Hi Friends - this email is for all Chap 6 LA's who work with 
generating and using paleo data.

Section 6.2.2 (Methods - Observations) has turned out to be a bit 
more complicated than at first pass. Jean-Claude has taken a stab, 
and his effort (appreciated) makes it clear that we have a job still 
to do before the ZOD, as well as after. We can postpone most of the 
detailed effort until after the ZOD, but what we need is a good, 
chapter relevant and up-to-date methods section for the ZOD. Since 
Jean-Claude is a paleoceanographer, that part of his text is in good 
shape. However, we need to balance it out. So, if you are a data 
person, pls answer (respond to both Peck and Eystein):

1. do you have time to help Jean-Claude draft a really good 1 page 
section? If yes, Eystein can send Jean-Claude's prose right away (or 
I can if he doesn't do it first).

2. what data types are used in our section?

3. what methods (i.e., chronological, proxy measurement, calibration, 
analysis, etc.) need to be mentioned?

4. what methods of data generation, calibration or analysis are new 
or significantly improved since the time of TAR?

5. what are the key references (especially post-2000) references for 
#'s 2, 3 and 4 above?

The job of the section 6.2.2 writing team is to produce a short (1 
page final IPCC, or 2 page single spaced draft) section that gives a 
balanced overview of the data-related methods on which our chapter is 
based. As Jean-Claude notes, it needs to start with some 
introduction/motivation, and then it needs to turn to time control, 
and then types of data - both forcing and response. It should also 
briefly discuss analysis breakthroughs. I'm guessing Keith would be a 
huge help here, once he gets his last 2000 years section done. 
Fortunat is also needed to ensure we get his part of the picture 
painted well.

So, looking for some heros. EVERYONE, please send in the answers to the above.

Thanks! Peck
