    Reinhard et al,
       Attached is the series that was used in the IPCC Chapter (i.e Box 3.6 Figure 2).
    To get those numbers you just average months 6-8 from each of the lines. The 13th
    number is the annual average.
      Some proxy series illustrating the issue would be fine. I just think the model
    simulations are too much I'd include proxy series that have annual timescale resolution,
    so grape harvests fine. Where the smooth transition between the proxy and the
    instrumental issues goes is debateable. It could be here, but only if it were for
    the documentary type data (i.e. not trees).
       Happy not to get a revised draft until next week. I'm in Zurich some of next
    week at a meeting Rob Allan is organizing.

    Cheers
    Phil

     Dear all,

     Thanks for your recent comments everybody sent me so far, thanks Phil for offering to
     produce the final version of the introduction. In the mean time I have re-written it
     myself a little and also the whole text has grown. I hope to have it ready by Monday
     latest, and I think it is wise not to send you another piece right now but to rather
     pose the finished draft to your disposal, remarks etc. then. I have already included
     most of your remarks and corrections you sent so far.

     Just one thing, Phil: Yes I have planned to use the CE-mean longterm temperature series
     (it is the one from a box in your chapter of the IPCC-WG1 report I suppose?). Can You
     send me the data, just to present it in common style.

     And one question right now: I still think that at least showing some proxy series to
     illustrate what I have written in one short paragraph in the introduction would be good
     to visualise what this warm bias possibly is about. Of course we must make it clear that
     we have not used proxy information for adjusting.
     As I see already from  the length of the text I have so far, the proxy section must
     really be kept short in this paper, and I hope that you will include them in a broader
     sense in your follow up paper? And for this I would also suggest to include more than we
     produced in ALP-IMP, but also some of the mentioned things from lakes, grape harvests?

     I hope that You have in mind such things in order to advertise the idea of an early
     instrumental period is one of a smooth transition from proxy based reconstructions
     (prior to 1750) to pure instrumental (after 1860). I planned to do this at the end of
     this paper, but maybe it is better to postpone it for the following one.

     Best regards

     Reinhard
