cc: "'Phil Jones'" , "'Gabi Hegerl'" date: Mon, 26 Nov 2007 17:22:14 +0000 from: Keith Briffa subject: RE: Collaboration to: , Hi Simon (and others) I have to say that this is what I had envisaged was "our" plan , following our earlier discussions with Simon and Philip Brohan. I do think this is a good idea , with the special focus on the period of the early instrumental data , perhaps even more than on the earlier data. The project could include more concentration on the identification and separation of "natural" dynamics-related climate changes from anthropogenically- forced changes , using multiple GCM experiments and possibly EMIC runs. This would also require a much more elaborate scheme of exploring different proxy , instrumental , and joint proxy plus instrumental reconstructions and errors (my preference would be for a "European and US window ") , based on reanalyses and critical review of the existing reconstructions and repeat reconstruction exercises where we can better constrain the differences in method . However, how much of this is now foreseen in your current application I do not know. Either way, you know that a joint , multi-institutional proposal is OK with me. Hope all is going well for you and that the family are well Keith At 11:54 25/11/2007, Simon Tett wrote: > >Hi Tim (With Keith added to the CC list).
