The locality can be characterized as overwet # with a cool summer and a long severe snowy winter. Annual precipitation can be in excess of 1000 mm. The duration of snow cover is # about 8-10 months. The vegetation season is from mid-June till the end of August; its mean duration is about 70-80 days (Kas'yanova, 2004). # The larch wood samples were taken nearby the upper timberline, where some trees grow side by side with tundra lichen. # # Olkhon Island (53 17'N, 107 38'E, 530 m.s.l.) is the largest island of Lake Baikal. The locality is dry with a medium warm summer # and a severe winter with little snow. The duration of snow cover is about 6-7 months. Vegetation season lasts from the third decade # of May till mid-September, its mean duration is about 138 days. (Kas'yanova, 2004). The larch wood samples were taken in the # northern part of the island, mostly occupied by larch taiga. # # The ecotope of trees near Irkutsk (52 14'N 104 11'E, 530 m.s.l., about 70 km WNW from the city of Irkutsk) is located in the southern taiga. # This site has optimal conditions of tree growth: a medium wet, warm summer, a medium severe winter with little snow. Snow covers the territory # for about 6-7 months. Vegetation starts at the end of the first decade of May and stops at the mid-September, about 148 days.

The problem of correlation between oxygen isotope chronologies from atmospheric precipitations fixed in ice cores and from cellulose molecules of tree rings. It is concluded that current ideas on these processes, in particular, the presented new results do not contradict the hypothesis on the presence of a natural mechanism of synchronization of isotope chronologies, which may be caused by the global character of the forcing action. Within this hypothesis, the use of the new "compression-extension" algorithm is justified and the possibility of correcting ice core chronologies using tree-ring isotope chronologies is shown. #------------------ # Publication # Authors: Valery A.

It has recently been proposed that the external forcing factor, as a characteristic of the total investigated territory, must cause a certain similarity of the essential properties of the simple processes induced by this forcing. The similarity is the main point of this investigation and is the basis for a constructive definition of the intersection of the sets of these induced processes as data sets. We specify the elements of the intersection of the sets as the "common signals" for each process (set). The common signals are computed by a new algorithm of "co-filtering", which is based on the trigonometric Fourier transform. We call the output of this algorithm the "co-filtered common signals" (CCS). We discovered that the CCS gave substantial contributions to the variances of the initial isotope series, which are more weakly correlated than their CCS. Next, we found that synchronous variations of the CCS of the temperature and precipitation for April-May and June-August induce synchronous variations in the CCS of the d18O-tree-ring series. Furthermore, the characteristics of such synchronism vary with time. We concluded that the CCS of the d18O-tree-ring series clearly express the external forcing factor even when there are significant differences in the vegetation conditions. #------------------ # Publication # Authors: Voronin, V.I., Schleser, G.H., and Helle, G. # Published_Date_or_Year: 2001-09-22 # Published_Title: Tree-Ring Stable Carbon Isotopes of Siberian Larch as Indicators of Changing Atmospheric CO2 and Humidity # Journal_Name: # Volume: # Edition: # Issue: # Pages: # Report_Number: # DOI: # Online_Resource: # Full_Citation: Voronin, V.I., Schleser, G.H., and Helle, G.
