1 Data Sharing Background in China Data Sharing Network of Earth System Science

Scientific Data Sharing Program (SDSP) in China • SDSP was launched by MOST in the beginning of 2002 • According to its plan, there will be 40 national data centers, cover 300 master databases, in 6 fields at the end of 2020. Framework of China SDSP

DSNESS • One of 9 Pilot Projects in SDSP • Long term project, 2002- • Host by Institute of Geographic Sciences and Natural Resources Research, CAS • Lead Scientist: Prof. Sun Jiulin, IGSNRR • http://www.geodata.cn Data Sharing Network of Earth System Science

National Science & Technology Infrastructure (NSTI) • NSTI was launched in 2004, 2 years later after SDSP, supported by MOST, State Development and Reform Commission, Ministry of Education, Ministry of Finance of China • Data sharing is the core of NSTI SDSP is one of important parts in NSTI DSNESS also is one of projects in NSTI • Data sharing portal: www.escience.gov.cn Data Sharing Network of Earth System Science
