Try to keep your list short; perhaps several small issues can be dealt with under a bigger issue. Ideas that come to my mind are (please help me frame these better if you agree that they are issues): a) EMICS and GCMs - how to present in a balanced and consistent manner? b) model evaluation and implications for models used in Chapter 10 (e.g., does the IPCC put too much weight on models that appear to evaluate less well?) c) are discussions of what is known and not known about hypothesized climate forcing (e.g., solar) consistent across chapters? What else? It appears that I need to send Martin feedback soon, so please send your input to me asap. CC to the others unless there is a reason not to, but everything should go to Eystein too. thanks, Peck X-Sieve: CMU Sieve 2.2 Date: Mon, 18 Apr 2005 19:05:34 -0600 To: stocker@climate.unibe.ch, jto@u.arizona.edu From: Martin Manning Subject: WG1 LA2 meeting - Overlap cluster D Cc: Susan.Solomon@noaa.gov, ipcc-wg1@al.noaa.gov Dear Tom and Peck Please find attached our current program for the second Lead Author meeting on May 10 - 12. We will shortly be sending out some more details on the plans for the meeting and in particular would like to clarify what needs to be done in the Overlap Cluster meetings shown in the program on Wednesday 11th. This is to ask if you would be prepared to jointly co-chair the session on Overlap Cluster D dealing with "Consistency in coverage of modelling on various time scales" and which will involve discussion among chapters 6, 8, 10 and possibly also 4, 7, 9 and 11. The attached program lists, on the last page, overlap / consistency areas that have been mentioned in the ZOD. We would really be most grateful for your assistance in this, and if you agree, we would like to ask that you each to specify what in your view would be the 2 or 3 most important issues to resolve during the overlap cluster session. We will then use your input to draw up a specific agenda and circulate agendas for all overlap clusters to all CLAs prior to the meeting. We hope in this way that we can reach a shared understanding of the most important overlap and consistency issues and the corresponding key decisions that will have to be made in Beijing. I would be grateful if you could let me know whether you are able to help us with this by Wednesday 20th.
