Arctic System Modeling Workshop II: Science Planning (2008)

May 19-21, 2008
NCAR Center Green
Boulder, Colorado

Overview

Meeting Summary

The University of Alaska Fairbanks International Arctic Research Center held a community workshop on the implementation of a community limited area Arctic System Model or Portfolio of Models in Boulder, Colorado, May 19-21, 2008. This workshop addressed a growing need for numerical tools to downscale information from global models to the temporal and spatial resolution of in-situ and satellite measurements and scales appropriate for planning for economic and social change in the Arctic. The workshop was announced in two issues of EOS (PDF), the CliC Newsletter (PDF) and ArcticInfo following an initial announcement (PDF) of the meeting at the 2007 American Geophysical Union Fall meeting. A list of workshop participants is available below.

The aim of the workshop was to discuss viable approaches for development of a limited area Community Arctic System Model. Presentations and working documents from the meeting can be downloaded below. Meeting outcomes, downloads and links to other ASM meetings are also available below. For further information on the science content of the meeting, please email Andrew Roberts (arobertsarsc [dot] edu). Also see websites for the ASM I and ASM III meetings.

  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:

    • What subset of science questions from yesterday could a pilot-project easily address for early success?
    • What component models and resources might be available for such a project?
    • 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?
    • What domains and boundaries should we define as the ‘Arctic System’ for community projects in light of yesterday’s breakout sessions?
