Chair:                         Ted Shepherd

Rapporteur:               Hideharu Akiyoshi

 

What sort of model configuration the CCM groups plan to use for the next round of assessments, e.g. coupled to ocean, with tropospheric chemistry, changes in model configuration compared to WMO 2006, what time period, how much capacity for different scenarios, etc. ?

 

Groups will be asked to send in 2-3 slides in advance, to be assembled into a single presentation along with a set of questions. Preferably and if they have a representative there, then someone from the group should stand up and present that group's slides.
