1. Inter-American Institute for Global Change Research Data and Information System IAI/DIS 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.”

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. 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 IAI framework

6. 1.Understanding Climate Change and Variability in the Americas 2.Comparative Studies of Ecosystem, Biodiversity, Land Use and Cover, and Water Resources in the Americas 3.Understanding Global Change Modulations of the Composition of the Atmosphere, Oceans and Fresh Waters 4.Understanding the Human Dimensions and Policy Implications of Global Change, Climate Variability and Land Use IAI SCIENTIFIC AGENDA

8. GEC deals with the Earth system “in toto”: Ecosphere + the human factor Ecosphere Human factor atmosphere cryosphere hydrosphere lithosphere biosphere anthroposphere human decisions and actions “Anthropocene” era

9. 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 Global change

10. 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

11. Sea-ice extent Monthly anomalies (millions of km 2 ) 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

12. 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

13. 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). What is IAI-DIS ? 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.

15. 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

17. 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
