In 2004, the Ionosphere Research Room of the Wuhan Institute of Physics and Mathematics, Chinese Academy of Sciences was also integrated into the IGGCAS. Since this integration, IGGCAS has become one of the most important and well-known geoscience research institutions in China. IGGCAS is strategically positioned to "establish a brand new international research center with the qualities of "theoretical innovation, technical development, achievement transformation and sci-education integration”, aiming at global technology front, national vital demands, national economic fields, and the main direction of solid Earth sciences. Original breakthroughs have been made in research on global Earth sciences to develop the theory of Earth sciences. IGGCAS’s focuses are major scientific issues in the fields of national resources, energy and environment, so as to support national strategic needs and serve economic and social development.
