Necessary Advances in Prediction

• Model Improvements - reducing systematic errors
  (WGMD)
• Better Constraining Initial Conditions (GSOP)
• Do the Coupled Assimilation Problem! (GSOP)

Issues and Developments

• Controlled Experimental setting provision of
  data sets and uncertainties.
• Uncertainty measures are required
• Publications 4 CWP several other in
  preparation or published already.
• EasyInit provision of ocean syntheses to coupled
  modeling community.
