Dear three (plus one),

I may have told you that I am contributing to a review paper on solar 
effects
with Peter Foukal and some other astronomers. Part of this involves 
comparing
MAGICC results with the paleo data. The results are quite interesting -- 
I will
send them to you when I have updated them to account for my request below.

I am sure my analysis is more comprehensive than anyone elses, but it 
still needs
some work. I have compared MAGICC with ALL paleo data sets. However,
I need to do this with data that are consistently low-pass filtered 
(with different
filters). To do this means I need the raw (annual) paleo time series. I 
do not
have all paleo data in this form. For example, some of the data that 
Phil and Mike
Mann have produced seem only available as (roughly) decadally-smoothed
data -- and Crowley has put somethong like an 11-year running mean (a crappy
filter) through his data. I think I can get the raw Crowley data. Can 
any of you
send me the Mann and Jones  (NH, SH, GL) and Jones and Mann data please --
as soon as possible, as ASCII.

My analyses so far have involved 1000s of model runs and statistical 
analyses.
What goes into the Foukal et al. paper will just touch the surface of 
these results,
since the paper is oriented towards the astronomical side. Caspar Ammann 
and
I will write up a more complete paper on the climate side. You might 
like to be
involved in this (Sarah too). We have various runs with paleo-CSM to 
cover too,
and these are quite interesting. MAGICC fits the AOGCM very well.

I am planning to come to CRU in early August. I would like to come 
sooner, but
it is just not possible. I will tell you dates when I know them.

Best wishes,
Tom.
