Workshop #9, June 6-7, 2005

Framework Topics

The focus of the workshop will be the continued analysis of the 1948-2004 simulations and validation. The workshop objective is to recommend improvements in existing model parameterizations. The workshop recommendations are to be implemented in new simulations of the 1948-2004 period to be carried out during the second-half of calendar year 2005.

Day 1 of the workshop will involve a comprehensive discussion of results from the Coordinated 1948-2004 experiment.

Day 2 will be dedicated to a discussion of various topics:

• model calibration and validation approach;
• model improvement plan;
• collaboration and coordination of our activity with other MIPs;
• some internal problems including:
  • project coordination,
  • funding opportunities,
  • research themes,
  • publications.
