-2007) Target #042.
