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

NACP Data Policy: Key Elements1. Definition of NACP Data2. Data Sharing
Integrating data for NACP requires a data policy that provides open access to data in a timely manner
3. Giving Credit to Data Collectors4. Protecting the Rights of Students5. Data Management based on standard metadata and
open source software6. Data Archive7. Sharing and archiving models (source code)
8. Acknowledging NACP9. Resolving Conflicts
NACP Investigator Meeting 2007

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:

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 Tasks1. Establish specific data management needs of
NACP modelers and synthesis groups and coordinate with other thematic data centers;
2. Prepare and distribute model input data; 3. Provide data management support for model
outputs; 4. Provide tools for accessing, subsetting and
visualization; 5. Provide observation data packages to
evaluate model output; and 6. Support synthesis activities, including data
support for workshops

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

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
