1. WDC for Meteorology, Asheville An Introduction NOAA/Roshydromet Data Exchange Workshop 30-November to 1-December 2011Asheville, North Carolina

2. Agenda • Web Page • ICSU World Data System Member as of September 2011 • Framework • Global Observing Systems Information Center (GOSIC) • Relationship to Global Observing Activities • Relationship to Regional Data Management Activities

3. WDC Meteorology Web Page http://www.ncdc.noaa.gov/oa/wdc/ Quick Access to Data is Key – By Theme, Region, or Country e-mail contact:wdcamet@noaa.gov

4. WDC Meteorology Web Page http://www.ncdc.noaa.gov/oa/wdc/ • Quick Access to Data is Key – By Theme, Region, or Country • Access to Data • 1961-90 Normals Data for many nations • World Weather Records • Projects such as the International Best Tracks Archive for Data Stewardship (IBTrACS) • Want to expand to include linkages to electronic Meteorological publications from various nations • e-mail contact:wdcamet@noaa.gov

5. WDC for Meteorology, Asheville Framework Global and Regional Observing Programs GEOSS, GCOS IPY, etc. Global Observing System Information Center (GOSIC) NOAA/National Climatic Data Center WDC Meteorology, Asheville Regional Data Centers (e.g., APDRC and IDEA)

6. The GOSIC Portal can be accessed at: http:// GOSIC.ORG

7. The GOSIC: • was established in 1997 by the GCOS Joint Data and Information Management Panel (JDIMP) • was developed at the University of Delaware • was twice reviewed by independent panels (01/03) • has been operational since 2007 at NOAA’s National Climatic Data Center (NCDC)

8. What does GOSIC offer: • Users can find data and information about the GCOS, GOOS and GTOS and subsystems without having to navigate the hundreds of complex and vastly different web sites of the myriad of organizations in these global observing systems • Allows users to determine the type and quality of the data through documentation provided by the participating data centers • Provides access to data and data download regardless of data format

9. What does GOSIC offer (continued): • Provides quick and user-friendly cross-system access to data and information • Provides a comprehensive inventory of datasets • Links and information are kept up to date and are quality controlled with input from the secretariats and the World Data Centers • Eliminates redundancy

10. Provides documentation of datasets and program elements: • Observing Requirements • Planning Documents • Data Management Plans • Publications • Value added products: • Data Matrices • Data Flow Diagrams • Provides several search mechanisms What does GOSIC offer (continued):

11. The GOSIC cooperates with NASA’s Global Change Master Directory (GCMD) to provide metadata for the global observing systems datasets. • Users can access metadata via a portal on the GCMD

12. The Essential Climate Variables (ECV) Data Access Matrix: • provides access to data, metadata and information for 49 ECVs; this was updated on 15-Sep-2010 to match IP-10 [GCOS-138] • ECVs are required to support the work of the United Nations Framework Convention on Climate Change (UNFCCC) and the Intergovernmental Panel on Climate Change (IPCC). • all ECVs are technically and economically feasible for systematic observation. It is these variables for which international exchange is required for both current and historical observations.

13. The Essential Climate Variables (ECV) Data Access Matrix (continued): • give access to authoritative datasets • datasets have been identified by experts developing standards for the ECVs • available at http://gosic.org/ios/MATRICES/ECV/ECV-matrix.htm

15. The GOSIC’s overriding goal is to best serve the data access needs of all of GCOS (atmosphere, ocean, and terrestrial), and as such, we believe that serves as a data portal for GCOS. That in no means that it is the sole route to such data, however, the GOSIC has the potential to serve as a unifying facility for GCOS that reaches across the various observing domains (e.g., atmosphere, ocean, terrestrial) and gets GCOS out of the mode of being perceived as being only about the GSN and GUAN.  The GOSIC facility also helps GCOS reach out to the greater GEOSS community as well by having established linkages in the GEOSS Data Registry as well as membership on the GEO Data Architecture team dealing with data integration and analysis

21. Directions of joint studies • Joint monthly update of GDCND with a large suite (up to 900) of the CIS daily data • Participation in the data feed for Global Reanalysis update (Compo et al. 2010) • Monthly exchange of the local and regional GTS fluxes of synoptic information • Data exchange and joint studies of snow cover properties that are not easily available from the satellites • Continuation of joint assessments of bias-corrected precipitation in high latitudes
