International Research Cluster is a research promotion system established in parallel with each International Joint Graduate Program responsible for international joint education. It aims to become an international center for each research area and promote international joint research. The International Research Cluster in Earth and Environmental Sciences collaborates in different fields such as science and engineering and internationally, and is characterized by the world’s most accurate observation technology, unexplored extreme experimental technology, and world’s highest resolution analysis. While strongly promoting the development of methods and leading the world, we aim to clarify the origin and future of earth-planetary changes and global environmental changes by deepening and integrating research on various sciences.
