DESCRIPTION
Summary of the Day. • Need for integrated physical, biological, social science data sets “Incentive structures to encourage inter-d work” “Identification of relations between bio and socio-ec components and climate indicators” - PowerPoint PPT PresentationTRANSCRIPT
Summary of the Day• From Breakout reports, vision talks, Q&A, informal
discussions…repeated statements on
• Need for integrated physical, biological, social science data sets
“Incentive structures to encourage inter-d work”
“Identification of relations between bio and socio-ec
components and climate indicators”
“To integrate atmospheric/ocean/biological/socio-ec data
faces fundamental challenges in data comparability.”
• Need for frameworks to allow for data harmonization
“If you build a data platform, the data will come”
“…lots of time/money to force data into common formats…”
• Need for data searching across disparate sources
“..no mechanisms in place to inventory what’s out there”
“..so many places to get these data…that it is confusing”
• Community-model should not = monopoly
“Community-type models (CCSM-style)”
• Downscaling global model data / upscaling process data
“…create iterative process among modelers, providers, idea generators”
• Consider near-real time horizon
• Statements (continued)

“ARCTIC SYSTEM FRAMEWORK”
• High resolution• Modules to accommodate advances in disciplinary knowledge
• Near real time…like NWP (snapshot of current state)
• Mid-term (push forecast capability over yrs/decades)
• Century-scale (test scenarios and impacts of strategic policy decisions)
CSDMS-Community Surface Dynamics Modeling System: New NSF National Center
@UCBoulder (NSF Cyberinfrastructure Directorate)
Module-based software architecture to foster community model development and synthesis studies
Such Frameworks Already Exist and Could Be Capitalized Upon
Proposed Charge
AM:
• What ideal framework / data / modeling system could we build as a community w/o constraint?
TheWhat
PM:
• What gaps, challenges, obstacles prevent us from attaining the vision now?…..what new research investments should be made?
TheHow
Products
IT Toolbox, Flux Couplers
Process Study, Monitoring Data
Simulation Modules

ARCSS Synthesis Workshop: New Perspectives through Data Discovery and Modeling
2-4 April 2007, Bell Harbor Center, Seattle WA
GOAL: Bring together data provider & data user communities to identify innovative approaches on data management and assimilation, recent developments in technology, and modeling that will advance arctic system synthesis
-more than IT, archiving, metadata standards, data management alone
-process as much as products: identify challenges holding us back, but also success stories & promising new approaches
-ways to structure the way we do business to identify and nurture advances not yet identified
-advice can we give NSF on investments in data and modeling-rich synthesis?
