    of temperature against the rotated PCs As noted elsewhere it is my view that this methodology will attenuate low frequency variance and artificially increase the calibration r2 with the information presented so far I think that simple averaging is more appropriate and any conclusions should be drawn from the information in their Figure 2 rather than the reconstruction The location of the 21 sites in St George and Luckman 2001 are from the same region as the sites in Luckman and Wilson 2005 which generated the reconstruction used in Osborn and Briffa 2006 and discussed previously at the blog here here here with a Rob Wilson criticism here and my reply here Its predecessor chronology from Luckman et al 1997 was widely used in TAR vintage reconstructions There are some differences between the St George Luckman reconstruction and the Luckman Wilson reconstruction which I ll re visit after this survey is finished Left Location map from St GEorge and Luckman 2001 right location map for Luckman and Wilson 2005 Reference St George R S and Luckman B H 2001 A proxy record of summer temperatures in the Central Canadian Rockies from Picea engelmannii treeline sites Canadian Journal of Forest Research 31 457 70 http www ltrr arizona edu sstgeorg PDFs CJFR2001 pdf Like this Like Loading Related This entry was written by Steve McIntyre posted on Apr 8 2007 at 1 53 PM filed under Noamer Treeline and tagged luckman treeline wilson Bookmark the permalink Follow any comments here with the RSS feed for this post Both comments and trackbacks are currently closed What is Consensus Science for Proxies Dulan Junipers and the Silk Road 5 Comments bender Posted Apr 8 2007 at 10 04 PM Permalink The St George Luckman url needs fixing http www ltrr arizona edu sstgeorg PDFs CJFR2001 pdf UC Posted Apr 9 2007 at 6 04 AM Permalink How can we verify that the low frequency secular and lower variability is preserved in the reconstructions Variance adjustment reduces low freq variability of the past sparser data If we had some kind of verification tool this would be detected right away In addition we have a divergence problem in 1980 present reconstructions Funny situation reconstructions are reliable given that there were no low frequency variations in the past temperatures In many threads Kalman smoothers etc have been suggested for reconstruction purpose But here s the big problem Kalman theory and Wiener and other related requires a dynamic model for the underlying stochastic process If we choose random walk we can directly prior to observations say that recent temperature rises are completely natural If we choose a white noise model we ll get opposite conclusion Then we can choose anything between those two models and get different conclusions This is a dead end we can t use reconstructions for system identification to choose the underlying stochastic model because reconstructions depend on that model Sorry again too much thinking aloud I guess jae Posted Apr 9 2007 at
