1. DATA COLLECTION, STORAGE AND EXCHANGE UNDER THE AUSPICES OF THE WORLD METEOROLOGICAL ORGANIZATION Geoff Love vice president, WMO’s Commission for Basic Systems and Deputy Director, Commonwealth Bureau of Meteorology

2. Theme for the Workshop Data access and integration: Global and regional initiatives and client perspectives. - who are the key players? - key technical, policy and other issues? - addressing the issues? - directions to take? - Are we doing enough?

3. Two parts to this talk: A review of the WMO’s data collection, storage and exchange arrangements Comment on the issues identified by the Workshop convenors From a global perspective

4. The World Weather Watch (WWW) Established in 1963 To meet the need for standardised meteorological and related data of sufficient density to meet the operational and scientific needs of the World’s meteorological community Operated cooperatively by the 185 Members of WMO

5. WWW Operational Arrangements The WWW is built around 3 systems: The Global Observing System (GOS); The Global Telecommunication System (GTS); and, The Global Data-Processing System (GDPS).

6. GOS: (surface meteorological parameters)

7. GOS: (Upper air data from radiosondes)

8. GOS: (Aircraft reports received at the ECMWF (in UK))

9. GOS: (Space-based observations - TOVS data at ECMWF)

10. GTS: (Configuration of major links)

11. GDPS: (Location of World and regional centres)

12. Data Exchange Policy Resolution 40 of the WMO’s 12th Congress: As a fundamental principle of the WMO, and in consonance with expanding requirements for its scientific and technical expertise, the WMO commits itself to broadening and enhancing the free and unrestricted international exchange of meteorological and related data and products

13. Who are the key players? The National Meteorological and Hydrological Services; The WMO; Data suppliers (satellite operators, ship operators, aircraft operators, etc); Data and information users (the list is very large!).

14. Key technical, policy and other issues for data providers and end-users? Resources; Coordinating requirements; Agreement on technological initiatives (including rate of up-take); Stable, long-term system management

15. Addressing the issues ? Developing and promoting the role of the WMO; Re-structure of CBS; Broadening of terms of reference; Inclusion of a broader base of expertise; Adoption of more broadly-based standards

16. Moving in the right direction? Rapid upgrade of core GTS technologies; Globally accessible distributed databases; Better links to data supplier and data user communities; Work, through cooperation, to avoid systems which duplicate existing functionality.

17. Conclusions Meteorology has a “killer application”, not necessarily compatible with SDI; Paths are possibly converging? Convergence through standards? Data access policy will be key, systems may not be enough! We want to work with you.
