  4. NACP Data Management Planning Activities(Thornton and Cook, Co-chairs) • January 2005 Workshop • Multi-agency, international workshop to define NACP data system • Report available on www.nacarbon.org • NACP Data Systems Task Force (formed May 2005) • Subgroup of Science Steering Group • Formed to describe the requirements for an NACP Data System and develop an NACP Data Policy NACP Investigator Meeting 2007

  6. Background: NACP Data Policy • Recommendation from NACP Data Workshop Report (January 2005) • NACP should develop a data policy • CCIWG and SSG should develop effective means for implementing the data policy • NACP Data Policy • Based on international and national data policies, e.g., • IGBP • Climate Change Science Program • Large-Scale Biosphere Atmosphere Experiment in Amazonia • AmeriFlux • For US Investigations NACP Investigator Meeting 2007

  7. NACP Data Policy: Key Elements • Definition of NACP Data • Data Sharing • Integrating data for NACP requires a data policy that provides open access to data in a timely manner • Giving Credit to Data Collectors • Protecting the Rights of Students • Data Management based on standard metadata and open source software • Data Archive • Sharing and archiving models (source code) • Acknowledging NACP • Resolving Conflicts NACP Investigator Meeting 2007

  8. NACP Data Policy: Next Steps • Status: NACP Data Policy approved by SSG and CCIWG as a draft for review by NACP Investigators • Provide feedback / comments to Peter Thornton and Bob Cook by February 9 • Review version is available on NACP Web Site on the “Documents” page: http://www.nacarbon.org/nacp/documents/NACP_Data_Policy_200611_ssg.pdf NACP Investigator Meeting 2007

  9. NACP: Data System Components • “Data Central” not funded • Project Profiles and links to data at NACP Web Site (www.nacarbon.org) • NASA solicited for “Thematic Data Center for Modeling and Synthesis” • Modeling and Synthesis Thematic Data Center (MAST-DC) was selected • Bob Cook, Mac Post, Bruce Wilson (ORNL), and Peter Thornton (NCAR) (investigators) NACP Investigator Meeting 2007

  10. Goals Of MAST-DC • Provide data management services to NACP investigators and agencies performing modeling and synthesis activities • Free modelers and those doing the synthesis and integration from having to perform data management functions. • Based on NACP requirements established, MAST-DC will provide data products and services in a central location, in consistent and uniform grids, with common and co-registered spatial projection, in easily converted formats. NACP Investigator Meeting 2007

  11. MAST-DC Tasks • Establish specific data management needs of NACP modelers and synthesis groups and coordinate with other thematic data centers; • Prepare and distribute model input data; • Provide data management support for model outputs; • Provide tools for accessing, subsetting and visualization; • Provide observation data packages to evaluate model output; and • Support synthesis activities, including data support for workshops NACP Investigator Meeting 2007

  12. NACP User Community (and others) Digital Elevation ModelSRTM Soils – CONUS+ Land Cover – MODIS • MAST-DC Web Page • Link to NACP Project • Link to Thematic Centers • Index of MAST-DC Data (Mercury) • OPeNDAP access to • MAST-DC Data Metadata Registry Historical Land UseLEDAPS • Services • Data Access • Subsetting • WMS/WCS Weather / Climate -DAYMET LAI / fPAR MODIS4NACP Nitrogen – Dentener Observation Data Packages to evaluate model results Bottom-up Model Output Coastal Ocean Investigator Data Remote Sensing Atmos.

  13. Current services from MAST-DC • Provided jointly with NASA’s ORNL DAAC (Distributed Active Archive Center) • Survey on spatial data requirements (ends on Feb. 1) • Clearinghouse of background data for NACP • WebGIS with background layers and links to field data • Subsetting tool for remote sensing products (MODIS Land Products) • Links to existing data products and thematic data centers Web Site: nacp.ornl.gov/mast-dc/ NACP Investigator Meeting 2007

  15. NACP Data Management:Concluding thoughts (1 of 2) • Leverage as much as possible from thematic data centers (action: CCIWG and SSG) • NACP needs to improve coordination with existing thematic data centers • Data sharing strategies to facilitate the exchange of data / information from many data sources (action: Investigators) • Creative solutions from investigators Challenge: Providing effective data management to meet NACP goals in the absence of Data Central NACP Investigator Meeting 2007

  16. NACP Data Management:Concluding thoughts (2 of 2) • Coordinate data needs of a highly diverse collection of investigations (action: Investigators) • Identify data you will produce and share • Identify data you expect others to provide • Identify data gaps (data you need to complete your analysis) • Identify data products required for synthesis and modeling • Key actions for each of the breakout groups • By February 9… • Provide comments / feedback on the NACP Data Policy to Peter Thornton and Bob Cook NACP Investigator Meeting 2007

  18. Ocean Data Management Activities • OCCC and OCB data served by Woods Hole • Carbon biogeochemistry data (primarily pCO2) served by ORNL Data from ships of opportunity (Underway data) Buoy / mooring data NACP Investigator Meeting 2007 Photos from Alex Kozyr, ORNL

  19. Data Central: High priority functions • Coordinate with NACP-related thematic data centers • Define metadata standards • Establish and maintain a metadata index of NACP-relevant data holdings across multiple Thematic Data Centers, including index of data held locally by projects/PIs • Coordinate with NACP Office to link the dataset metadata index with the project metadata index generated and maintained by the NACP Office • Provide metadata entry tools for investigators who are not working directly with a thematic data center NACP Investigator Meeting 2007

  20. Data Central: High priority functions Functions originally envisioned for Data Central that might be met by the thematic data centers • Data versioning system, with subscription and update services • PI-managed access control (following NACP Data Policy) to versions of data • Machine access to data holdings (OpenDAP servers) • Subsetting and GIS data services NACP Investigator Meeting 2007

  21. Data Coordination • NACP is an ambitious highly integrated interdisciplinary research program, designed to use observations on land, sea, air, and from space with models to understand carbon cycle • Data will come from a wide array of sources and be used for a large number of purposes • Extensive coordination between those making the observations and modelers is critical NACP Investigator Meeting 2007
