   Rashit,
   Thank you for the data and pictures. They will help considerably.
   Keith is being criticised for how the trees used in the recent end of the Yamal chronology
   were selected from the larger quantities of trees available.
   For the two JAH tree used we have the rest of the chronology (25 cores in all).
   The 5 POR trees were selected from12 cores.
   For the 5 YAD trees used there would appear to be missing numbers. Do you have the other
   series which were left out?
   Attached are correlation reports for the JAH and POR sites. We need to be able to explain
   that the selection was based on a few trees from each site, tree were selected that clearly
   show the common high-frequency tree growth signal, and the longer series were selected to
   achieve a better overlap with the sub-fossil series and also to increase the preservation
   of low-frequency variance when using the corridor standardisation.
   We must show that the selection of trees was not made to support global warming. The YAD
   data shows an increase in tree growth and we need to show that all the trees from which we
   could have selected also show this increase.
   Thanks
   Tom

     Dear Tom,
     files with living trees data attached, that I use to update Yamal
     chronology
     (these data have been used among many others in Esper et al. 2009:
     [1]http://www3.interscience.wiley.com/journal/122374111/abstract?CRETRY=1&SRETRY=0).
     First letters in ID means river (valley):
     TNL - Tanlova-yakha;
     HDT, M, X - Khadyta-yakha;
     POR - Porza-yakha;
     all others - Yadayakhodyyakha
     (you can see the map of this area in Holocene, 2002, V. 12, N 6
     (ADVANCE-10k issue), fig 1, page 718).
     In Excel file - the same data but with age of rings (from
     central ring).
     As to photo - did you mean landscape photographs (old and recent)?
     Unfortunately no photos there are for Yamal.
     Stepan Shiyatov has published recently book with comparative photos
     in Polar Urals.
     Two examples from this book are attached.
     If you mean this kind of photographs I ask Stepan to find more
     impressive pictures.
     Best regards
