Recommendations to NSF

Recommendations to NSF

• The US should support development of an Arctic
  System Model through an open call from US
  agencies. We recommend two five year funding
  cycles to ensure completion of a viable Arctic
  System Model.
• This model should be constructed in an end-to-end
  framework that enables dynamic coupling among all
  system components (a core code with complete
  package of ocean, sea and land ice, atmosphere,
  and land, as well as terrestrial and marine
  ecosystems).
• This model should be built around a common
  existing flux coupler.
• Longer term vision includes social systems,
  metagenomics.

Recommendations to NSF

• There should be a central support and diagnostics
  center for the activity, to feature an active
  visitor program and virtual international
  collaboratory.
• Facilitate a testbed for parameterizations from
  other programs.
• Coordinating efforts among observational programs
  and modeling efforts.
• Provide computational support and resources
• Extensive dedicated computer resources must be
  available.
• New parameterization requires new, focused data
  collection and process studies.
• ASM analyses depend upon existing observing
  systems and should guide development of new
  observational programs.
• Dedicated scientific and programmatic support.
• Community users would have responsibility for
  substituting their own component modules as
  desired.
• Empowered coordinating group with a strong
  leader.
• Follow the CCSM-like working group structure
  entraining international participants.
• Strive to be compatible with widely used coupling
  frameworks.
• Accelerate arctic nesting capabilities in global
  earth system models.

Recommendations to NSF

• Science driven pilot projects (conducted with a
  coupled system) for advancement of science and
  early successes
• Trajectory of Sea Ice
• Carbon flux changes
• Processes affecting Greenland melt.
• Coastal Vulnerability
• Atmospheric chemistry and composition
• Short-term affects of permafrost degradation
