  1. Inter-American Institute for Global Change Research Data and Information System IAI/DIS Inter American Workshop on Environmental Data Access 3-6 March 2004, Campinas, Brazil

  2. Global Change “Changes in the global environment (including alterations in the climate, land productivity, oceans or other water resources, atmospheric chemistry, and ecological systems) that may alter the capacity of the earth to sustain life.”

  3. INTER-AMERICAN INSTITUTE FOR GLOBAL CHANGE RESEARCH Signatory and Ratifying Countries (Agreement entered into force: March 11, 1994) 1. Argentina 16. Perú 2. Bolivia 17. Estados Unidos 3. Brasil 18. Uruguay 4. Canadá 19. Venezuela 5. Chile 6. Colombia 7. Costa Rica 8. Cuba 9. República Dominicana 10. Ecuador 11. Guatemala 12. Jamaica 13. México 14. Panamá 15. Paraguay

  4. IAI Main Goals Conduct and promote research on global change and their interaction with human activities [Agreement Art.II a) to e), g), h)] Improve public awareness and serve as an effective interface between science and the governmental policy process [Agreement Art II, f)]

  5. IAI framework Constituent bodies: CoP, EC, SAC, Directorate Programmatic framework: Science agenda Structure: Distributed network of national and international research and policy institutions Activities: Science program and funded research, CRN, Grants Training and education Support to workshops, conferences and seminars Surveys (HD of GC) Data and Information System (DIS) Newsletter Listserver

  6. IAI SCIENTIFIC AGENDA • Understanding Climate Change and Variability in the Americas  • Comparative Studies of Ecosystem, Biodiversity, Land Use and Cover, and Water Resources in the Americas • Understanding Global Change Modulations of the Composition of the Atmosphere, Oceans and Fresh Waters • Understanding the Human Dimensions and Policy Implications of Global Change, Climate Variability and Land Use

  8. Global change • Involve a large and wide spectrum of issues • Multifaceted • Inter-, Intra- & trans-disciplinary (cross-cutting) • Multi scales (time & space) • Required interactions and dialogue between: • - Hard sciences (Earth System Science ESS) • -- well established methodologies • - Soft sciences (HD, socio-economic) • -- no standard methodologies

  9. Global Environmental Change Data • Needed for • SCIENCE • MANAGEMENT, POLICY , DECISION MAKING • Establishment of open and on-going processes identifying data and information requirements from research scientists and managers and policy makers may be of great help

  10. Sea-ice extent Monthly anomalies (millions of km2) of Arctic and Antarctic sea-ice extent for the period 1973-2002, derived from satellite passive microwave sounder data (Source: HadlSST1 data set, Hadley Centre, UK Met Office) Trend : - 2.8 % per decade

  11. Antarctic sea ice decline since the 50s (M.A.J. Curran et all., Science, Vol.302, 14 Nov. 2003) MSA: Methanesulphonic acid SIE: Sea ice extent for the 80E to 180E sector (satellite derived) Trend: 20% decline in SIE since about 1950

  12. What is IAI-DIS ? • an Internet based system dedicated to the dissemination of scientific information produced by the IAI projects, following a pre-defined standard (Z3950), as well as to ease the exchange of that information between institutions/organizations. It was developed by CIESIN (Center for International Earth Science Information Network). • IAI-DIS main objectives • Disseminate global change research information produced by the IAI, and other affiliated institutions, and • Contribute for the standardization and exchange of scientific data between different institutions.

  13. National Node PO PO LBA-DIS Ciesin SEDAC IAI-DIS Coordinator Node PO: Participating organizations

  14. Main features of the IAI-DIS system: • WEB access and user-friendly interface; • Integrated Search and Retrieval modules; and • Two levels of METADATA ( “information about data” – a short, organized and searchable form of documentation used to find data). • What IS NOT IAI-DIS • It is not a statistical system; and • It is not a tool to make automatic comparisons between actual data

  15. Drawbacks • System up and running for 4 years – some components obsolete • Present system is not easy for a layman user • Future actions • “Aggiornamento” - update of the system • - increase the “user-friendliness” • Creation of a distributed network of GEC DIS in the Americas
