cc: Sarah Raper date: Mon, 13 Jun 2005 16:16:00 -0600 from: Tom Wigley subject: paleo data to: Phil Jones , Keith Briffa , Tim Osborn 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.
