Mission

The aim of the Water Cycle Data Integrator (WCI) unit is to promote research activities, education, and operational implementation of the data integration approach for addressing water cycle related issues. Integration of Earth observation data with local measurements and information on water cycle and water-related fields including climate, food, health, energy, biodiversity as well as disasters and economics is essential for holistic understanding of water cycle variability changes, improving capability to predict them, quantitatively evaluate their impact on society, and propose adequate adaptation measures. Such data integration function has been enabled by the Data Integration and Analysis System (DIAS), which was launched in 2006 at the University of Tokyo and has been progressing towards provision of operational services. The WCI unit pursues maximum exploitation of DIAS as a data information infrastructure for generating public benefits at both domestic and international scene.

Create scientific knowledge

Creating new, value-added scientific knowledge through integration and analysis of "big data".

Education

Systematic education using the scientific knowledge acquired through data integration and information fusion.

Generate public benefits

Contributing to global problem solving by providing pertinent and actionable information for decision-makers.

Research

By integrating data from satellite- and ground-based Earth observations and outputs from climate and numerical weather prediction models with geographical and socio-economic information, we investigate water cycle variations and its possible future changes and provide vital information for integrated water resources management practices including efficient water usage as well as mitigation of water-related disasters. Using DIAS, we create a data integration platform to combine hydrological models with data and models from various fields such as climate, agriculture, biodiversity, urban planning, disasters, and economics. Using river basins as units of the land water cycle system and through collaboration with governments and local communities, we carry out and demonstrate pilot studies that provide sound information for solutions.

Expected Effect

Through cooperation and coordination among national and international research groups and institutes, we will stimulate data and information integration for the water cycle related fields and promote the use of DIAS for practical and operational applications for supporting decision making and planning. We also aim to initiate cooperation with various stakeholders by advancing efforts to combine analysis methods, data assimilation techniques, and prediction models that extend beyond any one field. By these actions, we will contribute to generation of scientific knowledge, which will help us to discover the wisdom needed for attaining the humanistic goal of sustainable development. At the same time, we hope to foster creation of an environment, where such knowledge and wisdom can be widely shared.
