Active Participation in Model Evaluation

• Workshops
• Joint with other working groups
• On a specific science topic
• With other modeling centers (e.g. GFDL)
• With other organizations/programs (e.g. CLIVAR)
• Diagnostics
• Focus on coupled processes and errors
• Generate large suite of climate variability
  diagnostics
• Post diagnostics to the web
