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

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

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

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_P

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)

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.

11
MAST-DC Tasks

1. 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

• Current services from MAST-DC
• Provided jointly with NASAs 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

NACP Data ManagementConcluding thoughts (1 of 2)
Challenge Providing effective data management
to meet NACP goals in the absence of Data Central

• 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

16
NACP Data ManagementConcluding 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

Ocean Data Management Activities

• OCCC and OCB data served by Woods Hole
• Carbon biogeochemistry data (primarily pCO2)
  served by ORNL

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

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

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
