12:00-12:30

Organization of Breakout Sessions - Hinzman

12:30-13:30

Lunch

13:30-15:00

Five breakout sessions, two leaders for each (one coordinator, one scribe)

1)    Atmosphere - Cassano/Bromwich (CG Right Bay)

2)    Ocean-Ice-Atmosphere Boundary - Hunke/Serreze (CG Middle Bay)

3)    Ocean - Proshutinsky/Haidvogel (CG Left Bay)

4)    Terrestrial-Atmosphere Boundary - Liston/Lawrence (CG1 Room 3131)

5)    Terrestrial - Romanovsky/Euskirchen (CG1 Room 2655)

Questions to be addressed by each breakout session:

1)    What science questions exist for the arctic that are best answered with coupled regional models?

2)    What are the existing modeling and model validation efforts aimed towards answering these questions?

3)    What model and model validation projects are on the horizon aimed towards answering these questions?

4)    What arctic science questions cannot be answered with limited area regional coupled arctic models?

5)    What science questions are missing from existing efforts?

6)    What human systems are relevant to the physical systems being addressed?  Are there existing models for these human systems?

7)    What are reasonable boundaries on the ‘Arctic System’ for your area of research?

These questions should address physical, biogeochemical and biological systems

4. Community compass

   

16:00-16:30

Lessons learned from building community models - Vavrus/Lawrence/Hunke/Bailey/Holland (15 min talk, 15 min discussion)

16:30-17:30

Forum: Future direction - Hinzman

To the floor to answer these questions:

1)    Would arctic system science benefit from existing and planned efforts aligning into a cohesive community arctic system modeling effort?

2)    If not a single community end-to-end coupled model, is a coordinated, multi-model portfolio a good way to proceed with a network of individually maintained component models using the same coupling and archiving protocols?

3)    Are there questions not being addressed at present that can be addressed by either of these frameworks? 

4)    Could a community effort benefit model inter-comparison?

7. Exploration of future community collaboration

   

11:30-12:30

Forum: Potential for a community project - Walsh

To the floor to answer these questions:

1)    What are the most effective strategies for funding arctic system modeling activities to answer key science questions listed yesterday?

2)    Is a community pilot project a good way to proceed as a proof of concept for future coordinated regional coupled modeling, inter-comparison and validation?

If so:

a)     What subset of science questions from yesterday could a pilot-project easily address for early success?

b)    What component models and resources might be available for such a project?

c)     Should we proceed with a portfolio-of-models approach or an end-to-end model approach?

If not:

What other ways can the community coordinate regional coupled modeling efforts?

3)    What domains and boundaries should we define as the ‘Arctic System’ for community projects in light of yesterday’s breakout sessions?

(outcome added to a working report)

Organize after-lunch breakout sessions in light of the outcome of this discussion.

12:30-13:30

Lunch

Four breakout sessions, two leaders for each (one coordinator, one scribe)

1)    Coordination Strategy and Project management of a community effort:

a)     What is the best way to coordinate community work?

b)    Is it appropriate to establish a coordination committee?

c)     Are CCSM-like working groups the best model to follow?

- Walsh/Cassano (CG Left Bay)

2)    Gauging model performance:

a)     Should a validation standard be established?

b)    If so, what measurements might be part of the standard?

c)     Can we suggest inter-comparison protocols?

- Bromwich/Proshutinsky (CG Center Bay)

3)    Coupling protocols – software and strategy

a)     Is it useful to create a coupling standard?

b)    Is the best approach to make a single coupler available for community collaboration?

- Maslowski/Stark (CG Right Bay)

4)    Community biogeochemical/ecological/economic system modules (Human dimension benchmarks)

a)     Can a few ecological/economic modules be made available to get quick success for community biological and economic modeling of the arctic?

b)    Would any of these modules feed back to the system?

- Elliot/Cherry (CG1 room 3131)
