date: Mon Jul 12 14:14:17 2004 from: Keith Briffa subject: Re: Tree-ring plots to: Michael Schulz Michael I am attaching a few powerpoint slides - showing a current version of the Swedish series and the Finnish series . These will change very slightly (to reflect different long-timescale preservation) but the basic pattern of variability will not change. The first two Figures are annual values with bootstrapped 95% percent confidence limits. The final Figure is the overlay of the two with confidence bands removed for clarity. Note that the differences in the series often reflect low confidence in one or both series, The differences around the Medieval time and the "Little Ice Age" (!) are less in our modified data (still being worked on) but still maintain. I can produce numbers soon when we know were we are with publishing the revised curve(s). These data can be interpreted as evidence of summer temperature changes , on time scales up to multi-centennial , though millennial trends are not represented Cheers Keith At 13:14 10/07/2004, you wrote: Dear Keith, Coming back to our brief chat in Utrecht on the tree-ring data from northern Scandinavia, I would greatly appreciate if you could send me a plot showing the two series. Thanks in advance!
