One of the most difficult problems APN scientists are facing now is the lack of Earth Observations (EO) data and data usage experience. Global Change Research (GCR) mostly depends on multi-disciplinary knowledge and multi-source EO data and scientists in this field mostly have to base their model research and system development on just a few given EO data sets. The next generation of EO data and information infrastructure are focusing on multi-agency collaboration technologies. This provides users with a new way to both utilize and organize their global change studies. As the leading international organization promoting interoperability and sharing of multi-source EO data, The Working Group of Information Service and Systems in the Committee of Earth Observation Satellites (CEOS/WGISS) has a lot of experience and knowledge on this topic. This project brought the experience and knowledge from CEOS/WGISS to the GCR scientists in the APN region, especially in Mongolia, to demonstrate how to access and use the next generation EO information technology, and to find appropriate approaches to develop their global change models based on this new EO capability and support. This project was supported by and collaborated with the United Nations Global Alliance for ICT and Development (UNGAID), ICSU’s Committee on Data for Science and Technology (ICSU/CODATA), as well as GEOSS. A series of workshops have been taken in both China and Mongolia, which collected dozen of local scientists to participant and share the experience from leading experts from USA, Europe and Asia local. The expected outputs listed in the proposal have been reached in this stage and a lot of new opportunities have been addressed from the discussion.
